    _________________________
    (June 25, 2010)
    Before DUBINA, Chief Judge, EDMONDSON and HULL, Circuit Judges.
    HULL, Circuit Judge:
    Georgia death-row inmate Andrew Grant DeYoung (“DeYoung”) appeals
    the district court’s denial of his 
    28 U.S.C. § 2254
     petition for a writ of habeas
    corpus. After review and oral argument, we affirm.
    I. BACKGROUND
    A.     The Murders
    On June 14, 1993, DeYoung murdered his parents, Kathryn and Gary
    DeYoung, and his fourteen-year-old sister Sarah DeYoung.1 DeYoung planned the
    murders with David Hagerty. DeYoung v. State, 
    493 S.E.2d 157
    , 161 (Ga. 1997).
    DeYoung told Hagerty he wanted to kill his family to get money to start a business.
    DeYoung and Hagerty planned to kill DeYoung’s parents, his sister Sarah,
    and his sixteen-year-old brother Nathan by slashing their throats and then to set fire
    to the family’s home to cover up the evidence. 
    Id.
     On the night of the murders,
    DeYoung went upstairs, where his parents and sister were sleeping, and sent
    Hagerty to Nathan’s downstairs bedroom. 
    Id.
    DeYoung stabbed his mother repeatedly while she was sleeping in her
    bedroom upstairs; her screams awakened his father. As [DeYoung]
    struggled with his father, DeYoung’s sister Sarah came to the
    doorway of their parents’ bedroom. DeYoung slashed his father to
    death, and then stabbed and killed Sarah in the hallway. Hagerty heard
    a commotion upstairs, and changed his mind about killing Nathan.
    Nathan . . . heard stomping and banging noises coming from
    upstairs, and he heard his sister cry out and call his name. Upon
    finding that the phone was dead, Nathan escaped through his bedroom
    1
    When he committed the murders, DeYoung was nineteen years old, had finished high
    school and one year of college, and lived with his parents.

    window . . . .
    
    Id. at 161-62
    .
    Instead of setting the house on fire, DeYoung and Hagerty searched for
    Nathan. Meanwhile, Nathan fled to his neighbor Keith Harmon’s home. Nathan
    returned minutes later to the DeYoung house with Harmon, who brought a gun.
    Harmon saw DeYoung in the driveway and called out to him, but DeYoung fled.
    
    Id. at 162
    . Harmon had been the DeYoungs’ neighbor for about five years at the
    time of the murders. Harmon knew DeYoung and his siblings, and Nathan was a
    close friend of Harmon’s stepson.2
    Police arrived and found Gary, Kathryn, and Sarah DeYoung’s bodies.
    Sarah had scores of stab, cutting, and slash wounds on her neck, back, chest, arms,
    and hands. The wounds to the back of Sarah’s neck overlapped so much it was
    impossible to count them. There were at least seventeen wounds on Sarah’s back,
    several of which had prominent hilt marks. The blood spatter patterns indicated
    Sarah was on the ground while most injuries were inflicted.
    Kathryn DeYoung, like Sarah, had many stab wounds and cuts on her neck,
    back, and torso. Among them were a seven-inch-long cutting wound on her thigh
    and a five-inch-deep stab wound on her back that penetrated into her chest and
    2
    After the murders, Nathan lived with Harmon until he finished high school.
    3
    completely severed her aorta. One wound in her neck cut all the way through her
    trachea and also severed her left carotid artery and left external jugular vein.
    Kathryn had wounds going across her chest and wrapping around her right side,
    consistent with being attacked while lying down and rolling away from her
    attacker.
    Gary DeYoung suffered numerous wounds to his face and upper torso. He
    had a cut over his right eyebrow ridge, a deep stab wound in front of his right ear
    that fractured his jaw, stab wounds in his upper arm and neck, and numerous stab
    wounds to his chest. Gary also had two wounds on his right thigh, a six-inch-deep
    wound on his back, and a large chopping-type wound on his right biceps.
    B.    The Arrests
    Several hours after the murders, DeYoung returned home. Police noticed
    “scratches and abrasions present on his face, neck, hands and right arm.”
    DeYoung v. State, 
    493 S.E.2d at 162
    . At the police station, DeYoung gave a
    statement, later played at his trial, in which he told police he had spent the night at
    Hagerty’s house and denied involvement in the murders. 
    Id.
     DeYoung said he
    went for a two-hour walk in the middle of the night and got the injuries when he
    fell down.
    The police interviewed Hagerty, who admitted participating in the crimes.
    4
    Hagerty led police to evidence, including a footlocker and box he had helped
    DeYoung hide three days earlier, a knife consistent with the victims’ wounds, and
    a hand-drawn map showing the route to the DeYoungs’ home. 
    Id.
     The footlocker
    contained, among other things, personal notebooks written in DeYoung’s
    handwriting, articles or books with DeYoung’s name on them, and the hand-drawn
    map. The box contained materials for making pipe bombs.
    DeYoung and Hagerty were arrested and charged with the three murders.
    Hagerty pled guilty and received three concurrent life sentences. DeYoung pled
    not guilty.
    C.     Defense Counsel
    Attorneys Dennis O’Brien and Jimmy Berry were appointed to represent
    DeYoung. In April 1995, Jimmy Berry withdrew and the state trial court
    appointed Derek Jones as lead counsel, with O’Brien assisting. Both Jones and
    O’Brien were very experienced criminal defense attorneys.
    When Jones began representing DeYoung in April 1995, Jones had been an
    attorney for twenty years and had tried about ten capital cases. Jones obtained an
    acquittal in one, and most of the others “resulted in life sentences either at a plea,
    after extensive litigation, or at a jury verdict.”
    When O’Brien was appointed to represent DeYoung, O’Brien had tried 50 to
    5
    100 felony cases, including a number of murder cases, maybe one every couple of
    years, and he was involved in more murder cases that did not go to trial. O’Brien
    tried one death penalty case before DeYoung’s. During this case, O’Brien
    consulted with more experienced death penalty attorneys.
    D.    Pretrial Mental Health and Mitigation Investigation
    In their pretrial preparation, DeYoung’s counsel consulted (1) psychiatrist
    Dr. Alfred Messer, (2) neuropsychologist Dr. Robert Shaffer, (3) private
    investigator Joseph Stellmack, and (4) death penalty mitigation specialist Pamela
    Blume Leonard.
    Dr. Messer met with DeYoung at the jail twice. O’Brien sent Dr. Messer a
    number of documents, including the police report; police interviews with
    DeYoung, Hagerty, a former neighbor of the DeYoung family, a cellmate of
    DeYoung’s, and Nathan’s girlfriend; and transcripts from the probable cause
    hearing and Hagerty’s guilty plea. In his December 1994 report, Dr. Messer
    opined that the records and psychiatric evaluations were “sufficient to make a
    credible clinical judgment.”
    Dr. Messer’s report stated DeYoung was “alert, oriented, and cooperative,”
    and described no delusions or hallucinations. DeYoung had always been a loner,
    had little relationship with his siblings, and tended to avoid them. DeYoung’s
    6
    father gave him “very strict guidance,” but DeYoung received “very little physical
    discipline.” DeYoung tried to listen to his parents, who were the “most intellectual
    people [he] ever met,” and “always tried to make sure what [he] did would get [his]
    father’s o.k.” But DeYoung differed sharply with his parents on church
    attendance. His parents insisted the family attend church together, but DeYoung
    “became interested in occult matters and had books on Satanism.” DeYoung
    indicated his occult interest “was just curiosity” and “didn’t take me off course.”
    DeYoung wanted to develop a business career that would earn him enough
    money to become “independent of people.” He had an idea for an entertainment
    complex and tried to raise money for it, but “[b]y the time [he] could get something
    organized, somebody else stole the idea.” DeYoung was “very cynical about
    people, particularly authorities and police” and had “little trust that things will
    work out for him.”
    Dr. Messer diagnosed DeYoung with “[a]djustment [d]isorder with
    [w]ithdrawal,” but found “no evidence of psychosis, manic depressive illness or
    drug intoxication.” Dr. Messer also diagnosed DeYoung with “[b]orderline
    personality disorder . . . , severe, manifested by chronic feelings of emptiness,
    boredom, and failure.” Dr. Messer concluded that DeYoung suffered from
    “uncertainty and shifting ideals about long-term goals and career,” a “need to be in
    7
    control,” and “chronic irritability.” DeYoung demonstrated a “[p]ersistent pattern
    of unstable interpersonal relationships with overidealization or devaluation or
    cynical beliefs that people cannot be trusted, that they have stolen his ideas.”
    Dr. Messer found “[n]o significant physical problems,” but that DeYoung
    had psychosocial stressors “related to an adolescent consolidating his identity and
    the need to achieve according to standards set by highly demanding parents.” Dr.
    Messer’s 1994 report pointed out that DeYoung denied involvement in the murders
    and was completely able to help counsel at trial:
    Here is a man who steadfastly denies involvement in the murder of his
    parents and sister. There has always been a degree of power struggle
    with his parents about his ability to measure up to their standards.
    There is no long history of violence in this man. . . .
    The patient is completely able to cooperate with [counsel] in
    marshalling an appropriate defense at trial. I do not see psychiatric
    factors as part of his defense.
    Dr. Messer met with attorneys Berry and O’Brien, and they “discussed the
    need to present psychological evidence in mitigation, to try to explain the killings.”
    Dr. Messer and the attorneys “agreed it was important to tell the jury in the penalty
    phase about the crime of parricide generally, and the specific indications in Mr.
    DeYoung’s background and manner which fit the profile of a child who commits
    that crime.” Dr. Messer was “prepared to testify regarding parricide and [Dr.
    Messer’s] observations of [DeYoung] and his family in this regard.”
    8
    During this pretrial phase, Dr. Shaffer performed an 11-and-1/2 hour
    neuropsychological evaluation of DeYoung. Dr. Shaffer reviewed DeYoung’s
    high school and college records, plus a list of the items taken from DeYoung’s
    footlocker. Dr. Shaffer’s evaluation showed DeYoung had (1) an IQ of about 140,
    (2) an acute awareness of his intellectual abilities, and (3) no evidence of brain
    damage. DeYoung told Dr. Shaffer that his father “was of equally superior
    intellectual ability” and was one of the few people to whom DeYoung could relate,
    and that DeYoung and his father “competed intellectually.” DeYoung’s parents
    “were unquestioningly religious, and their unwavering acceptance of church
    dogma had caused [DeYoung] to seek out and explore as many different
    philosophies and religions as he could in a search for answers.”
    Dr. Shaffer found DeYoung had “a lack of empathy and emotional
    bluntness, as well as a very active fantasy life.” Dr. Shaffer diagnosed DeYoung
    with “Narcissistic Personality Disorder with symptoms of grandiosity.” Dr.
    Shaffer told DeYoung’s attorneys there “was evidence of some borderline
    psychotic symptoms, and possible schizoid tendencies,” but Dr. Shaffer “did not
    have enough information to make that diagnosis with a reasonable degree of
    professional certainty.”3
    3
    Dr. Shaffer asked to speak with Nathan DeYoung. A memo from Leonard, the
    mitigation specialist, states:
    9
    Investigator Stellmack spent about 260 hours working on the DeYoung
    guilt-phase and penalty-phase investigation. Stellmack compiled a list of potential
    mitigation witnesses, starting with those persons DeYoung suggested the attorneys
    contact, and added people or information to the list as he or the attorneys learned
    about them.4 Someone from the defense team tried to contact everyone on the list.
    The list described the attempts to contact the persons, plus a brief summary of the
    information the witnesses provided. For certain witnesses, Stellmack created more
    detailed interview notes.
    On April 3-11, 1995, investigator Stellmack interviewed DeYoung’s college
    teachers, assisted on an interview with Audrey Fridsma (the maternal
    grandmother), and conducted a telephone interview of Letha DeYoung (the
    [Dr. Shaffer] agrees that deeper digging is necessary and he’d like to meet with the
    brother, Nathan. However, Derek Jones tried to squelch that idea because it would
    alert the family that “we are trying to trash the parents” and he is holding on to the
    grandparents as mercy mitigation witnesses.
    Leonard’s memo went on to say that Dr. Shaffer “found no indications of any neurological
    problems” and “saw no indication of serious personality disorder or mental illness.”
    4
    The list of potential mitigation witnesses contained the following 45 names: DeYoung’s
    relatives Marvin and Letha DeYoung, William and Audrey Fridsma, Nathan DeYoung, Phillip
    and Brenda Veen, Susan Fridsma, John and Effie Vanderbilt, Karen Bielfuss, and Laura
    DeYoung; DeYoung’s fellow church members Rev. Chris Devos, Melissa Oezer, Clarence
    DeYoung, Cindy Verhage, Bert VanWyk, and Steve and Leslie Ruiter; DeYoung’s co-workers
    Kathy Albright, Beth Fisher, Judy Stevens, Barbara Grim, Jennifer Layton, Christin Edwards,
    and Sharon Koontz; DeYoung’s friends Kim Earlywine and Diane Butler; DeYoung’s neighbors
    Judy Polver Coffey, Cindy Etheridge, and Keith Harmon; DeYoung’s college professors Alan
    Lowther, Dr. Martha Myers, Martha Boyd, Dr. Charles Setzer, James Richardson, Dr. Philip
    Secrist, Brit Povlson, Steven Smalt, Merle King, Faye Jenson, and Dr. David Morgan; and
    DeYoung’s high school teachers Captain Csintyan, Velma Laughlin, and Bob Starrett.

    paternal grandmother). On April 14, 1995, Stellmack met with O’Brien, Jones,
    Leonard, and Dr. Shaffer to discuss mitigation issues.
    Stellmack also contacted DeYoung’s maternal and paternal grandparents
    about testifying in the penalty phase. Stellmack described them as “reluctant.”
    Stellmack stated that “[n]one of [the grandparents] were certain of attending the
    trial or testifying [as of April 1995], and I felt strongly that we needed to get them
    on board to the extent we could.”5
    Stellmack tried to ask Nathan DeYoung to testify in mitigation. Nathan was
    living with Harmon, who would not let Stellmack talk to Nathan. Later, Nathan
    left Harmon’s house and lived with his girlfriend; Stellmack tried again to contact
    Nathan. Stellmack got Nathan’s telephone number from his grandparents and tried
    to call Nathan “regularly,” “on an average three times a day.” Stellmack spoke to
    Nathan’s girlfriend several times and tried to explain to her “what the penalty
    phase was about and stressed to her that at some point in the future Nathan might
    want Andy to be alive.” Nathan’s girlfriend told Stellmack that Nathan “had no
    interest in testifying.” As of May 1995, Stellmack was only getting Nathan’s
    answering machine. Nathan never returned Stellmack’s calls.
    5
    In May 1995, Stellmack told O’Brien he should inform DeYoung that “no one is exactly
    jumping at the idea of testifying on his behalf.” Stellmack confirmed in his state habeas
    testimony that he had difficulty finding people to testify for DeYoung.
    11
    Investigator Stellmack tried to subpoena some of the Burger King co-
    workers DeYoung named as possible mitigation witnesses. When Stellmack went
    to Burger King to interview DeYoung’s co-workers, the manager asked him to
    leave. Burger King instructed its employees to notify its legal department if the
    employees were interviewed or subpoenaed. Stellmack spoke with DeYoung’s co-
    worker Kathy Albright at her home. The other employees Stellmack contacted told
    him they were not going to speak with him.
    In September 1995, Stellmack tried to locate Kim Earlywine and spoke to
    DeYoung family friend Diane Butler. Stellmack interviewed DeYoung’s minister6
    and the ROTC instructor at DeYoung’s high school and re-interviewed neighbor
    Judy Polver Coffey. Stellmack subpoenaed DeYoung’s school and work records.
    The defense attorneys considered calling Diane Butler to testify, but Jones
    decided not to use her as a witness. Jones had a “specific reason,” but Stellmack
    did not remember what it was. Jones and O’Brien also considered calling Leonard
    as a witness, but ultimately she was not called.
    In September 1995, Stellmack called the grandparents to firm up their travel
    arrangements. Stellmack and O’Brien met and spoke to DeYoung’s paternal
    6
    DeYoung’s minister, Chris Devos, was “hesitant to discuss a lot of details” and told
    Stellmack only “what you would expect from a pastor”: the DeYoungs “attended his church,
    they came to church on a regular basis, they seemed like a nice family.”
    12
    grandparents, Marvin and Letha DeYoung, before trial began.
    After Jones was appointed as lead counsel, Jones took “the main
    responsibility for [the] penalty phase,” and “insist[ed] on concentrating on the
    grandparents as mitigation witnesses.” Attorney Jones met with DeYoung about
    ten times before trial. Jones spoke with DeYoung’s grandparents, an uncle, some
    aunts, and other family members who lived across the United States and overseas.
    Jones’s strategy was to “rely on residual [doubt] . . . [and] the testimony of the
    family members in the sentencing.” Jones discussed this strategy with DeYoung,
    and DeYoung agreed with it. As to residual doubt, Jones tried to portray Hagerty,
    who was several years older than DeYoung, as the one “calling the shots.”
    Before Jones was appointed, DeYoung’s counsel considered having Dr.
    Messer testify in the penalty phase as to parricide and the DeYoung family’s
    internal dynamics. In an April 1995 colloquy with the state trial court, Berry
    explained the testimony the defense team was contemplating for Dr. Messer:
    Dr. Messer has done some extensive reading in [the parricide] area,
    and is knowledgeable about what happens sometimes in families, and
    especially after talking with Mr. DeYoung, and looking at the
    evidence in the case, with relationship to how this family unit worked,
    and what happened in this family unit, what transpired, and what the
    members of this family unit did as a family, and didn’t do as a family.
    All of these things he would be rendering an opinion about what . . .
    may have happened in this family. What may have triggered this kind
    of a scenario.
    ...
    13
    And what we would attempt to do would be to have Dr. Messer
    explain what other factors may have prompted [DeYoung’s] conduct,
    . . . as opposed to money. . . . It involves the dynamics of the family,
    the relationship with the father, these are the kinds of things that
    historically he has found in these kinds of cases, things like that.
    Counsel also considered retaining a parricide expert from California.
    In May 1995, after Berry withdrew and Jones was appointed, O’Brien and
    Jones explained to the state trial court that they had made a strategy decision not to
    use the California parricide expert. Jones stated that he and O’Brien were “still
    grappling” with the idea of presenting “some sort of psychological explanation,”
    but that “if all this psychological testing . . . comes to no fruition, then, you know,
    we’re obviously not going to put it up in any phase.” Counsel explained they
    would decide after discussing the matter with Dr. Messer and Dr. Shaffer:
    Mr. O’Brien:         What we think will probably happen . . . is to get
    Dr. [Shaffer] and his findings, conclusions with
    Dr. Messer. . . . [T]o sit down, let them compare
    notes, talk to us so that if there comes a point in
    time when and if the jury ever decides guilt, I
    would assume, and Derek the same, I assume, that
    the jury is going to want to know, how did this
    happen? And we were thinking that we would like
    to be able to explain it psychologically, at least
    give them that explanation. I mean, that’s what –
    Mr. Jones:           If there is one.
    Mr. O’Brien:         If there is one.
    Mr. Jones:           And, quite frankly, even if there is, you know,
    Dennis and I may look at it and say, well, you
    know, we might accept that but would a jury? And
    just jettison it.
    14
    Later, Jones and O’Brien met with Dr. Messer and Dr. Shaffer and decided
    not to present mental health evidence at the penalty phase because it was not
    helpful.7 Jones believed he and O’Brien researched the mental health area
    thoroughly. Jones stated, “[W]e consulted with experts, and experts did some
    evaluations, and it was not helpful.”
    The defense team collected information about parricide cases.8 But Jones, a
    very experienced criminal defense attorney, “didn’t put much stock in the
    psychiatric angle, and he pushed to rely on having family members plead for mercy
    in the penalty phase.” Moreover, the defense team’s jury consultant Maureen
    McGinley warned attorneys Jones and O’Brien that it would be a bad idea “to
    show disrespect for dead people in court” by presenting evidence tending to malign
    the victims, and that if there was sufficient evidence to allow the jury to infer
    something inappropriate occurred within the DeYoung family that prompted
    DeYoung to commit the murders, the attorneys should “leave it hanging and let the
    7
    A memorandum from this meeting contains the following notations:
    No delusional comp[ulsion] or irresistible impulse[.]
    No psychiatric defense!” . . .
    I am annihilated or I’ll annihilate them.
    Sh - People who perform parricide are not particularly violent - nor do they murder
    again.
    No remorse. No normal grief reaction.

    Leonard, the mitigation specialist, provided counsel with a list of documentary evidence
    to collect. Leonard suggested that parricide was a crime that “necessarily suggested an abuse
    situation.”
    15
    jury make [the inference] on their own.”
    As to non-mental health mitigation, Jones and O’Brien considered calling a
    number of witnesses that they ultimately did not call. Jones and O’Brien did not
    call them because counsel did not believe they would be helpful:
    [W]e thought that the family members would be the most effective.
    And there was other people – there was people who may have
    testified.   We had other people under subpoena, other people
    available, but we felt at the time that they would not be helpful.
    Some of the potential witnesses had information that would have been harmful.
    For example, DeYoung’s former girlfriend Daphne Collins said that DeYoung told
    her he hated his parents and wanted them dead. And DeYoung’s former best friend
    Cooper Etheridge said he was unsurprised that DeYoung killed his parents because
    DeYoung told Etheridge that he wanted to kill his parents and, in fact, had said “he
    wanted to kill everybody.”
    Jones thought the testimony of DeYoung’s family members, who were also
    related to the victims, was compelling. Jones did not know what else he could
    have presented that would have been as good as the family’s testimony:
    You know, when you have got the family of the victims, which I have
    never had one before where the family of the victims were also kin to
    the defendant, but when you have those people coming in and asking
    the jury to spare their grandson’s life, I don’t know how much more
    compelling mitigation evidence you can get.
    I mean, I thought their – I thought they had a lot to say to the
    jury, and I don’t know what else we could have presented, you know,
    16
    that would have been as good as that.
    I mean, there was nothing that I think that I could have
    presented that I didn’t that would have been helpful.
    I mean, I don’t really feel that I left, you know, a three hundred
    hitter, so to speak, sitting on the bench and didn’t call him to pinch-
    hit. I think we went with what we thought would work at the time.
    Although Jones was more involved in the mitigation phase than O’Brien
    was, O’Brien talked to many potential witnesses. O’Brien talked with a number of
    DeYoung’s teachers, including his college professors, but no one at the college
    said anything O’Brien or Jones thought would help. O’Brien also spoke to
    DeYoung’s high school teachers and fellow students.
    The defense team interviewed some of DeYoung’s Burger King co-workers.
    In particular, they investigated a co-worker named Jojo Moore, who other
    employees claimed dabbled in the occult. O’Brien and Jones “thought that perhaps
    maybe [Moore] had had some influence on [DeYoung], and we pursued that a little
    bit. That didn’t go anywhere.” O’Brien and Jones discovered that “there was
    some evidence . . . [that DeYoung] was selling pot out of the back of the Burger
    King.” The attorneys were hesitant to call co-workers who might know about that.
    Attorney O’Brien spoke with DeYoung more than twenty times before trial.
    O’Brien also spoke with Nathan DeYoung and his girlfriend.9 O’Brien spoke with
    9
    O’Brien told the state trial court at a May 1995 pretrial hearing:
    We’re trying to get [Nathan and his girlfriend Jennifer Dunlea] interested. But he
    will not cooperate at this point. We have asked him if he will come to my office, and
    17
    DeYoung’s grandparents and uncles and aunts. When DeYoung’s family members
    came to the DeYoung house to take care of matters involving Gary and Kathryn’s
    estate, O’Brien interviewed them, got their addresses, and stayed in touch.
    O’Brien and Jones realized that DeYoung’s grandparents “would be very
    significant in [the] case,” so O’Brien and Jones “started courting them right from
    the conceptual stages of the case.” Attorney O’Brien talked with the grandparents
    on the phone and went to see them in Iowa. At a December 1993 hearing, O’Brien
    told the state trial court he had traveled to Iowa, Ohio, and Michigan to meet with
    members of DeYoung’s extended family.
    E.     The Penalty Phase
    DeYoung’s trial started on September 25, 1995. DeYoung was convicted on
    all three counts of murder. The State then called penalty-phase witnesses to testify
    about burglaries at the DeYoungs’ church, at a DeYoung neighbor’s home, and at
    two Burger King restaurants where DeYoung worked. Items stolen were found in
    DeYoung’s room and in a storage bin DeYoung rented. The police found materials
    for designing and making pipe bombs in the DeYoungs’ garage, in DeYoung’s
    Jennifer. If they will let the doctor talk to them. Maybe. We’re not sure. We’re
    going to think about it, you know. I mean, we can’t force them to do it but we’re
    moving forward in any event.
    O’Brien told the state trial court that the defense team may not be able to get Nathan to testify,
    but “we have kind of laid it on the table to him, where we are. He knows what is going on.”
    O’Brien reiterated, “[W]e’re trying to get the brother involved in a positive way. We haven’t
    done it yet. We may never.”
    18
    room and van, and in the box that was hidden with the footlocker.
    The defense called five penalty-phase witnesses. Audrey Fridsma,
    DeYoung’s maternal grandmother, testified she was conflicted because three of her
    family members were killed by another family member. Fridsma testified, “Andy
    has to pay for what he did to our daughter and family, and so one side of me says,
    considering the terrible nature of this crime, that the death penalty would be [an]
    appropriate measure of justice.” But on the other side, Fridsma did not know how
    she could live with herself if she asked, “even in the name of justice, to put [her]
    grandson to death.” Fridsma told the jury she “would lean towards life in prison
    without parole,” because she “would like the opportunity to be able to forgive my
    grandson, even if I don’t feel like forgiving him right now.” A life sentence would
    give her that chance, but more importantly, would give DeYoung the opportunity
    to consider what he had done and ask for forgiveness from his family and from
    God.
    Robert Ohberg was DeYoung’s high school chemistry teacher. DeYoung
    was a good student who kept to himself and did not interact much with other
    students, though he got along with his lab partners well enough. DeYoung had no
    discipline problems, had a good sense of humor, and was “friendly enough if you
    initiated a conversation.” DeYoung never demonstrated any hostility, but was very
    19
    somber and serious, and he rarely smiled.
    DeYoung’s paternal grandmother Letha DeYoung testified that she and her
    husband visited DeYoung’s family about every two years, for three or four days at
    a time. DeYoung and his family got along fine, and DeYoung was respectful of
    his parents. Letha DeYoung corresponded regularly with DeYoung in jail and
    visited him twice. DeYoung wrote to his grandmother that he “was helping some
    inmates with GED tests, or with writing letters.” DeYoung wrote about his family,
    sent Letha DeYoung a poem about Gary DeYoung,10 and sent Nathan a birthday
    card and a graduation note.
    Letha DeYoung asked the jury for mercy for DeYoung, for “life not death.”
    Letha DeYoung said that “[o]ne of [her] reasons for asking [for a life sentence] is
    that God did not kill King David after David plotted the death of Uriah,” and she
    read that Bible passage to the jury. Letha DeYoung showed the jury childhood
    pictures of DeYoung. She testified about her memories of DeYoung and his
    10
    Letha DeYoung read DeYoung’s poem about his father:
    I had a father who talked with me, allowed me the right to disagree,
    to question and always answered me as well as he could and truthfully.
    He talked of adventures; horrors of war; of life, its meaning; what love was for;
    how each should always want to strive to improve the world to keep it alive.
    Stressed the duty we owe one another, to be aware each man is a brother.
    Words for laughter he also spoke a silly poem or a happy joke.
    Time goes on, some say I’m wise that I look at life with seeing eyes.
    My heart is open, my mind is free, I had a father who talked with me.
    20
    personal characteristics as he grew up:
    I have happy memories of Andy. He was always pleasant. He was
    cooperative. He was friendly. He was willing to talk. He is verbal.
    Most of those memories are, of course, from before the teens, or early
    teens.
    I don’t know what Andy was like in his home after he became
    involved in Satanism. Satanism does something to a person.
    One thing you have to break all ten commandments, and one of
    the commandments is honor your father and mother.
    I do not know what he was like, because the last time we visited
    in his home, he was 16.
    Did I notice anything unusual? I didn’t. If he was disrespectful
    it is nothing [that] is registering in my memory. I will remember
    something that stands out.
    I do remember, and kind of hate to say this, but I do remember
    one time when he was disrespectful. But it was – it was at a family
    reunion. He was 18. It was 1992. I hate to say this, but I just want
    you to know I don’t think Andy would have done – and it wasn’t that
    bad – been rude if he had not been under the influence of Satanism. I
    knew he was under its influence.
    Q.     Miss DeYoung.
    A.     I want to tell you about this incident.
    Q.     Is it a fair statement that you think that if Andy did this it was
    because of the powers of evil?
    A.     I think it is fair, yes. This is an incident I’m going to tell you
    about.
    Mr. Jones: Ma’am, I have no further questions.
    The Witness: Do you want me to talk, or do you want me to wait?
    Mr. Jones: No, ma’am.
    On cross-examination, the State asked Letha DeYoung to continue:
    I am just trying to be honest.
    As I told you, I have very happy memories of Andy except this
    one incident at 18, and he was under the influence of Satanism at the
    time.
    They were all ready to go. They were in our driveway.
    21
    We were going to say goodbye, and we were all standing
    around, his mom and his dad, and my husband and I, and I think an
    uncle and aunt, and I suppose cousins.
    Anyway, I don’t know. I guess his mother moved something.
    They were – she opened the back of the van, and she moved
    something that he had nicely put in place, and he was – he got irritable
    about it, and to be honest, I was embarrassed.
    Gary was embarrassed. His mom didn’t know what to say.
    But not one of us adults – I’m going to take the responsibility –
    not one of us adults corrected him.
    Now, it is possible that Gary corrected him as soon as they were
    out of sight of us, you understand.
    But that is the only time that I can remember Andy being rude
    ever.
    I told you my memories are happy of him, and that didn’t
    surprise me. I can tell you exactly what went through my mind at that
    time. It’s because he is under the influence of Satanism.
    It does you no good, ever. But that’s my only time.
    On redirect, Letha DeYoung said she loved DeYoung and would continue
    writing to him. She testified that, “[e]xcept for the grace of God, it could be any
    one of us” because “Satan doesn’t come to one and not to the other[,] [although]
    I’m not saying that he will come to everyone.” Letha DeYoung did not know
    when DeYoung got into Satanism, but she guessed it was when he was fourteen.
    Defense counsel said he had no more questions. Letha DeYoung asked to show
    the jury other pictures, because she “wanted [the jurors] to see the difference in
    Andy after he was into Satanism.” She showed the pictures, and then made a final
    plea for life instead of death:
    I would like to have life for Andy instead of death for the sake
    22
    of his brother.
    I don’t think Nathan, his brother, came this morning. His
    brother is very quiet. Just has difficulty being in front of people.
    It’s the only family member that Nathan has left. For that
    matter, if you take Andy’s life, it will be – Nathan will be the only
    family member we have left.
    I do want you to think carefully. I was hoping that the State
    would use Andy’s services.           I think you know he is gifted
    academically.     He would have to give his services without
    remuneration.
    But he is very good in computer programming. Also at one
    time he was good in the sciences, and I don’t know if he could be
    educated so he could take part in research, find a cure for cancer, any
    other disease. There are so many that have to be cured. I don’t know.
    But it is a reason that I would like to have Andy have life instead of
    death.
    Judith Coffey was a neighbor of the DeYoungs. Coffey’s daughter Amber
    was the same age as DeYoung, and the two were best friends from about age nine
    to thirteen or fourteen. Amber and DeYoung both loved animals, and they took
    care of animals together. They once found a baby squirrel that was hurt, and they
    tried to save it. Amber and DeYoung played at the creek: fishing, playing in the
    sand, catching salamanders and lizards and snakes. DeYoung treated the animals
    very well and “would never hurt anybody or anything. He was very, very
    compassionate.” Coffey never saw any cruelty in DeYoung, and one time when
    Nathan crushed a bug, DeYoung ran out and told him not to do that because
    “[t]hat’s Amber’s friend.” DeYoung and Amber got upset when Coffey’s son
    killed bees.
    23
    DeYoung got along fine with his family as far as Coffey knew. Coffey saw
    no arguments or fights, or “any discontent at all.” DeYoung was “always very
    respectful” of his parents, “always said, yes, sir [or] no, sir,” and “just seemed very
    polite, and very kind.” DeYoung was not aggressive with the other neighborhood
    children. Most of the time, “if there was going to be a confrontation, [DeYoung]
    and Amber would leave. . . . They didn’t seem to want to get into arguments, or
    fights, or anything. They seemed to shy away from them. I never saw any
    aggression at all.” Coffey “never saw . . . anything but congeniality.”
    On cross-examination, Coffey testified that DeYoung and Amber “drifted
    apart,” and DeYoung “got another crowd of kids to go around with,” including
    Cooper Etheridge and Wilbur Call. DeYoung, Etheridge, and Call went into
    Coffey’s house when Coffey’s garage was open and stole food from her
    refrigerator. After Coffey confronted the parents, Gary and Andrew DeYoung
    came to Coffey’s house and DeYoung apologized. Afterward, DeYoung returned
    on his own, apologized again, and said he should have stopped the others because
    what they had done was not right.
    DeYoung’s paternal grandfather, Dr. Marvin DeYoung, testified that, for a
    number of reasons, he was against giving DeYoung a death sentence:
    Now, when it comes to sentencing, I think there are some things
    I would like to say.
    24
    In the first place, I’m not in favor of the death sentence for
    Andy that’s for sure.
    Now, they are selfish reasons, of course. He is my grandson. I
    don’t want to see him put to death. But I think there are a lot of other
    reasons, too, why I say that.
    Andy is a different boy than the average – I use the term loosely
    – prisoner.
    Andy has a good mind. He has been raised in a Christian
    church. He has gone to Christian school, and he has been baptized.
    And baptism means that that’s God’s mark on him. And when God
    marks somebody that means something to God, and God doesn’t
    forget that.
    Dr. DeYoung testified that a life sentence would be better than death because
    DeYoung could “become a real useful servant of God”:
    [M]y plea for Andrew, for the jury, would be that if you give Andrew
    life in prison rather than death[,] I can see that he can become a real
    useful servant of God . . . .
    [The penal system] can be changed by somebody like Andrew,
    if he gives his life to Christ. He can become a real witness for the
    good news of salvation.
    Dr. DeYoung also testified that, although DeYoung had helped some people in the
    jail get their GEDs, he could do even better by bringing people to Christ. After
    presenting its witnesses, the defense put into evidence copies of DeYoung’s
    college and grade-school records, and payroll records showing DeYoung was
    employed from June 1, 1989 to June 24, 1993.
    The jury returned verdicts of death on all three counts. The jury found three
    statutory aggravating circumstances: (1) the murders occurred while DeYoung was
    25
    committing another capital felony; (2) the murders were committed for money or
    things of monetary value; and (3) the murders were outrageously or wantonly vile,
    horrible, or inhuman in that they involved depravity of mind and aggravated
    battery to the victims before their deaths. The state trial court imposed death
    sentences on all three counts.
    F.     Hearing on Motion for New Trial
    After trial, DeYoung received new counsel, Edwin Wilson, who had
    practiced law since 1977, had been a prosecutor, and had a general practice,
    including criminal defense.11 Wilson spent 77 hours reading the trial transcript and
    probably read it more than once. Wilson stated that “[t]he transcript looked pretty
    thorough to me.” He reviewed DeYoung’s trial counsel’s files, which were nearly
    12,000 pages.
    Wilson spoke with DeYoung and discerned potential issues from his
    transcript review. DeYoung was concerned counsel had not presented testimony
    from his co-workers. Wilson and DeYoung corresponded often, but DeYoung
    never mentioned any dysfunction within his family. Wilson spoke with attorneys
    Jones and O’Brien, the DeYoungs’ minister, and DeYoung’s grandmother. Wilson
    11
    Wilson represented DeYoung both in the motion for new trial proceedings before the
    state trial court and in his direct appeal. For brevity’s sake, we refer to Wilson simply as
    DeYoung’s appellate counsel.
    26
    was familiar with presenting ineffective assistance of counsel claims, and he
    intended to raise everything that appeared to be possible error, including any trial
    counsel performance issues.
    Through Wilson, DeYoung filed a motion for new trial alleging, inter alia,
    that his trial counsel were ineffective because they: (1) failed to develop and
    present psychological evidence in the penalty phase; and (2) failed to develop and
    present other available mitigation evidence in the penalty phase. The state trial
    court held an evidentiary hearing.
    Trial counsel Jones and O’Brien testified about their mitigation investigation
    and strategy, which is already outlined above. DeYoung gave Jones and O’Brien a
    list of at least twenty potential mitigation witnesses, including Kathy Albright, Kim
    Earlywine, and Judy Stevens, and DeYoung later submitted affidavits from
    Albright, Diane Butler, and Beth Fisher. Albright, a fellow manager at Burger
    King, stated that DeYoung “handled his authority well” at Burger King and had no
    problems relating to fellow employees or customers. DeYoung was quiet, did not
    have a lot of friends, and made no real attempt to associate with the other
    employees. DeYoung often “conveyed . . . his desire to go beyond Burger King to
    what he perceived as something better.” Overall, DeYoung “was a good kid who
    seemed to know what he wanted out of life . . . [and] had the intelligence to
    27
    achieve it.” DeYoung “appeared to have the potential to be a contributing and
    successful member of society.”
    Butler, who attended DeYoung’s church, stated that DeYoung “had a
    brilliant mind” but lacked “simple social skills” and had trouble relating to and
    interacting with others. Butler developed a friendship with DeYoung by visiting
    him in jail while he awaited trial.
    Fisher, another co-worker, stated that DeYoung handled his managerial
    position well, “got along well with the crew and customers,” and “never posed any
    problems.” DeYoung visited Fisher’s house on several occasions and played with
    Fisher’s children. Fisher trusted DeYoung and found him to be pleasant and “a
    good kid.” DeYoung often discussed plans to open his own Burger King or a teen
    club. DeYoung had intelligence and common sense and was “a high achiever with
    a lot of potential.”
    The state trial court denied DeYoung’s motion for new trial. As to
    DeYoung’s mitigation evidence claims, the state trial court found: (1) DeYoung
    was able to assist his attorneys in preparing for trial; (2) Dr. Messer did not see
    psychiatric factors as part of his defense; and (3) Dr. Shaffer’s extensive testing
    and Dr. Messer’s consultations produced no “useable psychological evidence for
    the defense.” The court found that the affidavits of Albright, Butler, and Fisher
    28
    indicated their testimony would have been similar to that already presented by
    counsel in the penalty phase and would not have changed the outcome:
    A review of the affidavits of Diane Butler, Kathy Albright, and Beth
    Fisher, submitted to supplement the record, indicates their relationship
    as church members and/or as fellow workers of DeYoung and their
    observations of him as intelligent, a good worker, and pleasant to be
    around, and of his hopes to improve his position in life. Similar
    testimony was presented at trial through a former teacher, a former
    neighbor, and three of DeYoung’s grandparents. In view of the strong
    evidence connecting DeYoung to the murders of his parents and his
    sister, it is unlikely this cumulative evidence, if presented, would have
    changed the outcome of the trial.
    G.    Direct Appeal
    DeYoung, through counsel Wilson, appealed, claiming he had ineffective
    trial counsel for failure to call Butler, Albright, and Fisher as witnesses in the
    penalty phase. The Georgia Supreme Court affirmed. DeYoung v. State, 
    493 S.E.2d 157
     (Ga. 1997). On direct appeal Wilson did not include a claim of
    ineffective trial counsel for failure to investigate and introduce pyschological or
    any other mental health evidence.
    The Georgia Supreme Court found no error in the state trial court’s
    conclusion that DeYoung did not show ineffective counsel at the penalty phase
    from not calling Butler, Albright, and Fisher:
    [T]rial counsel extensively investigated DeYoung’s background,
    interviewing his teachers, other students at his school, co-workers,
    friends and family members. DeYoung was examined by both a
    29
    psychologist and a psychiatrist and the defense presented mitigation
    testimony from a former teacher, a former neighbor, and appellant’s
    grandparents. Counsel elected not to offer Butler, Albright, and Fisher
    as mitigation witnesses since their testimony would have been
    cumulative.
    Decisions regarding which witnesses to present are matters of
    trial strategy. When founded on legitimate evidentiary concerns, such
    decisions do not constitute ineffective assistance of counsel. The
    affidavits submitted at the motion for new trial reveal that Albright
    and Fisher were appellant’s co-workers at Burger King. The trial court
    noted in its order denying the motion for new trial that the affidavits
    of these witnesses demonstrated that DeYoung was “intelligent, a
    good worker, and pleasant to be around, and [had] hopes to improve
    his position in life,” and their testimony would have been similar to
    that presented by the witnesses who did testify.
    We conclude that none of the enumerated actions or omissions
    by counsel constitute ineffective assistance of counsel.

    H.     State Habeas Proceedings
    DeYoung through new counsel petitioned for a writ of habeas corpus in state
    court.12 He claimed, inter alia, that Wilson was ineffective for not raising and
    proving more claims in his motion for new trial and direct appeal, especially the
    claim that his trial counsel were ineffective in their investigation and presentation
    12
    During the state and federal habeas proceedings, DeYoung was represented by his
    present counsel. In the context of DeYoung’s state habeas proceedings, we refer to the state
    trial-level court as the “state habeas court.” The judge who presided over DeYoung’s state
    habeas proceedings was not the same judge who presided over DeYoung’s trial.
    30
    of mitigation evidence. The state habeas court held an evidentiary hearing.
    DeYoung introduced documentary evidence and more than 90 affidavits as
    evidence of what appellate counsel Wilson and trial counsel Jones and O’Brien
    could have developed as mitigation evidence.13 We summarize the pertinent
    evidence.
    1.      DeYoung’s New Mental Health Evidence
    DeYoung’s new mental health evidence mainly focused on showing that,
    with more evidence, his diagnosis was “schizotypal” personality disorder and
    dysthymia rather than his pretrial experts’ diagnoses of narcissistic personality
    disorder and borderline personality disorder. Dr. Faye Sultan, a psychologist,
    interviewed DeYoung in prison and reviewed trial excerpts and 62 affidavits about
    DeYoung and his family. Dr. Sultan diagnosed DeYoung with (1) dysthymic
    disorder, indicating he “experience[d] chronically depressed mood,” loss of interest
    in life, decreased capacity to experience pleasure, social withdrawal, and feelings
    of inadequacy, irritability, and excessive anger; and (2) schizotypal personality
    disorder, indicating he suffered “a pervasive pattern of social and interpersonal
    13
    Wilson, as DeYoung’s attorney, did not raise ineffectiveness claims regarding mental
    health evidence on direct appeal or regarding other mitigation evidence (apart from the Butler,
    Albright, and Fisher claim) either in the motion for new trial or on direct appeal. Therefore,
    DeYoung had to raise those claims through the lens of Wilson’s alleged ineffectiveness for
    failing to raise them either in the motion for new trial or on direct appeal.
    31
    deficits marked by acute discomfort with and reduced capacity for close
    relationships, cognitive and perceptual distortions, and eccentricities of
    behavior.”14 Dr. Sultan opined that these disorders (1) “severely compromised Mr.
    DeYoung’s capacity to think clearly and to handle normal life stressors, to regulate
    his behavior, and to meet the requirements of daily living”; and (2) “rendered him
    extraordinarily vulnerable in interactions with individuals who were authoritarian,
    exploitative and manipulative in their manner of relating,” such as David Hagerty.
    DeYoung’s state habeas counsel provided Dr. Messer and Dr. Shaffer with
    more records and information about DeYoung and his family. With this new
    information, both Dr. Messer and Dr. Shaffer concluded that “schizotypal
    personality [disorder] is the more appropriate diagnosis” for DeYoung. Dr. Messer
    opined that a diagnosis of dysthymia (a mood disorder) and schizotypal personality
    disorder “is entirely consistent with what I observed in Mr. DeYoung in 1994 and
    chronicled in my psychiatric report to [trial counsel] Mr. O’Brien.” However,
    “[n]either diagnosis suggests . . . psychosis.” Dr. Shaffer also testified that his
    “initial diagnosis of Narcissistic Personality Disorder was made based on
    Andrew’s suspiciousness, social withdrawal and alienation, and apparent
    grandiosity.” Dr. Shaffer added that, “[i]nterpreting these features now in light of .
    14
    No one, however, diagnosed DeYoung as having schizophrenia (a psychosis) or any
    other psychosis.
    32
    . . Andrew’s history and familial background, I find that Schizotypal Personality
    Disorder is an appropriate diagnosis.”
    Dr. David Lisak, a clinical psychologist, never saw DeYoung but opined by
    affidavit that “there was substantial information available between 1993 and 1995
    that incest might have occurred in the DeYoung family, and that Andrew DeYoung
    himself may have been victimized.”15 However, Dr. Lisak cited no evidence from
    DeYoung, his only surviving sibling Nathan, or anyone else stating that sexual
    abuse actually occurred to DeYoung or his siblings.
    2.      Nathan DeYoung’s Affidavit
    In an affidavit, Nathan DeYoung stated he was not asked to testify in the
    penalty phase. Nathan said that giving penalty-phase testimony “would have been
    extremely difficult for me to do,” but “if I had been asked to do it, I would have
    said that I preferred the option of life without parole.” Nathan never mentioned
    15
    The information Dr. Lisak relied on for this “might have” happened opinion was: (1)
    parricide is a rare crime, and often the child-murderer was the victim of intra-family abuse; (2)
    DeYoung’s parents and sister were stabbed two to three dozen times each, demonstrating
    “extreme rage or hatred”; (3) DeYoung had “withdrawn behavior”; (4) Marvin DeYoung (the
    grandfather) sexually abused two grandchildren and “made a sexual overture” toward his
    daughter; (5) acquaintances of DeYoung’s family noted Gary and Sarah DeYoung were “always
    holding hands” and “always together,” and Sarah “drape[d] herself all over her father until she
    seemed much too old to do so”; (6) DeYoung once told an acquaintance “that he wished
    someone would take him away from his family because ‘his dad did stuff to them that he didn’t
    like’”; and (7) witnesses reported “numerous oddities of the DeYoung family,” including a
    cluttered home, an “extremely socially dysfunctional” manner, and “no physical affection or
    emotional closeness” other than between Gary and Sarah.
    33
    any possible abuse within the DeYoung family. Nathan did not dispute
    investigator Stellmack’s testimony that Stellmack spoke with Nathan’s girlfriend
    and repeatedly left messages for Nathan and that Nathan did not return his calls.
    3.     The State’s Mental Health Expert, Dr. Thomas Sachy
    The State presented evidence that DeYoung did not have either dysthymia or
    schizotypal personality disorder. For example, after reviewing the same affidavits
    and records about DeYoung and his family, forensic neuropsychiatrist Dr. Thomas
    Sachy conducted a three-hour, in-person neuropsychiatric evaluation of DeYoung
    in April 2001. Dr. Sachy found “no gross evidence of cognitive dysfunction
    consistent with a Schizophreniform disorder.” Dr. Sachy saw no psychotic
    symptoms and found that DeYoung’s “thought processes were linear and goal
    directed throughout the interview.” DeYoung displayed no evidence of “odd or
    magical thinking, unusual perceptions, suspiciousness or inappropriate
    affect/behavior.” DeYoung’s reported leisure activities in prison demonstrated a
    “level of social interaction uncharacteristic of Schizotypal [Personality Disorder].”
    Importantly, DeYoung also denied any symptoms of depression and demonstrated
    no evidence of clinically significant depression. DeYoung said he missed his
    parents.16
    16
    DeYoung said his father “whupped him once or twice for some minor infraction, but
    . . . didn’t say that he was ever physically abused by his father.”
    34
    Dr. Sachy also stressed that DeYoung “did demonstrate signs of malingering
    behavior which only casts doubt upon the previous findings of Dr. Sultan.”17 Dr.
    Sachy concluded DeYoung was “in constant control of his behavior,” as evidenced
    by his “meticulous planning” of the murders. DeYoung had “no documented
    history of . . . a psychiatric diagnosis” before the murders. Dr. Sachy expressly
    opined that DeYoung did not have either dysthymia or schizotypal personality
    disorder.18
    I.     State Habeas Court Order
    The state habeas court denied DeYoung’s habeas petition. The state habeas
    court (1) summarily denied all claims that already had been decided on direct
    17
    Dr. Sachy also disagreed with Dr. Sultan’s conclusion that DeYoung was
    “extraordinarily vulnerable in interactions with individuals who were authoritarian, exploitative
    and manipulative.” Dr. Sachy found no evidence of this in the record and, indeed found contrary
    evidence in DeYoung’s correspondence with his attorneys, in which he requested documents or
    directed the attorneys to take certain actions or make certain investigations; in DeYoung’s
    imperviousness to manipulation by police officers; and in DeYoung’s leadership role in his
    burglaries with Hagerty and Marlow. Far from being vulnerable to authoritarian and
    manipulative people, DeYoung himself “is likely the manipulator.”
    18
    Dr. Sachy cited “the extensive evidence of Mr. DeYoung’s clear thinking, socially
    appropriate behavior and successful functioning on a daily basis.” Dr. Sachy noted that
    DeYoung was able to perform the responsibilities of a manager at Burger King, to “co-exist with
    his family without documented behavior disturbances or acts of violence,” to compose lengthy
    treatises documenting records of past criminal activities and plans for future ones, to commit a
    number of burglaries without detection, to excel at school and in the ROTC program. Moreover,
    with respect to the murders themselves, DeYoung was able to: (1) “‘cleanse’ his room of
    incriminating materials prior to the murder[s] and hide them in a remote location”; (2) “murder
    three family members sequentially, without decompensating psychologically”; and (3) “return to
    his home after the murders and calmly and consistently tell the police that he had nothing to do
    with the deaths of his family.”
    35
    appeal, noting it had no authority to revisit those issues, (2) determined that
    DeYoung’s new ineffective assistance claims were procedurally defaulted because
    they could have been raised by new appellate counsel Wilson in the motion for
    new trial and on direct appeal, and (3) found that, in any event, DeYoung had not
    shown deficient performance by either trial or appellate counsel or any prejudice.19
    DeYoung argued that his trial and appellate counsel’s failure to preserve
    certain issues for habeas review constituted ineffective assistance of counsel so as
    to satisfy the cause prong of the cause and prejudice test for excusing procedural
    default. The state habeas court found that, even assuming that were true,
    “DeYoung has not shown that the identified instances of alleged ineffective
    assistance of counsel were of sufficient importance that they prejudiced his defense
    with regard to the verdict of guilty and sentence of death such that the otherwise
    valid procedural bar should be excused.” The state habeas court concluded that all
    19
    The state habeas court said:
    This court has carefully reviewed the trial record, the evidence adduced at the
    evidentiary hearing, the arguments of counsel, and the law applicable to DeYoung’s
    claims. This court concludes that, even if this claim was not procedurally defaulted,
    which this court has ruled, trial counsel and appellate counsel performed both
    reasonably and effectively in their representation of DeYoung. DeYoung has failed
    to establish that the performance of trial counsel or appellate counsel fell below an
    objective standard of reasonableness or that DeYoung suffered actual prejudice as
    a result of any unreasonable performance by trial counsel or appellate counsel.
    DeYoung’s claim of ineffective assistance of trial counsel and appellate counsel
    must fail both as a separate claim of relief and as cause to excuse the procedural
    default of issues raised for the first time in this habeas corpus proceeding.
    36
    DeYoung’s ineffective trial counsel claims not raised in DeYoung’s motion for
    new trial and on direct appeal were procedurally defaulted, and that DeYoung
    showed “[n]o cause or prejudice . . . to excuse this procedural default.”
    Alternatively, the state habeas court denied each ineffective assistance claim
    on the merits, as outlined below. The court rejected DeYoung’s claim that Jones
    and O’Brien failed to conduct an adequate pretrial investigation into the State’s
    case and potential defenses. The state habeas court found that: (1) Jones and
    O’Brien’s strategy for the penalty phase was to rely on residual doubt and the
    testimony of DeYoung’s family members; (2) for residual doubt, counsel tried to
    paint Hagerty as being in control on the night of the murders, and to suggest other
    persons may have been involved; (3) counsel considered presenting mental health
    evidence, but after consulting with Dr. Messer and Dr. Shaffer, counsel decided
    mental health evidence would not be helpful; (4) counsel considered presenting
    mitigation witnesses who were not members of DeYoung’s family, but concluded
    for strategic purposes “that the family members would be the most effective
    witnesses in mitigation and that the other people available as witnesses would not
    be helpful, especially since some of the other potential witnesses could testify . . .
    to matters that would do harm to [DeYoung’s] case.”
    The state habeas court concluded that the performance of DeYoung’s trial
    37
    counsel was not ineffective, stating that “[t]he mere fact that other witnesses might
    have been available or that other testimony might have been elicited from those
    who testified is not a sufficient ground to prove ineffectiveness of counsel.” The
    state habeas court noted that the issue of which witnesses to call, if any, “is the
    epitome of a strategic decision,” one that courts will seldom second-guess.
    The state habeas court also rejected DeYoung’s claim that Jones and
    O’Brien were ineffective for not presenting expert testimony on parricide. The
    state habeas court found trial counsel explored the possibility of presenting
    parricide testimony, and information on parricide was contained in trial counsel’s
    files, but counsel told the state trial court that “they made a strategy decision not to
    pursue parricide as a theory in mitigation.” The state habeas court also noted that
    the jury consultant hired by DeYoung’s counsel warned them it would be
    inappropriate to put forth evidence tending to malign the victims.
    Based on the record, the state habeas court found that “trial counsel were
    fully aware of the concept of parricide but made a strategy decision to pursue a
    case of [residual] doubt and pleas for mercy from [DeYoung’s] family members.”
    Moreover, the state habeas court determined that this strategic choice “was
    reasonable in light of the fact that no one, including Petitioner himself, gave any
    indication that any family dysfunction existed.” The strategy was also reasonable
    38
    “in light of the fact that one of trial counsel’s own experts suggested that they not
    malign the names of the victims, which would be required when presenting a
    theory of parricide to the jury.”
    Because counsel made a reasonable strategic decision to forgo the use of
    parricide testimony, counsel’s performance was not deficient. In any event,
    DeYoung could not show prejudice as to this claim.
    Similarly, the state habeas court denied DeYoung’s claim that his trial
    counsel were ineffective for not presenting evidence of sexual abuse. DeYoung
    could not satisfy the performance prong because he failed to show he actually
    suffered any sexual abuse:
    Petitioner’s only alleged “evidence” of [sexual] abuse was the fact
    that Petitioner’s father and sister had a close relationship; that
    Petitioner’s family played a game that involved sitting on each others’
    laps; . . . and that Petitioner once told someone that his father did
    “stuff” to him and his siblings that he did not like. Clearly, none of
    this “evidence” suggests, much less establishes, that Petitioner was
    sexually abused by his father.
    []        Finally, Petitioner himself has never testified that he was
    sexually abused by his father when he was growing up. Clearly, the
    best and most reliable evidence of any abuse would come from
    Petitioner himself. However, Petitioner has failed to so attest to any
    alleged abuse and no other evidence establishes any such abuse.
    The state habeas court also found that DeYoung failed to establish the prejudice
    prong of this ineffective counsel sex-abuse claim.
    The state habeas court also rejected DeYoung’s claim that Jones and
    39
    O’Brien failed to adequately investigate or present mental health testimony. The
    state habeas court found that DeYoung was evaluated before trial by Dr. Messer
    and Dr. Shaffer and DeYoung did not “report any significant dysfunction in his
    home, any unusual problems with his parents, ideas of reference, depression, or
    any other significant traits of schizotypal personality disorder or dysthymia.”
    Although trial counsel considered calling Dr. Messer in the penalty phase, Dr.
    Messer and Dr. Shaffer told counsel that DeYoung had “no real psychiatric
    defense”:
    Although trial counsel considered, at one point, utilizing Dr. Messer
    during the penalty phase of trial, during a meeting with Petitioner’s
    counsel, Dr. Messer, and Dr. Shaffer prior to trial, the doctors
    informed counsel that, despite their diagnosis of personality disorders,
    Petitioner had no real psychiatric defense. The doctors further
    reported that the best they could attest to was that Petitioner did not
    show any remorse, or have a normal grief reaction, but rather had the
    attitude of “I am annihilated or I’ll annihilate them.”
    The state habeas court determined that an ineffective assistance claim “must
    be evaluated based upon information known to counsel at the time.” And
    DeYoung himself did not personally exhibit behavior or symptoms of schizotypal
    personality disorder or dysthymia to Dr. Messer or Dr. Shaffer, who both
    interviewed him. The state trial court found that, at the time of trial, there was no
    cause for Jones and O’Brien to believe that further investigation of mental health
    evidence was needed:
    40
    Clearly, at the time of trial, Petitioner did not reveal any behavior or
    indications that he might suffer from traits of schizotypal personality
    disorder or dysthymia to Dr. Messer or Shaffer. Additionally, as
    noted above, the myriad of family and friends contacted by the
    defense team did not give counsel any reason to believe that Drs.
    Messer or Shaffer needed any additional information or background
    about Petitioner’s childhood; rather, the family and friends reported
    that Petitioner belonged to a quiet, religious, middle-class family who
    did not share much of their lives with outsiders. Thus, there were no
    indications to trial counsel nor to Drs. Messer or Shaffer that a further
    investigation into Petitioner’s background was warranted, or that
    Petitioner might suffer from a mental ailment more useful to a defense
    or mitigation phase of a death penalty case than those diagnosed by
    the doctors.
    DeYoung had “a responsibility to assist in his defense and provide honest and
    accurate information to his counsel and defense team.” Because DeYoung did not
    indicate any traits of schizotypal personality disorder or dysthymia to Dr. Messer
    or Dr. Shaffer, Jones and O’Brien “were not unreasonable to rely upon their
    experts’ opinions that [DeYoung] was not laboring under a psychological disorder
    or disease that should be presented to the jury in mitigation.”20
    The state habeas court “place[d] no weight” on Dr. Sultan’s testimony in her
    affidavits. The state trial court concluded that Jones and O’Brien, “[w]hen making
    20
    The state habeas court also stated that (1) DeYoung had no previous history of mental
    illness or mental health treatment, (2) no potential witness interviewed by the defense team
    indicated DeYoung might have a mental illness, and (3) the evaluations conducted by Dr. Messer
    and Dr. Shaffer failed to reveal any mental infirmities they thought would be useful to present.
    The state habeas court determined that the affidavits of Dr. Messer and Dr. Shaffer, reflecting
    different opinions based on information not available to them before trial, were based on
    hindsight and had no probative value.
    41
    their decision not to present mental health evidence to the jury, . . . made an
    appropriate and reasonable decision based upon information available to them at
    the time.”
    The state habeas court also denied DeYoung’s claim that Jones and O’Brien
    failed to reasonably investigate and present other mitigation evidence. The state
    habeas court noted at the outset that this claim “relies exclusively upon affidavits
    secured by Petitioner’s current counsel that tell tales of Petitioner’s parents’ and
    grandparents’ lives and neighbors’, friends’ and acquaintances’ impressions of
    Petitioner’s life and the lives of Petitioner’s siblings.” The state habeas court
    found “that an overwhelming amount of the testimony contained within these
    affidavits is inadmissible,” and the court “disregard[ed] those portions of the
    affidavits that contain inadmissible evidence.” The state habeas court noted that
    the mere fact that other testimony or witnesses might have been available does not
    establish ineffective assistance of counsel.
    DeYoung himself presented counsel and Stellmack with names of potential
    mitigation witnesses, all of whom Stellmack contacted, or tried to contact. The
    state habeas court found that “trial counsel contacted or attempted to contact a
    tremendous number of potential witnesses for use during the penalty phase of
    trial.” The state habeas court determined that the “overwhelming majority of the
    42
    witnesses now presented by Petitioner via affidavit were not known by trial
    counsel prior to trial.”
    The state habeas court found that Jones and O’Brien “conducted a full and
    reasonable investigation into potential mitigation witnesses,” and they “were not
    unreasonable for failing to uncover the names of additional possible witnesses that
    were unknown to them at the time of trial.” Moreover, “it was reasonable for trial
    counsel to believe that Petitioner had given them all of the names of possible
    witnesses that might have the ability to assist during the mitigation phase of trial.”
    The state habeas court determined that:
    It would be patently unreasonable to expect counsel to go on a wild
    goose chase for names of individuals tangential to Petitioner’s life
    from whom a slim possibility of useful and mitigating information
    might arise. Rather, it was much more reasonable to rely upon
    Petitioner to supply defense counsel with the names of those people
    most likely to have information about Petitioner’s own life and
    character. Therefore, trial counsel was not ineffective for failing to
    discover alleged potential mitigation witnesses of whom they were not
    aware prior to trial, and counsel’s performance in discovering
    potential mitigation witnesses was not deficient.
    Additionally, the state habeas court found that those potential witnesses
    contacted by DeYoung’s trial counsel who later submitted affidavits in the habeas
    proceedings “were not as forthcoming with their information and knowledge prior
    to trial as they seem to have been for Petitioner’s habeas corpus counsel.”
    Accordingly, DeYoung did not show that the evidence submitted in the affidavits
    43
    was available at the time of trial, and Jones and O’Brien’s performance was not
    deficient for not eliciting this new evidence.
    Importantly too, the state habeas court found that many of the witnesses
    whom DeYoung’s trial counsel interviewed and later submitted affidavits would
    have revealed information harmful to DeYoung’s case. The state habeas court
    cited witnesses Cooper Etheridge and Daphne Collins, who “would have testified
    that [DeYoung] talked about hating his parents and family and wanting to kill
    them.” The state habeas court found that “while these witnesses may now have
    information that could have been beneficial to Petitioner’s case, the damage that
    would have been done by this other information far outweighs the benefits to the
    point that no reasonable attorney would have risked presenting such individuals as
    witnesses on Petitioner’s behalf.” Thus, the state habeas court concluded “it was
    entirely reasonable for counsel to not present witnesses such as Mr. Etheridge and
    Ms. Collins as witnesses on petitioner’s behalf.”
    As to DeYoung’s claim that his trial counsel failed to call Nathan in the
    penalty phase, the state habeas court noted that: (1) trial counsel testified during
    pretrial proceedings that “extensive efforts were made to contact Nathan, to no
    avail,” and that Stellmack called “regularly,” about three times per day, but reached
    an answering machine; (2) at the habeas hearing, Stellmack testified he tried more
    44
    than once to contact Nathan; (3) after Nathan moved out of Harmon’s house,
    Stellmack tried to speak with Nathan several times, but was forced to leave
    messages; and (4) Nathan never returned Stellmack’s phone calls. The state habeas
    court found that “although trial counsel made reasonable attempts to contact
    Nathan and to speak with him in an effort to possibly secure his testimony, Nathan
    clearly had no intention of assisting the defense in Petitioner’s case.” Because
    Jones and O’Brien could not force Nathan to speak with them, their performance
    was not deficient.
    Alternatively, the state habeas court concluded DeYoung could not show
    prejudice from any failure to call Nathan because DeYoung “failed to establish
    what types of information trial counsel could have learned from Nathan DeYoung
    if he had spoken with counsel prior to trial that would have affected the outcome of
    the trial.”
    As to potential issues not raised in the motion for new trial or on direct
    appeal, the state habeas court found that appellate counsel Wilson was in contact
    with DeYoung throughout the representation, including through written
    correspondence, and none of DeYoung’s correspondence with Wilson mentioned
    any dysfunction within DeYoung’s family.
    The state habeas court determined DeYoung did not show that Wilson failed
    45
    to present any “significant and obvious issues on appeal.” The state habeas court
    found that Wilson’s “investigation into and preparation for [DeYoung’s] appeal,
    and [Wilson’s] winnowing down of appealable issues to the 18 ‘significant and
    obvious’ issues that he raised at the motion for new trial and on appeal, constitute
    effective performance.” DeYoung did not show he was prejudiced by Wilson’s
    conduct because “raising any additional instances of ineffective assistance of trial
    counsel would not have been successful on appeal.” As a result, the state court
    concluded, “DeYoung’s claim of ineffective assistance of appellate counsel must
    fail both as a separate claim of relief and as cause to excuse the procedural default
    of issues raised for the first time in this habeas corpus proceeding.”
    J.    State Habeas Appeal
    On January 20, 2004, the Georgia Supreme Court denied DeYoung’s
    application for a certificate of probable cause to appeal. The United States Supreme
    Court denied DeYoung’s petition for certiorari. DeYoung v. Schofield, 
    543 U.S. 892
    , 
    125 S. Ct. 168
     (2004).
    K.    Federal Habeas Proceedings
    In May 2004, DeYoung filed his § 2254 petition, which alleged, inter alia,
    claims of ineffective trial and appellate counsel. In June 2007, the district court
    denied as procedurally barred all the claims DeYoung did not raise in his motion
    46
    for new trial or on direct appeal.
    In August 2007, the district court issued a final order finding DeYoung was
    not entitled to federal habeas relief or an evidentiary hearing. The district court
    found trial counsel were not ineffective in investigating and presenting mitigation
    evidence and, thus, appellate counsel was not ineffective in failing to raise this
    issue in the new trial motion or on direct appeal. The district court granted a
    certificate of appealability (“COA”) on DeYoung’s ineffective trial and appellate
    counsel claims.21
    II. STANDARD OF REVIEW
    We review the district court’s denial of DeYoung’s § 2254 federal habeas
    petition de novo. Cummings v. Sec’y for the Dep’t of Corr., 
    588 F.3d 1331
    , 1355
    (11th Cir. 2009), petition for cert. filed (U.S. Jun. 7, 2010) (No. 09-11289).
    However, we, like the district court, “owe deference to the final state habeas
    judgment.” Reed v. Sec’y, Fla. Dep’t of Corr., 
    593 F.3d 1217
    , 1239 (11th Cir.
    2010), petition for cert. filed (U.S. Jun. 7, 2010) (No. 09-11314). This Court’s
    review is governed by the Antiterrorism and Effective Death Penalty Act of 1996
    21
    The district court also granted a COA as to ten other issues, including the district
    court’s denial of DeYoung’s motion for an evidentiary hearing. We find no error in the denial of
    an evidentiary hearing and affirm on that issue. DeYoung makes no arguments as to the other
    issues for which he was granted a COA. DeYoung therefore waives those issues. See Herring v.
    Sec’y, Dep’t of Corr., 
    397 F.3d 1338
    , 1342 (11th Cir. 2005) (stating that issues not raised in
    party’s initial brief are deemed waived).
    47
    (“AEDPA”). Windom v. Sec’y, Dep’t of Corr., 
    578 F.3d 1227
    , 1247 (11th Cir.
    2009), cert. denied, — S. Ct. —, 
    78 U.S.L.W. 3579
     (U.S. Apr. 5, 2010) (No. 09-
    8930).
    Under AEDPA’s highly deferential standard for reviewing state court
    judgments, a federal court may not grant habeas relief on claims
    previously adjudicated on the merits by a state court unless the state
    court adjudication resulted in a decision that was (1) contrary to, or
    involved an unreasonable application of, clearly established Federal
    law, as determined by the Supreme Court of the United States; or (2)
    was based on an unreasonable determination of the facts in light of the
    evidence presented in the State court proceeding.

    28 U.S.C. § 2254

    III. DISCUSSION
    On appeal, DeYoung argues the district court erred in denying his § 2254
    petition because his trial counsel were ineffective in the penalty phase and
    therefore his appellate counsel was ineffective for not raising this issue in his new
    trial motion and on direct appeal.22 First we discuss the governing legal standards.
    22
    Both the state habeas court and the district court determined that DeYoung’s claims of
    ineffective trial counsel performance (except for trial counsel’s failure to call Butler, Albright,
    and Fisher as witnesses) were procedurally barred because appellate counsel Wilson had not
    raised them in the new trial motion and on direct appeal. Those courts alternatively denied
    DeYoung’s trial counsel claims on the merits. Although an alternative merits holding will not
    obviate a procedural bar, Philmore v. McNeil, 
    575 F.3d 1251
    , 1260 (11th Cir. 2009), cert.
    denied, 
    130 S. Ct. 1884
     (U.S. Mar. 22, 2010), we find it easier not to address the procedural bar
    issue here because: (1) DeYoung points out that Wilson was representing him at the new trial
    and direct appeal stage where he had a constitutional right to counsel and argues Wilson’s
    ineffectiveness is cause to excuse the procedural bar; and (2) to determine whether Wilson
    rendered ineffective assistance in omitting the ineffective trial counsel claims in the motion for
    new trial or on direct appeal, we would review the merits of the omitted claims. 
    Id. at 1264-65
    .
    Rather than wade through these complexities, we discuss the merits of DeYoung’s trial counsel
    48
    A.     Ineffective Assistance of Counsel
    Ineffective assistance of counsel claims are governed by the two-pronged
    test set forth in Strickland v. Washington, 
    466 U.S. 668
    , 
    104 S. Ct. 2052
     (1984),
    under which a defendant must show both (1) “that counsel’s performance was
    deficient,” and (2) “that the deficient performance prejudiced the defense.”
    Strickland, 
    466 U.S. at 687
    , 
    104 S. Ct. at 2064
    .
    As to counsel’s performance, “the Federal Constitution imposes one
    general requirement:       that counsel make objectively reasonable
    choices.” Bobby v. Van Hook, 558 U.S. —, 
    130 S. Ct. 13
    , 17, 
    175 L. Ed.2d 255
     (2009) (quotation marks omitted). Thus, to establish
    deficient performance, a defendant must show that his counsel’s
    conduct fell “‘below an objective standard of reasonableness’ in light
    of ‘prevailing professional norms’” at the time the representation took
    place. 
    Id. at 16
     (quoting Strickland, 
    466 U.S. at 688
    , 
    104 S. Ct. at 2064-65
    ). In assessing the reasonableness of counsel’s performance,
    courts must “indulge a strong presumption that counsel’s conduct falls
    within the wide range of reasonable professional assistance; that is,
    the defendant must overcome the presumption that, under the
    circumstances, the challenged action might be considered sound trial
    strategy.” Strickland, 
    466 U.S. at 689
    , 
    104 S. Ct. at 2065
     (quotation
    marks omitted).         “[S]trategic choices made after thorough
    investigation of law and facts relevant to plausible options are
    virtually unchallengeable; and strategic choices made after less than
    complete investigation are reasonable precisely to the extent that
    reasonable professional judgments support the limitations on
    investigation.” 
    Id. at 690-91

    of a capital trial, “hindsight is discounted by pegging adequacy to ‘counsel’s
    perspective at the time’ investigative decisions are made, and by giving a ‘heavy
    measure of deference to counsel’s judgments.’” Rompilla v. Beard, 
    545 U.S. 374
    ,
    380-81, 
    125 S. Ct. 2456
    , 2462 (2005) (citation omitted). Counsel has “no absolute
    duty to investigate particular facts or a certain line of defense,” although in some
    circumstances, “a complete failure to investigate may constitute deficient
    performance of counsel.” Parker v. Sec’y for the Dep’t of Corr., 
    331 F.3d 764
    , 787
    (11th Cir. 2003); see also Housel v. Head, 
    238 F.3d 1289
    , 1294 (11th Cir. 2001)
    (noting that a “failure to investigate can be deficient performance in a capital case
    when counsel totally fails to inquire into the defendant’s past or present behavior
    or life history”). However, “counsel need not always investigate before pursuing
    or not pursuing a line of defense. . . . [C]ounsel is not required to pursue every path
    until it bears fruit or until all hope withers.” Chandler v. United States, 
    218 F.3d 1305
    , 1318 (11th Cir. 2000) (en banc) (quotation marks omitted).
    The prejudice prong requires a showing “that there is a reasonable
    probability that, but for counsel’s unprofessional errors, the result of the
    proceeding would have been different.” Strickland, 
    466 U.S. at 694
    , 
    104 S. Ct. at 2068
    . For penalty-phase ineffectiveness claims, the prejudice question “is whether
    there is a reasonable probability that, absent the errors, the sentencer . . . would
    50
    have concluded that the balance of aggravating and mitigating circumstances did
    not warrant death.” 
    Id. at 695
    , 
    104 S. Ct. at 2069
    .
    In considering whether prejudice exists, courts must look at all the

    DeYoung raises a host of alleged deficiencies in his trial counsel’s
    performance, which we divide into three categories: (1) investigation and
    presentation of evidence of DeYoung’s family background and social history; (2)
    investigation, preparation, and presentation of mental health experts and evidence;
    and (3) implementation of trial counsel’s chosen penalty-phase strategies of
    residual doubt and mercy pleas from DeYoung’s family members.
    B.    Performance Prong: Family Background/Social History
    DeYoung contends his trial counsel Jones and O’Brien were ineffective for
    not adequately investigating and presenting evidence of DeYoung’s family
    background and social history. The state habeas court’s conclusion that DeYoung
    did not satisfy the performance prong of the ineffective assistance test is not
    contrary to clearly established federal law, does not involve an unreasonable
    51
    application of clearly established federal law, and is not based on an unreasonable
    determination of the facts in light of the evidence presented in the state court
    proceeding.
    First, Jones and O’Brien conducted an extensive investigation into possible
    mitigation evidence. Both attorneys interviewed potential witnesses. O’Brien
    traveled to Iowa, Ohio, and Michigan to talk to members of DeYoung’s family.
    Trial counsel retained investigator Stellmack and mitigation specialist Leonard.
    Stellmack subpoenaed DeYoung’s school and work records and compiled a list of
    more than forty possible mitigation witnesses, including DeYoung’s relatives,
    fellow church members, co-workers, friends, neighbors, and college and high
    school teachers. Someone from the defense team tried to contact every person on
    the list.23 DeYoung’s counsel argues that some evidence suggests the possibility
    that DeYoung might have been incestuously abused. What counsel ignores is that
    neither DeYoung, nor anyone else for that matter, ever testified that DeYoung was
    abused by either parent.
    Second, after having DeYoung’s mental health evaluated and interviewing
    numerous possible mitigation witnesses, trial counsel made strategic choices that
    23
    DeYoung argues that Jones and O’Brien “exaggerated” the extent of their discussions
    with DeYoung’s family. However, after reviewing the state court record, we conclude that the
    state habeas court’s findings on the extent of counsel’s investigation were not unreasonable in
    light of the evidence presented. See 
    28 U.S.C. § 2254
    (d)(2).
    52
    shaped the course of the final preparation. Before Jones was appointed to represent
    DeYoung, defense counsel’s penalty-phase strategy was “to have the psychiatrist
    talk about parricide and the dysfunction in the family in situations like this.” But
    when Jones joined the defense team as lead counsel, he took a different approach.
    Jones’s penalty-phase strategy was two-fold: to argue residual doubt and to call
    family members to plead for a merciful sentence. Jones believed the testimony of
    DeYoung’s family members would be particularly compelling because they were
    also related to the murdered victims in the case:
    You know, when you have got the family of the victims . . . coming in
    and asking the jury to spare their grandson’s life, I don’t know how
    much more compelling mitigation evidence you can get. . . .
    . . . I don’t know what else we could have presented . . . that
    would have been as good as that.
    Jones testified that “we went with what we thought would work at the time.” Trial
    counsel investigated several avenues of potential mitigation, but Jones wanted to
    avoid a mitigation approach that would involve “trying to trash [DeYoung’s]
    parents” because it might alienate the grandparents, whom Jones saw as potentially
    the most valuable witnesses.24
    Third, as the state habeas court found, many of the witnesses trial counsel
    24
    Moreover, as DeYoung’s parents and sister were the victims in the case, and his brother
    an intended victim, it is highly possible that a mitigation strategy that included evidence critical
    of DeYoung’s family and upbringing might have alienated the jury and hurt his cause.
    53
    contacted, including several who later furnished affidavits to state habeas counsel,
    were reluctant to testify at trial. After interviewing potential witnesses, Stellmack
    told O’Brien that “no one is exactly jumping at the idea of testifying on
    [DeYoung’s] behalf.” Stellmack testified, “People were pretty reluctant to even
    become involved or be associated with the case.”
    Even DeYoung’s grandparents were initially reluctant to testify. Nathan
    DeYoung never returned Stellmack’s calls, and Nathan’s girlfriend told Stellmack
    that Nathan had no interest in testifying. DeYoung’s minister, Chris Devos, was
    “hesitant to discuss a lot of details,” and informed Stellmack only “what you would
    expect from a pastor,” that is, that the DeYoungs “attended his church, they came
    to church on a regular basis, they seemed like a nice family.” Stellmack tried to
    interview DeYoung’s co-workers, but except for Kathy Albright, they refused to
    talk to him. Stellmack testified that “it was really difficult to find anyone, either in
    the church group or in the neighborhood[,] that could really shed a lot of light on
    the family dynamics of the DeYoung family.”
    Moreover, some of the witnesses who eventually provided affidavits to state
    habeas counsel had information that was harmful. For example, there was
    evidence that DeYoung sold marijuana at the Burger King where he worked, and
    Jones and O’Brien were hesitant to call DeYoung’s co-workers who might be able
    54
    to testify to that. And O’Brien was concerned that if DeYoung’s college professors
    testified about a decline in DeYoung’s academic performance around the time of
    the murders, the jury might find that testimony “suggestive of the fact that
    something was going on.” Daphne Collins told defense counsel that DeYoung told
    her he hated his parents and wanted them dead, and Cooper Etheridge told defense
    counsel he was not surprised by news of the murders because DeYoung had
    mentioned killing his parents and, in fact, said that “he wanted to kill everybody.”
    Given the record in this case, the state habeas court’s decision that
    DeYoung’s trial counsel’s performance was not deficient is consistent with
    established Supreme Court precedent. Counsel investigated different lines of
    mitigation and then made a strategic choice to employ residual doubt and family
    plea for mercy approaches in the penalty phase. Again, “strategic choices made
    after thorough investigation of law and facts relevant to plausible options are
    virtually unchallengeable; and strategic choices made after less than complete
    investigation are reasonable precisely to the extent that reasonable professional
    judgments support the limitations on investigation.” Strickland, 
    466 U.S. at
    690-
    91, 
    104 S. Ct. at 2066
    . Under the circumstances, counsel’s choices, and their
    investigation, fell well within “the wide range of professionally competent
    assistance.” 
    Id. at 690
    , 
    104 S. Ct. at 2066
    .
    55
    DeYoung’s attempts to analogize this situation to Wiggins v. Smith, 
    539 U.S. 510
    , 
    123 S. Ct. 2527
     (2003), and Williams v. Taylor, 
    529 U.S. 362
    , 
    120 S. Ct. 1495
     (2000), are unavailing. In Wiggins, trial counsel performed no investigation
    into the defendant’s personal history other than reading a one-page summary in the
    presentence investigation report (“PSI”) and obtaining department of social
    services (“DSS”) records. Wiggins, 
    539 U.S. at 523-24
    , 
    123 S. Ct. at 2536
    .
    Moreover, Wiggins’s counsel did not investigate Wiggins’s childhood, even
    though: (1) the PSI noted Wiggins’s “misery as a youth,” quoted Wiggins’s own
    description of his background as “disgusting,” and observed that Wiggins spent
    most of his life in foster care; and (2) the DSS records revealed Wiggins’s mother
    “was a chronic alcoholic; Wiggins was shuttled from foster home to foster home
    and displayed some emotional difficulties while there; he had frequent, lengthy
    absences from school; and, on at least one occasion, his mother left him and his
    siblings alone for days without food.” 
    Id. at 523-25
    , 
    123 S. Ct. at 2536-37
    .
    Wiggins’s counsel discovered no evidence suggesting that further investigation
    would be fruitless or a mitigation case counterproductive, and the record showed
    that counsel’s “failure to investigate thoroughly resulted from inattention, not
    reasoned strategic judgment.” 
    Id. at 525-26
    , 
    123 S. Ct. at 2537
    . And in Williams,
    the defendant’s trial counsel did not begin to prepare for the penalty phase until a
    56
    week before trial, and “failed to conduct an investigation that would have
    uncovered extensive records graphically describing Williams’ nightmarish
    childhood, not because of any strategic calculation but because they incorrectly
    thought that state law barred access to such records.” Williams, 
    529 U.S. at 395
    ,
    
    120 S. Ct. at 1514
    .
    The present case is easily distinguishable from Wiggins and Williams, as
    Jones and O’Brien conducted an extensive investigation and made express strategic
    choices. This case is more akin to Bobby v. Van Hook, 
    130 S. Ct. 13
    , 19 (2009),
    in which the Supreme Court recognized a point of diminishing returns in the broad
    search for mitigating evidence:
    Despite all the mitigating evidence the defense did present, Van
    Hook and the Court of Appeals fault his counsel for failing to find
    more. What his counsel did discover, the argument goes, gave them
    “reason to suspect that much worse details existed,” and that suspicion
    should have prompted them to interview other family members–his
    stepsister, two uncles, and two aunts–as well as a psychiatrist who
    once treated his mother, all of whom “could have helped his counsel
    narrate the true story of Van Hook’s childhood experiences.” But
    there comes a point at which evidence from more distant relatives can
    reasonably be expected to be only cumulative, and the search for it
    distractive from more important duties. The ABA Standards
    prevailing at the time called for Van Hook’s counsel to cover several
    broad categories of mitigating evidence, which they did. And given all
    the evidence they unearthed from those closest to Van Hook’s
    upbringing and the experts who reviewed his history, it was not
    unreasonable for his counsel not to identify and interview every other
    living family member or every therapist who once treated his parents.
    This is not a case in which the defendant’s attorneys failed to act
    57
    while potentially powerful mitigating evidence stared them in the
    face, cf. Wiggins, 
    539 U.S., at 525
    , 
    123 S. Ct. 2527
    . . . . It is instead a
    case, like Strickland itself, in which defense counsel’s “decision not to
    seek more” mitigating evidence from the defendant’s background
    “than was already in hand” fell “well within the range of
    professionally reasonable judgments.”

    C.    Performance Prong: Mental Health Evidence
    DeYoung also argues Jones and O’Brien were ineffective in failing to
    adequately investigate mental health issues, prepare mental health experts, and
    present mental health expert testimony. The state habeas court’s denial of this
    claim is not contrary to, or an unreasonable application of, Supreme Court
    precedent. Nor is it based on an unreasonable determination of the facts.
    First, almost all of the evidence that DeYoung now claims his mental health
    experts needed was available to DeYoung himself, yet DeYoung did not reveal it
    to his counsel or the two pretrial mental health experts, Drs. Messer and Shaffer.
    “In evaluating the reasonableness of a defense attorney’s investigation, we weigh
    heavily the information provided by the defendant.” Newland v. Hall, 
    527 F.3d 1162
    , 1202 (11th Cir. 2008), cert. denied, 
    129 S. Ct. 1336
     (2009). Indeed, a
    defense attorney “does not render ineffective assistance by failing to discover and
    develop evidence of childhood abuse that his client does not mention to him.” 
    Id.
    Here, there is no evidence that DeYoung mentioned to his trial or appellate counsel
    58
    or to any mental health experts (before trial or even afterward) that he had any
    family history of mental illness or that there was significant internal strife or
    dysfunction in his family. Two mental health experts thoroughly evaluated
    DeYoung in person before trial and did not diagnose him with the mental
    infirmities DeYoung now claims he suffered. Importantly, to date DeYoung has
    never indicated he suffered any sexual or physical abuse, nor has anyone witnessed
    such abuse of DeYoung.
    Second, as with the family background and social history evidence,
    DeYoung’s counsel performed a reasonable investigation into mental health issues.
    Jones and O’Brien retained Dr. Messer and Dr. Shaffer, who each conducted an
    independent evaluation supported by document review and one or more in-person
    clinical interviews. Jones and O’Brien met with Drs. Messer and Shaffer to
    discuss their diagnoses before deciding whether to present a mental health-based
    defense. Jones and O’Brien decided not to present mental health evidence at the
    penalty phase because, as Jones testified, they determined “it was not helpful.”
    Although DeYoung now contends that trial and appellate counsel should
    have provided more family information to the mental health experts, and that that
    information would have changed their diagnoses, the state habeas court’s
    conclusion that trial counsel reasonably investigated DeYoung’s family
    59
    background and social history is consistent with clearly established federal law and
    is not unreasonable in light of the facts. This is especially accurate given that
    DeYoung never gave any indication of sexual or physical abuse. Given the many
    witnesses trial counsel or the investigator interviewed, the mere fact that additional
    family and social history witnesses have now been discovered does not make trial
    or appellate counsel ineffective. The record also supports the state habeas court’s
    findings that a number of the witnesses who gave affidavits to habeas counsel were
    not as forthcoming prior to trial and that a significant portion of the testimony in
    the affidavits was inadmissible (such as for being pure hearsay).
    Third, DeYoung does not argue that his trial counsel should have presented
    mental health expert testimony as to Dr. Messer’s and Dr. Shaffer’s original
    diagnoses of borderline personality disorder and narcissistic personality disorder.
    He argues only that his trial and appellate counsel should have discovered and
    presented evidence that DeYoung had schizotypal personality disorder and
    dysthymia (the subsequent diagnosis). However, even if trial counsel had
    presented such testimony, it would have opened the door to harmful evidence, such
    as: (1) the original diagnoses of Dr. Messer and Dr. Shaffer, which disorders have
    been found not to be mitigating, see, e.g., Reed, 
    593 F.3d at 1248
     (concluding
    psychologist’s diagnosis of defendant with antisocial personality disorder and
    60
    narcissistic personality disorder was harmful instead of mitigating); (2) Dr. Sachy’s
    testimony that DeYoung had no personality disorder and was malingering (which
    would have reinforced the State’s picture of DeYoung as having a cunning and
    manipulative criminal mind); and (3) other characteristics of schizotypal
    personality disorder itself, including peculiar or eccentric behavior and lack of
    close friends or confidants other than first-degree relatives (accentuating that
    DeYoung lacked close friends and chose to kill for financial gain even those few
    persons close to him).
    Fourth, DeYoung provides no evidence indicating trial counsel had a
    reasonable basis to suspect, at the time, that providing Dr. Messer and Dr. Shaffer
    with more background information on DeYoung was likely to change their
    diagnoses. See Wiggins, 
    539 U.S. at 523
    , 
    123 S. Ct. at 2536
     (noting that inquiry
    into reasonableness of counsel’s performance “includes a context-dependent
    consideration of the challenged conduct as seen from counsel’s perspective at the
    time,” and that “[e]very effort [must] be made to eliminate the distorting effects of
    hindsight” (alterations in original) (quotation marks omitted)); see also Reed, 
    593 F.3d at 1242
     (“[T]he mere fact a defendant can find, years after the fact, a mental
    health expert who will testify favorably for him does not demonstrate that trial
    counsel was ineffective for failing to produce that expert at trial.”).
    61
    D.    Performance Prong: Penalty Phase Strategy
    DeYoung makes several allegations of deficient performance by his trial
    counsel in implementing their chosen penalty-phase strategy of presenting pleas
    for mercy from DeYoung’s family members and arguing residual doubt.
    Specifically, DeYoung argues trial counsel performed in an objectively
    unreasonable manner by choosing: (1) to call grandmother Letha DeYoung to
    testify; (2) not to call Nathan DeYoung to testify; (3) not to present letters from
    DeYoung’s extended family members; (4) not to adequately attack Hagerty as a
    violent man who had a greater role in the murders than he admitted; and (5) not to
    refute the State’s footlocker evidence. Having reviewed DeYoung’s arguments
    and the record, we conclude that, other than the claim regarding Nathan DeYoung,
    each of DeYoung’s arguments as to the alleged deficiency of trial counsel’s
    penalty-phase presentation constitutes an improper attempt to second-guess a
    reasonable strategic choice of trial counsel. See Rhode v. Hall, 
    582 F.3d 1273
    ,
    1284 (11th Cir. 2009) (“Which witnesses, if any, to call, and when to call them, is
    the epitome of a strategic decision, and it is one that we will seldom, if ever,
    second guess.” (brackets omitted)), cert. denied, 
    78 U.S.L.W. 3714
     (U.S. Jun. 7,
    2010). This strategy was reasonable because: (1) having the parents of the
    murdered victims plead for the defendant’s life is powerful mitigating testimony;
    62
    and (2) as we have noted before in several cases, “creating lingering or residual
    doubt over a defendant’s guilt is not only a reasonable strategy, but is perhaps the
    most effective strategy to employ at sentencing.” Ward v. Hall, 
    592 F.3d 1144
    ,
    1170 (11th Cir. 2010) (quotation marks and brackets omitted). The state habeas
    court’s rejection of these claims was not contrary to or based on an unreasonable
    application of clearly established federal law.25
    As to not calling Nathan to testify in the penalty phase, the state habeas court
    found that Jones and O’Brien made reasonable efforts to contact Nathan to secure
    his testimony, but Nathan did not return their calls, indicating he “had no intention
    of assisting the defense in Petitioner’s case.” The evidence in the state habeas
    proceeding amply supported this finding.
    E.     Prejudice Prong
    Even if DeYoung could show deficient performance by his trial or appellate
    25
    DeYoung argues trial counsel performed deficiently in calling Letha DeYoung because
    her testimony introduced prejudicial, damaging evidence of DeYoung’s alleged Satanism. In
    their penalty-phase closing arguments, neither the State nor the defense mentioned Satanism or
    Letha DeYoung’s opinion that it drove DeYoung to commit the murders. Further, there was
    already some evidence of Satanism in the trial. In DeYoung’s police interview, a recording of
    which was played for the jury, DeYoung was asked whether he was a Satanist or read books on
    Satanism. DeYoung admitted he “ha[d] some books on witchcraft and stuff in [his] room” but,
    as to his belief in Satan, stated, “I figure evil will probably win in the end. But I don’t really
    have a preference. I mean, I don’t strive for either one. I just kind of take things as they come.”
    In any event, it was not objectively unreasonable for trial counsel to decide that the risk
    associated with calling Letha DeYoung to testify was outweighed by the potential benefit, given
    her fervent desire that DeYoung not be executed and that she was the mother of one murdered
    victim and the grandmother of another murdered victim.
    63
    counsel, he must still show prejudice, that is, that “there is a reasonable probability
    that, absent the errors, the [jury] . . . would have concluded that the balance of
    aggravating and mitigating circumstances did not warrant death.” Strickland, 
    466 U.S. at 695
    , 
    104 S. Ct. at 2069
    . The state habeas court concluded DeYoung did not
    satisfy his prejudice burden. This conclusion is not contrary to established federal
    law, an unreasonable application of established federal law, or based on an
    unreasonable determination of the facts in light of the evidence.
    The weight of aggravation evidence in this case is immense. DeYoung
    stands convicted of a carefully planned and premeditated triple murder of his
    mother, father, and fourteen-year-old sister. The method of killing was a study in
    brutality. Gary and Kathryn DeYoung were attacked in their beds. Each victim
    suffered more than three dozen slashing, stabbing, cutting, and chopping wounds.
    In some areas of the victims’ bodies, such as the back of Sarah’s neck, the knife
    wounds overlapped so much it was impossible to determine how many individual
    wounds they suffered. Many of the wounds were inflicted while the victims were
    lying down and trying to move around or roll away. Sarah, Gary, and Kathryn
    DeYoung died of blood loss, shock, and interrupted heart functioning.
    The total mitigating evidence pales in comparison. Although the categories
    of mitigating evidence DeYoung argues should have been presented (e.g., a
    64
    different mental illness, emotionally distant and oppressive upbringing, and sexual
    abuse) seem substantial, the actual evidence he submits to comprise those
    categories is weak or nonexistent. For example, there is no evidence DeYoung
    was sexually abused. DeYoung himself never said so, nor did he report it to any of
    the four doctors who examined him. Nor has Nathan ever even implied, much less
    stated, that any sexual abuse occurred. DeYoung offers no evidence of sexual
    abuse.
    As to mental illness, DeYoung’s mental health expert Dr. Sultan opined that
    DeYoung suffers from schizotypal personality disorder and dysthymia, which
    compromised DeYoung’s judgment and ability to function interpersonally. The
    state habeas court wholly discredited Dr. Sultan’s testimony. In any event, this
    diagnosis was countered not only by the testimony of the State’s mental health
    expert, Dr. Sachy (who said DeYoung did not have these disorders), but also by,
    inter alia, the facts that: (1) Dr. Sultan’s evaluation of DeYoung took place seven
    years after the murders and five years after DeYoung’s trial; (2) Dr. Messer and
    Dr. Shaffer both evaluated DeYoung before trial and neither diagnosed him with
    these disorders or found that he had any significant psychiatric defenses; and (3)
    before the murders, DeYoung was capable of functioning well enough to attend
    college, to be a manager at Burger King, and to have relationships with friends and
    65
    girlfriends. And, as explained earlier, such mental health evidence would have
    opened the door to harmful testimony which may well have eliminated any
    mitigating weight in the overall equation.
    As to the testimony about the DeYoung family’s social dysfunction,
    DeYoung proffered evidence, from various acquaintances and other sources,
    suggesting that the DeYoungs were socially inept, private people who showed little
    emotion; that Gary DeYoung was hyper-rational, judgmental, authoritarian,
    obsessive, and emotionally distant; that Kathryn DeYoung was isolated and
    submissive; that Gary and Kathryn DeYoung showed DeYoung little affection, and
    afforded him little freedom or control; and that the DeYoungs’ home was
    extremely cluttered. We note that DeYoung himself never said anything to
    confirm these opinions. DeYoung in fact said he missed his parents. Other
    witnesses contradicted this picture painted by the habeas affidavits. In any event,
    all of the family dysfunction testimony, even taken together and credited as true, is
    weak and a far cry from the horrific childhood circumstances that have been held
    sufficient to satisfy the prejudice prong in a capital case. See Rompilla v. Beard,
    
    545 U.S. at 391-92
    , 
    125 S. Ct. at 2468-69
     (stating that overlooked mitigation
    evidence included evidence that Rompilla’s parents were alcoholics, his father
    frequently beat his mother and bragged about his infidelity, his father beat
    66
    Rompilla and locked him and his brother in an excrement-filled dog pen, Rompilla
    slept in an unheated attic, and he was given no clothes and went to school in rags);
    Wiggins, 
    539 U.S. at 534-35
    , 
    123 S. Ct. at 2542
     (noting evidence, inter alia, of
    “severe privation and abuse in the first six years of . . . life,” and “physical torment,
    sexual molestation, and repeated rape during . . . subsequent years in foster care”);
    Williams, 
    529 U.S. at 395
    , 
    120 S. Ct. at 1514
     (finding counsel failed to put on
    graphic evidence of defendant’s “nightmarish childhood” that included his parents’
    imprisonment for criminal neglect of him and his siblings, his severe and frequent
    beatings by his father, and his commitment to an abusive foster home).
    Having carefully reviewed the record, we conclude that the state habeas
    court reasonably found that even if DeYoung had offered, and the state trial court
    had admitted, all the mitigation evidence DeYoung submitted in the state habeas
    proceeding, it would not have been sufficient to raise a reasonable probability of a
    different sentence in light of the strong evidence in aggravation. DeYoung
    therefore has not satisfied the prejudice prong of the ineffective-counsel test.
    IV. CONCLUSION
    We affirm the district court’s denial of DeYoung’s § 2254 petition.
    AFFIRMED.
