    OPINION
    _________________
    CLAY, Circuit Judge. Petitioner, a convicted murderer and rapist sentenced to
    death in Tennessee, sought a writ of habeas corpus pursuant to 28 U.S.C. § 2254(d). The
    district court denied his petition in its entirety, but granted Petitioner a certificate of
    appealability on one claim—that the state improperly excluded mitigation evidence at
    his resentencing hearing. This Court expanded the certificate to cover four additional
    claims. Petitioner now appeals on those issues, which are the prosecutor’s misconduct
    in rebuttal at Petitioner’s resentencing; ineffective assistance of counsel at his
    resentencing; suppression of favorable, material evidence in violation of Brady v.
    Maryland, 
    373 U.S. 83
    (1963); improper review of the exclusion of mitigation evidence
    at the resentencing; and unconstitutional vagueness in the Tennessee aggravating factor
    applied at resentencing.
    For the reasons set forth in this opinion, we AFFIRM the district court with
    respect to all of Petitioner’s claims except for his claims of prosecutorial misconduct and
    ineffective assistance of counsel, REVERSE the district court with respect to those two
    claims and GRANT a conditional writ of habeas corpus.
    BACKGROUND
    I.       Factual Background1
    Captain Patrick Smith and his wife, Captain Rosemary Smith (“Patrick” and
    “Rosemary”) were officers in the United States Army Nurse Corps, stationed at Fort
    Campbell, Kentucky and living at 352 Hampshire Drive in Clarksville, Tennessee. On
    January 9, 1987, when neither Patrick nor Rosemary reported for duty, Major Kathleen
    Campbell and a sergeant drove to the Smiths’ home, and arrived there at about 11:00
    1
    Because the facts underlying each of Petitioner’s claims are unrelated, or from different
    procedural phases of the case, some facts are discussed in the section on procedural history or in the
    section that addresses the particular claim to which they are relevant.
    No. 10-5759            Cauthern v. Colson                                                         Page 3
    a.m. They noticed that both of the Smiths’ cars were in the garage, and the glass on the
    backdoor had been broken from the outside. Major Campbell went to a neighbor’s house
    and phoned the police.
    When the police arrived, they found evidence of forcible entry, and the house
    ransacked. They also found the Smiths dead in separate bedrooms, each apparently
    killed by strangulation. Officer John Nichols of the Clarksville Police Department
    (“CPD”) was one of the officers on the scene. Ronnie M. Cauthern (“Petitioner”), and
    Brett Patterson (“Patterson”) were ultimately arrested for the murders, along with Eric
    Barbee (“Barbee”), who was a friend of Patterson’s, though Barbee was never implicated
    in the murders. Patterson and Cauthern were convicted of the murders, as well as other
    crimes related to the incident. The Tennessee Court of Criminal Appeals entered the
    following findings of fact:2
    [T]he body of Patrick Smith lying face down on the bed in the master
    bedroom, facing 90 degrees counter clockwise from his sleeping position,
    and wrapped in the top sheet. He had been strangled to death, apparently
    with a length of 880 military cord. The bed was broken and tilted
    indicating a violent struggle had taken place.
    Cauthern v. State, 
    145 S.W.3d 571
    , 580 (Tenn. Crim. App. 2004) (quoting State v.
    Cauthern, 
    778 S.W.2d 39
    , 40 (Tenn. 1989)).
    The body of Rosemary Smith was discovered in another bedroom; her
    underclothes were next to her body and her nightgown was in the corner
    of the room. A scarf had been tied around her neck and knotted, with a
    small vase inserted between the nape of the neck and the knot, creating
    a tourniquet . . . Credit cards, electronic gear and a videocassette recorder
    appeared to be missing from the house. Police found costume jewelry in
    the house, but no jewelry of value.
    
    Id. (quoting State
    v. Cauthern, 
    967 S.W.2d 726
    , 730 (Tenn. 1998)).

    Under 28 U.S.C. § 2254(e)(1), “a determination of a factual issue made by a State court shall
    be presumed to be correct. The applicant shall have the burden of rebutting the presumption of correctness
    by clear and convincing evidence.” Petitioner has not presented evidence that demonstrates any dispute
    over the facts of the underlying incident, and accordingly, these facts are presumed correct. Thompson v.
    Bell, 
    580 F.3d 423
    , 434 (6th Cir. 2009). As is discussed more fully in the section on procedural history,
    there are two relevant state court decisions: the Tennessee Supreme Court’s decision in 1998, denying
    Petitioner’s direct appeal of his resentencing hearing, and the Tennessee Court of Criminal Appeal’s
    decision in 2004, which denied Petitioner’s collateral challenges.
    No. 10-5759        Cauthern v. Colson                                                 Page 4
    The police found the telephone line had been cut near its entry into the
    outside wall of the house. A shoe print was found on the back door that
    matched Patterson’s shoe. In a statement that he gave police he admitted
    kicking the back door once or twice, but said it would not open so they
    obtained a hammer and broke the pane of glass nearest the door knob to
    gain entry. The house was ransacked, chest of drawers open, luggage
    and clothing scattered about. In the master bedroom, the police found a
    piece of paper upon which was written defendant Cauthern’s name,
    address and telephone number. Rosemary Smith’s sister testified she was
    familiar with both her sister’s and her brother-in-law’s handwriting and
    the information about Cauthern was not written by either of them. The
    cumulative evidence [established] that defendant and the Smiths had
    been acquainted for approximately a year at the time of the murders, that
    he had performed some work on Patrick’s Mercedes and perhaps some
    additional work at their home, although he said in one of his statements
    that he had never been inside their home until the evening of 8 January
    1987.
    
    Id. (quoting Cauthern,
    778 S.W.2d at 40.)
    James Phillip Andrew testified [at both trials] that he was with the
    defendant, Ronnie Cauthern, and Brett Patterson shortly after the
    offenses. While watching television, they all saw an account of the
    Smiths’ murders in which a reward was offered for information.
    Cauthern told Andrew that he had worked for the Smiths in the past and
    that he broke into their home and made the woman get into the closet,
    while he and Patterson strangled the man. Cauthern told Andrew that he
    raped the woman once and that he had stolen a wedding ring, a VCR, and
    some credit cards . . . .
    Joe Denning, Andrew’s roommate, also testified that Ronnie Cauthern
    admitted his role in the killings. Cauthern told Denning that he had cut
    the telephone lines to the house, had broken in through the back door,
    had shined flashlights in the victims’ faces in order to wake them, and
    had placed Rosemary Smith in a closet. He admitted to Denning that he
    had raped the woman and poured wine coolers over her, and then
    attempted to kill her. He said he tried to strangle the woman by tying a
    scarf around her neck, but did not have the strength to kill her, so he used
    the vase to create a tourniquet....
    Cauthern’s former girlfriend, Jackie Pigue, testified that on Thursday
    night, January 8, 1987, Cauthern and Patterson were “solemn” and
    “quiet.” The next day Cauthern gave her a watch and a wedding ring.
    He told her that someone owed him money and he was holding the items
    No. 10-5759      Cauthern v. Colson                                                 Page 5
    as collateral. When she later saw a news report regarding the murders
    and Cauthern’s arrest, she went to the police and gave them the jewelry.
    Cauthern and Patterson were arrested on January 12, 1987. Search
    warrants were obtained for Cauthern’s car and Patterson’s house.
    Among the items found were the victims’ credit cards, identification
    cards, receipts, checks and two key rings containing keys which unlocked
    the Smiths’ home and automobiles. The police also found two ski masks,
    several handguns, a roll of 880 military cord, and Patrick Smith’s jacket.
    Initially, Cauthern gave several statements to the police, all of which
    were admitted into evidence at the sentencing hearing. In the first
    statement, he denied knowing the Smiths or anything about the murders.
    In a later statement, which was recorded and transcribed, Cauthern
    admitted that he was in the Smiths’ home, but denied that he had raped
    or murdered anyone. Claiming that he and Mrs. Smith were having an
    affair, he contended that she had called and invited him to come to the
    Smith house and enter through the back door. He said that both he and
    Patterson had consensual sex with Mrs. Smith, and he denied that he
    participated in the murders, raped the victim, or removed any items from
    the house.
    [At the 1995 resentencing trial], Cauthern testified that he was nineteen
    years old at the time of the murders. He stated that he never knew his
    birth father and saw his birth mother approximately three times during
    his entire life. His birth mother died, and he was adopted by his maternal
    grandmother and step-grandfather who moved to Clarksville in 1973.
    The defendant attended Northeast High School, but dropped out to care
    for his grandmother who had Parkinson’s disease, so that his
    step-grandfather could continue to work. He was married at the age of
    eighteen and at the time of the hearing, had an eight-year-old son.
    Although he had divorced his son’s mother, he continued to see his son
    every three to five months. Since his incarceration he had remarried.
    His wife, who lived in Canada, was not at the hearing. He testified that
    he helps his parents by writing letters for them.
    Cauthern also said he had completed the Graduate Equivalency
    Examination and a paralegal course since being incarcerated, and he
    serves as a teacher’s aide to the unit prison teacher. He has achieved “A”
    status at Riverbend Maximum Security Institution for privilege purposes,
    which is the highest status available for a prisoner. He introduced letters
    of appreciation from a correctional officer and the prison teacher. A Unit
    Review Panel Hearing form containing positive comments concerning
    his behavior and attitude was also introduced. He makes extra money by
    drawing greeting cards and selling them to other prisoners. Charles
    Tracy, a teacher for the Department of Correction, testified that he chose
    No. 10-5759           Cauthern v. Colson                                                      Page 6
    Cauthern as a teacher’s aide because he gets along well with others and
    has good communication skills.
    
    Id. (quoting State
    v. 
    Cauthern, 967 S.W.2d at 730
    –31).
    II.      Procedural History
    Petitioner was indicted on February 3, 1987. The indictment had eight charges:
    first-degree felony murder for the death of Patrick, first-degree felony murder for the
    death of Rosemary, first-degree burglary, aggravated rape, rape, third-degree burglary,
    grand larceny, and armed robbery.3 Petitioner was tried by jury with Patterson in
    February 1988. On February 23, 1988, after about four hours of deliberations, the jury
    returned guilty verdicts on the murder, burglary, and aggravated rape charges.
    The penalty phase of the trial began that day and ended on February 25, 1988.
    The jury returned a sentence of death for Petitioner on both of the murder counts, and
    sentences of life imprisonment for Patterson on the murder charges. On March 18, 1988,
    Petitioner was formally sentenced to death for the two counts of felony murder, as well
    as forty years’ imprisonment on the aggravated rape count, and ten years’ imprisonment
    for the first-degree burglary. Petitioner filed his notice of appeal on May 20, 1988. The
    Tennessee Supreme Court4 affirmed the felony murder convictions but remanded the
    sentences of death because the trial court failed to suppress portions of Petitioner’s third
    statement to the police. The United States Supreme Court denied the petition for a writ
    of certiorari. Tennessee v. Cauthern, 
    495 U.S. 904
    (1990).
    Venue for the resentencing was transferred to Gibson County, Tennessee (from
    Montgomery County) because of concerns over publicity in the original venue. At
    Petitioner’s 1995 resentencing hearing, the jury heard testimony from Patrick’s mother,
    Constance Smith, about Patrick and Rosemary’s background and aspirations. The jury
    3
    The counts of third-degree burglary, grand larceny, and armed robbery were unrelated to the
    Smith murders and were not tried in the same trial.
    4
    Because this was a capital case, Petitioner had the right of direct review by the Tennessee
    Supreme Court, and therefore by-passed review by the Tennessee Court of Criminal Appeals. Cauthern
    v. 
    State, 145 S.W.3d at 579
    n.1.
    No. 10-5759           Cauthern v. Colson                                                       Page 7
    also heard testimony from Officer Nichols, about the crime scene, and from a doctor
    about the injuries sustained by the victims. Detective Cockarell testified that there had
    been a violent struggle. Other detectives testified as to statements given by Petitioner.5
    The final state witness was Andrew, who repeated his earlier testimony regarding
    Petitioner boasting of the rape. The defense called Charles Tracy, a teacher who worked
    with the Tennessee Department of Correction, who knew Petitioner because Petitioner
    worked as a teacher’s aide for him, and Petitioner himself testified. During rebuttal, the
    prosecutor gave an inflammatory speech, reproduced in the relevant section below,
    which Petitioner contends gives rise to a claim for habeas relief.
    At the conclusion of the resentencing hearing, Petitioner was sentenced to life
    in prison for the murder of Patrick, and to death for the murder of Rosemary. That
    sentence was affirmed by the Tennessee Court of Criminal Appeals on December 2,
    1996, and by the Tennessee Supreme Court on March 23, 1998. State v. Cauthern, 
    967 S.W.2d 726
    (Tenn. 1998). Certiorari to the United States Supreme Court was again
    denied on November 2, 1998. Cauthern v. State, 
    525 U.S. 967
    (1998). Petitioner filed
    a pro se petition for post-conviction relief in January 1999. He later amended that
    pleading with the assistance of counsel. That petition was denied after evidentiary
    hearings. The Tennessee Court of Criminal Appeals affirmed the lower court’s
    judgment in February 2004, and the Tennessee Supreme Court declined to hear
    Petitioner’s appeal in August 2004. During the post-conviction hearings:
    [T]he petitioner presented testimony from twelve witnesses. Three
    family members, two family friends, and the petitioner’s former wife
    testified about the petitioner’s upbringing and social history. The two
    attorneys who had previously represented the petitioner recounted their
    investigative efforts, pretrial preparation, and trial strategy on the
    petitioner’s behalf. Two former law enforcement officers testified to
    Brett Patterson’s prior criminal history and his suspected involvement in
    the rape and strangulation death of a teenage female in Los Alamos, New
    Mexico. An expert in clinical and forensic psychiatry testified about his
    evaluation of the petitioner and the resulting diagnosis. Last, the Deputy
    Consul General to the German Consulate in Atlanta, Georgia testified as
    5
    Some of the testimony at the sentencing was relevant only to claims that Petitioner no longer
    pursues, and has been omitted.
    No. 10-5759        Cauthern v. Colson                                                Page 8
    an expert on the subjects of German citizenship, the petitioner’s
    genealogy that could qualify him for German citizenship, and the
    requirements of the Vienna Convention when a German national is
    arrested in the United States. In rebuttal to the petitioner’s experts, the
    state presented testimony from a psychologist who had been retained by
    the prosecution to perform a forensic evaluation of the petitioner and
    from a senior counsel with a Washington, D.C. law firm whose practice
    focused on public and private international law. The petitioner did not
    testify in support of his bid for post-conviction relief.
    Cauthern v. State, 
    145 S.W.3d 571
    , 582–83 (Tenn. Crim. App. 2004).
    Petitioner, having been granted counsel, filed the instant petition on June 3, 2005,
    raising 27 claims for relief. The district court denied the petition in its entirety, on
    March 31, 2010, and declined to issue a certificate of appealability with respect to any
    of the claims. On May 28, 2010, the district court declined to amend its judgment, but
    did issue a certificate of appealability as to the question of “whether the Tennessee
    Supreme Court’s application of a harmless error test to the improper exclusion of
    mitigating evidence at the 1995 resentencing was contrary to, or involved an
    unreasonable application of, clearly established federal law.” (R. 180, Memorandum
    Opinion, May 28, 2010, at 1.) (Claim 2 in the petition)
    Upon Cauthern’s motion, this Court granted an expanded certificate of
    appealability on August 16, 2011. That certificate added the following issues to review:
    (a) “whether the prosecutor engaged in misconduct during closing argument at the
    resentencing hearing” (Claim 1); (b) “whether the State withheld favorable evidence in
    violation of Brady v. Maryland, 
    373 U.S. 83
    (1963), and its progeny” (Claim 4);
    (c) “whether trial counsel rendered Cauthern ineffective assistance at his 1995
    resentencing hearing” (Claim 5) and (d) whether the heinous, atrocious, or cruel
    aggravator weighed by the jury was unconstitutional. (Claim 7).
    No. 10-5759          Cauthern v. Colson                                                    Page 9
    DISCUSSION
    I.       Standard of Review
    Where a district court has denied a habeas petition, and issued a certificate of
    appealability, “we review the district court’s legal conclusions de novo and its factual
    findings for clear error.” Hanna v. Ishee, 
    694 F.3d 596
    , 605 (6th Cir. 2012) (citing Smith
    v. Mitchell, 
    567 F.3d 246
    , 255 (6th Cir. 2009)). The district court’s findings of fact are
    clearly erroneous when “we are left with the definite and firm conviction that a mistake
    has been committed.” United States v. Canipe, 
    569 F.3d 597
    , 600 (6th Cir. 2009) (citing
    United States v. Ellis, 
    497 F.3d 606
    , 611 (6th Cir. 2007)).
    II.      AEDPA6
    Under the Antiterrorism and Effective Death Penalty Act of 1996 (“AEDPA”),
    a federal court may not grant a writ of habeas corpus with respect to any claim
    adjudicated on the merits in state court unless the state adjudication:
    (1) resulted in a decision that was contrary to, or involved an
    unreasonable application of, clearly established federal law, as
    determined by the Supreme Court of the United States; or
    (2) resulted in a decision that 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(d). A federal court may not issue the writ “simply because it
    concludes in its independent judgment that the relevant state-court decision applied
    clearly established federal law erroneously or incorrectly. Rather, that application must
    also be unreasonable.” Williams v. Taylor, 
    529 U.S. 362
    , 411 (2000). “[C]learly
    established federal law, as determined by the Supreme Court of the United States” refers
    to the holdings, rather than dicta, of the decisions of the Supreme Court. Howes v.
    Fields, ___ U.S. ___, 132 S. Ct 1181, 1187 (2012) (quoting 
    Williams, 529 U.S. at 362
    ).
    6
    The petition was filed on June 3, 2005, which is after the effective date of AEDPA, and
    accordingly, AEDPA standards govern the petition. See Lindh v. Murphy, 
    521 U.S. 320
    , 326–27 (1997).
    No. 10-5759             Cauthern v. Colson                                                           Page 10
    A decision that is “contrary to” clearly established federal law occurs where “the
    state court arrives at a conclusion opposite to that reached by this Court on a question
    of law . . . [or] confronts facts that are materially indistinguishable from a relevant
    Supreme Court precedent and arrives at [the opposite] result.” 
    Williams, 529 U.S. at 405
    . Furthermore, an unreasonable application must be distinguished from an incorrect
    application. Harrington v. Richter, 562 U.S. ___, 
    131 S. Ct. 770
    , 785 (2011) (quoting
    
    Williams, 529 U.S. at 410
    ). A state court decision which is merely incorrect, rather than
    unreasonable, is still entitled to deference by a federal court in a habeas proceeding. 
    Id. As a
    result, the more general the rule, the greater the leeway accorded to a state court’s
    decision under federal habeas review. 
    Id. at 786.
    Under AEDPA this Court reviews the last reasoned state court decision. See
    Cullen v. Pinholster, 563 U.S. ___, 
    131 S. Ct. 1388
    , 1402 (2011) (“Section 2254(d)
    applies even where there has been a summary denial.”). Even when a state court does
    not provide significant analysis, this Court must show significant respect to state court
    decisions:
    Even in the case of a summary denial, when the state court has not fully
    explained the rationale for its decision, the reviewing “habeas court must
    determine what arguments or theories could have supported the state
    court’s decision; and then it must ask whether it is possible [that]
    fairminded jurists could disagree that those arguments or theories are
    inconsistent with the holding in a prior [Supreme Court] decision.”
    Gagne v. Booker, 
    680 F.3d 493
    , 514 (6th Cir. 2012) (en banc) (quoting 
    Pinholster, 131 S. Ct. at 1402
    ).7
    7
    In this case, the question of what constitutes the last reasoned state court decision is slightly
    more complicated than in an ordinary habeas proceeding. Petitioner seeks federal habeas review of some
    claims that were presented to the Tennessee Court of Criminal Appeals during his collateral challenge to
    his conviction and sentence, as well as to claims that were only raised during his direct appeals. Neither
    party claims that Petitioner failed to exhaust any of his claims, and so the last reasoned state court decision
    may be different with respect to certain claims, depending on the availability of state collateral relief.

    III.    Prosecutorial Misconduct
    A.      The Prosecutor’s Misconduct at the Resentencing Hearing
    During closing arguments at the 1995 resentencing hearing Assistant Attorney
    General Steve Garrett gave a rebuttal that included the following language:
    Yes, we are asking for the death penalty. Why? Why should Ronnie
    Cauthern die? I once heard an interpretation of the Lord’s Prayer.
    “Deliver us from evil,” originally translated and actually read. “Deliver
    us from the evil one”—far more personally, far more graphic, and far
    more intense—the evil one.
    In the 1960’s, the Rolling Stones came out with a song. The refrain after
    each chorus was, “Pleased to meet you. Hope you guess my name.” And,
    I suggest to you it was a song about the evil one appearing in person
    throughout the ages in many different guises. Mr. Poland says civilized
    society—in a civilized society, we don’t kill. But in civilized society, we
    must address— we must stand up to, we must confront the realities of our
    daily existence and our daily survival not only of ourselves but of our
    children and their children. It came to dawn on me after I thought about,
    “Please to meet you, hope you guess my name”—that on January the 9th,
    1987, the evil one descended upon Patrick and Rosemary Smith, and the
    evil one is smart, the evil one is skilled, the evil one is wily, and the evil
    one is manipulative. A simple little demonstration of that, ladies and
    gentleman, is this. The evil one appeared today and produced greeting
    cards—“Merry Christmas,” “Happy Holidays.” But on January the 8th,
    1987, the evil one appeared at the door of 351Hampshire Drive, a home
    not unlike yours in a neighborhood not unlike yours—the evil one
    appeared there in disguise—a mask, a black jacket, a pistol, strangling
    rope, and the evil one is capable of taking advantage of what was
    available inside their house. Yes, whether you like it or not—whether
    you volunteered or not, you are engaged in the ultimate battle in
    everyday combat with the evil one, and he’s not going to go away. He
    appeared in Minnesota in the form of Jeffrey Dahmer. He appeared in
    Union, South Carolina, and on January the 9th, he appeared at the door
    of Patrick and Rosemary Smith. You cannot negotiate with the evil one,
    ladies and gentlemen. You cannot deal in good faith with the evil one.
    You have got to destroy and destroy, or he and his benefactors will
    destroy you. He’ll destroy us. He’ll destroy our children. The evil one
    took the name of Ronnie Cauthern on that day. That was his name, and
    he’s beyond redemption. He’s beyond redemption. There is no treatment
    for this individual posing in a mask and taking human form. There is no
    treatment for this person. This person has been around through all ages

    and will appear again. You cannot cure him. Don’t try to save him.
    Engage him in combat and destroy him. Do your duty. When you open
    that paper and you find that the State has carried out your instruction, you
    will have scaled the ramparts at least one time, and you will have been
    a part of bringing back peace and tranquility in your community and in
    our community, and you will send a message to the evil one. You will
    send a message that we stand ready—armed, and ready to fight for all in
    the world, for everything that you believe in, for the sanctity of your
    home, the blessing of seeing your children reach adulthood and have
    your grandchildren, and you will take a step and leave a legacy to your
    children that they someday will not have to grapple with what the Smiths
    had to deal with and what Karen Rivetna and her mother have to deal
    with.

    (R. 27, Return Addendum 5, Vol. 4, State Rebuttal at Resentencing, at 463–65, Dec. 7,
    2005.) Petitioner claims that this rebuttal amounted to prosecutorial misconduct, and
    seeks habeas relief on that basis.
    B.      Analysis
    In reviewing a claim for habeas relief based on prosecutorial misconduct in a
    closing argument, “[t]he relevant question is whether the prosecutors’ comments so
    infected the trial with unfairness as to make the resulting conviction a denial of due
    process.” Darden v. Wainwright, 
    477 U.S. 168
    , 181 (1986) (quoting Donnelly v.
    DeChristoforo, 
    416 U.S. 637
    , 643 (1974) (internal quotation marks omitted)).
    “Moreover, the appropriate standard of review for such a claim on writ of habeas corpus
    is ‘the narrow one of due process, and not the broad exercise of supervisory power.’”
    
    Id. (quoting Donnelly,
    416 U.S. at 642) (analyzing a habeas claim prior to the enactment
    of AEDPA). “Past decisions of [the Supreme Court] demonstrate that the touchstone of
    due process analysis in cases of alleged prosecutorial misconduct is the fairness of the
    trial, not the culpability of the prosecutor.” Smith v. Phillips, 
    455 U.S. 209
    , 219 (1982).
    “[T]he cardinal rule [is] that a prosecutor cannot make statements ‘calculated to incite

    the passions and prejudices of the jurors.’” Gall v. Parker, 
    231 F.3d 265
    , 315 (6th Cir.
    2000) (quoting United States v. Solivan, 
    937 F.2d 1146
    , 1151 (6th Cir. 1991)).
    The Tennessee Supreme Court found that the remarks did not unfairly prejudice
    Petitioner. They found that “while . . . the prosecution’s argument was patently
    improper and caution prosecutors against similar argument in the future, we nevertheless
    hold that in this case, the argument did not affect the sentence or render the jury’s
    decision arbitrary or unreliable under the Eighth and Fourteenth Amendments to the
    United States Constitution.” 
    Cauthern, 967 S.W.2d at 738
    . The district court found that
    this decision did not contradict clearly established law, nor was it an unreasonable
    application of law to the facts of this case.
    We, however, find that the Tennessee Supreme Court’s decision was an
    unreasonable application of clearly established federal law.8 The full reasoning of the
    state court was that:
    [T]he argument, while highly improper, did not affect the verdict to the
    prejudice of the defendant. The remarks in question were only a portion
    of the prosecutor’s summation. Although no curative measures were
    taken by the trial court or the prosecution, this was primarily because the
    defense failed to object. We suggest, however, that this is a case in
    which the sua sponte intervention by the trial court would have been
    appropriate. It appears that the prosecution’s motivation in making the
    argument was to respond to defense counsel’s assertion that the
    defendant should not receive a death penalty in a civilized society and
    also to rebut the defendant’s evidence of his rehabilitative potential.
    Finally, the misconduct must be viewed together with the overall record
    8
    Petitioner, in his reply brief, argues that because of the Supreme Court’s decision in Parker v.
    Matthews, 567 U.S. ___, 
    132 S. Ct. 2148
    (2012), AEDPA no longer controls this case, and he is entitled
    to de novo review, because the Tennessee Supreme Court’s decision applied the Sixth Circuit’s multi-step
    analysis for prosecutorial misconduct. The argument is that Parker overturned this Circuit’s multi-step
    analysis, and so the Tennessee Supreme Court’s decision, which tracks that analysis, was in violation of
    clearly established law, because the state court should have applied the Darden approach. But the
    Tennessee Court did analyze this claim pursuant to Darden; the Sixth Circuit approach purportedly
    criticized in Parker was a means of addressing one of the prongs under Darden. In addition, eliminating
    this Circuit’s approach to Darden would not benefit Petitioner, because this Circuit has far more extensive
    case law governing the flagrancy of prosecutorial arguments. Finally, there is no basis for Petitioner’s
    claim that the change in law entitles him to de novo review. The state court was not entitled to violate
    clearly established federal law, but unless its application of the now-defunct (for the purposes of habeas
    review) Sixth Circuit test for flagrancy was itself a violation of clearly established federal law, then this
    Court cannot overturn that decision. In Parker, the criticism of this Court’s reasoning was simply that this
    Court used its own precedents as the basis for clearly established law.

    and the overwhelming strength of the State’s case. The evidence
    supported the aggravating factor relied on by the State, as well as a
    finding that this factor outweighed the evidence of mitigating factors.
    
    Cauthern, 967 S.W.2d at 737
    –38 (internal citations and footnotes omitted). However,
    in light of Supreme Court precedent, this conclusion is entirely unreasonable.
    The prosecutor’s remarks were, as both the district court and the Tennessee
    Supreme Court found, clearly improper. Respondent also agrees that the prosecutor’s
    remarks at sentencing were improper. And there is no reasonable conclusion that one
    can draw from these remarks except that a jury would be inflamed by them. The
    prosecutor’s remarks amounted to a litany of the kinds of remarks that courts disfavor.
    The prosecutor compared Petitioner to two of the most widely despised criminals of the
    then-recent past, one of whom was a serial killer who had tortured and raped his victims
    before murdering and dismembering them, and the other of whom was a child-murderer
    who after drowning her two sons triggered a nationwide manhunt when she fabricated
    a racially charged story that blamed the crime on a nonexistent black man. These
    remarks were solely inflammatory; and while we do not diminish the seriousness of
    Petitioner’s crime, the Smith and Dahmer cases bore no relevant similarity to the crimes
    committed by Petitioner.
    In addition, the prosecutor made biblical references, repeatedly referring to
    Petitioner as “the evil one,” and referring to the Lord’s Prayer. These types of references
    are particularly inappropriate in a sentencing proceeding, because they can create the
    inference that the death penalty is mandatory through their appeal to a higher authority,
    and because they allow a jury to delegate its own responsibility for the imposition of the
    sentence. See, e.g., Romine v. Head, 
    253 F.3d 1349
    , 1366 (11th Cir. 2001); Sandoval
    v. Calderon, 
    241 F.3d 765
    , 777–78 (9th Cir. 2000); Coe v. Bell, 
    161 F.3d 320
    , 351 (6th
    Cir. 1998). The prosecutor made references that would encourage the jury to personally
    identify with the victims, and to feel as though failing to return sentence of death would
    endanger the families of the jury. The prosecutor included an appeal to the duty of the
    jury, which is a form of argument that the Supreme Court has expressly criticized. See
    United States v. Young, 
    470 U.S. 1
    , 18 (1985). While not binding as clearly established
    No. 10-5759        Cauthern v. Colson                                             Page 15
    law, we note that the remarks here bear some resemblance to those in Bates v. Bell,
    
    402 F.3d 635
    , 648 (6th Cir. 2005), cert. denied, 
    126 S. Ct. 163
    (2005) (“The prosecutors
    made it a theme of their summation that the jury’s failure to sentence Bates to
    death would be akin to ordering the execution of Bates’s next victim. Voting for a life
    sentence for this ‘rabid dog’ was equivalent to putting a gun in his hand.”).
    The Tennessee Supreme Court also found that the remarks were only a part of
    the prosecutor’s summation, but as Petitioner points out, up to 80% of the rebuttal was
    dedicated to improper argument, and the rebuttal was the final thing the jury heard
    before it met to decide upon a sentence. Ultimately, the question of whether Petitioner
    is entitled to relief hinges on the likelihood that the remarks prejudiced the defendant
    such that we can no longer be confident in the jury’s sentence of death. 
    Bates, 402 F.3d at 641
    (“Rather than determining whether a constitutional error would have pushed a
    jury from a ‘not guilty’ verdict to a ‘guilty’ verdict, we must attempt to discover whether
    the constitutional error influenced the jury’s decision between life and death.”). Based
    on the number of abuses and the egregiousness of the prosecutor’s conduct, we are
    convinced that no reasonable jurist could be confident in the result as returned by the
    jury.
    While the district court found that the record supported the Tennessee’s Supreme
    Court’s findings that the remarks did not unduly influence the jury, we see no reasoned
    basis for that conclusion anywhere in the opinion. The district court noted that there was
    a great deal of evidence about Petitioner’s guilt, but the weight of the evidence of guilt
    is completely and totally irrelevant to this inquiry. See Gregg v. Georgia, 
    428 U.S. 153
    ,
    190–92 (1976) (discussing the advantages of bifurcated sentencing procedures in capital
    cases). One would hope that when a state court convenes to determine whether a
    defendant should be put to death that there would no longer be any lingering question
    of that defendant’s guilt. The district court also noted that the trial court gave the
    curative instruction that statements by lawyers are not evidence. But that generic
    instruction would likely have been given regardless of what the prosecutor said; were
    we to accept the reasoning of the district court on this point, then there would never be
    No. 10-5759        Cauthern v. Colson                                            Page 16
    a viable claim for prosecutorial misconduct, because the most basic of instructions would
    cure the potential for an inflamed jury. The district court further noted that the
    prosecutor’s remarks were invited by the defense attorney, without explaining why that
    would matter with respect to our confidence in the decision reached. The district court
    also pointed out that the jury was unlikely to have been convinced that Petitioner was
    actually the devil. While that may be true, its real relevance is that it highlights the
    outlandish nature of the prosecutor’s remarks. And one would not need to believe that
    Petitioner was himself the devil in order to have been improperly inflamed such that the
    verdict cannot be trusted.
    Respondent argues (and the district court found) that because the jury returned
    only one sentence of death, for the murder of Rosemary, and returned only a sentence
    of life imprisonment for the murder of Patrick, we can assume that the jury was not
    improperly inflamed, because the prosecutor’s remarks applied with equal force to both
    murders. But this argument is irrational; there were differences between the two
    murders, and it is equally plausible that given the high burden for imposing a death
    sentence, the remarks were what tipped the scale in favor of imposing such a sentence
    for the murder of Rosemary. Petitioner presented mitigating evidence, and there was a
    co-defendant, who was at least equally culpable, who was not sentenced to death. Given
    these facts, and given the extensive and egregious nature of the prosecutor’s remarks,
    we cannot be confident in the result returned by the jury. Based on the quantity of
    prosecutorial misconduct, as well as the severity of that misconduct, no reasonable jurist
    could be confident that Petitioner was accorded a fair proceeding. Accordingly, we
    grant the petition for a writ of habeas corpus on the basis of prosecutorial misconduct.
    IV.     Petitioner’s Eddings Claim
    Petitioner argues that he should have been allowed to introduce a letter from his
    son as mitigation evidence at his resentencing. The letter read in full:
    No. 10-5759         Cauthern v. Colson                                              Page 17
    Dear Dad,
    I Love you Dad. I hope I come again gen [sic]. Some time. we went to
    Chuck [sic] Cheese. We went to Wall [sic] Mart and we had fun.
    Love always, Ryan
    State v. Cauthern, 
    967 S.W.2d 726
    , 738 (Tenn. 1998). The letter was excluded because
    the trial court found that “it was of negligible probative value and was cumulative to the
    other evidence presented.” 
    Id. The Tennessee
    Supreme Court, in its review of that
    decision, found that the failure to admit the evidence was harmless error, 
    id. at 738–39,
    and it is that decision that is reviewed by this Court. The district court found that the
    state court decision not to admit the evidence was neither contrary to, nor an
    unreasonable application of, clearly established federal law, but later granted a certificate
    of appealability on the narrower of question of whether the Tennessee Supreme Court’s
    holding that this was subject to harmless-error analysis violated the Constitution.
    Petitioner alleges that the Tennessee Supreme Court’s decision was an
    unreasonable application of clearly established law because it evaluated this claim
    through the rubric of harmless-error analysis, rather than regarding the error as a
    structural flaw requiring resentencing. At the outset, we note that no party appears to
    contest that the original decision not to admit the evidence was an error. There is no
    question that a defendant subject to the death penalty is permitted to introduce a wide
    range of evidence in mitigation. Failure to permit the sentencer to consider mitigation
    is a violation of the Eighth and Fourtheenth Amendments to the federal Constitution.
    
    Cauthern, 967 S.W.2d at 738
    (citing McKoy v. North Carolina, 
    494 U.S. 433
    , 442
    (1990)). As the Supreme Court found in Eddings v. Oklahoma, 
    455 U.S. 104
    (1982),
    “the sentencer [may not] refuse to consider, as a matter of law, any relevant mitigating
    evidence.” 
    Id. at 114
    (extending the rule from Lockett v. Ohio, 
    438 U.S. 586
    (1978), that
    barred states from precluding mitigation evidence by statute) (emphasis in original).
    “The Constitution requires States to allow consideration of mitigating evidence in
    capital cases. Any barrier to such consideration must therefore fall.” 
    McKoy 494 U.S. at 442
    (1990) (emphasis in original).
    No. 10-5759         Cauthern v. Colson                                             Page 18
    In this case, the state court reasoned that while the trial court had erred in
    refusing to allow the evidence in, there was no basis upon which to overturn the
    conviction, because that error was harmless. It was harmless because the crucial points
    that a sentencing jury could glean from the evidence were permitted as mitigation
    evidence; the jury knew that Petitioner had a son who visited him regularly, and had seen
    a picture of Petitioner with his son. 
    Cauthern, 967 S.W.2d at 739
    . The lower court had
    further instructed the jury that they could consider the fact that Petitioner had a minor
    son as a mitigating factor. 
    Id. Therefore, the
    evidence did not affect the jury’s verdict.
    
    Id. Petitioner now
    challenges the district court’s determination that this was neither an
    unreasonable application of, nor contrary to, clearly established law because, he claims,
    the Tennessee Court of Criminal Appeals should have found that the failure to admit the
    evidence was structural, and thus required resentencing.
    There is no clearly established federal law requiring states to review trial court’s
    decisions regarding admission of mitigating or aggravating factors as structural defects.
    While the Supreme Court has remanded death sentences on the basis of the exclusion of
    relevant mitigation evidence, it has never categorically stated that it is improper for a
    state court to analyze such a claim as a matter of harmless error. The strongest possible
    precedent for Petitioner’s argument is the Supreme Court’s decision in Skipper v. South
    Carolina, 
    476 U.S. 1
    (1986). In that case, the Supreme Court found that:
    The exclusion by the state trial court of relevant mitigating evidence
    impeded the sentencing jury’s ability to carry out its task of considering
    all relevant facets of the character and record of the individual offender.
    The resulting death sentence cannot stand, although the State is of course
    not precluded from again seeking to impose the death sentence, provided
    that it does so through a new sentencing hearing at which petitioner is
    permitted to present any and all relevant mitigating evidence that is
    available.
    
    Id. at 8
    (citation omitted). Furthermore, “[u]nder our decisions, it is not relevant whether
    the barrier to the sentencer’s consideration of all mitigating evidence is interposed by
    statute, by the sentencing court, or by an evidentiary ruling.” Mills v. Maryland,
    
    486 U.S. 367
    , 374 (1988).
    No. 10-5759         Cauthern v. Colson                                             Page 19
    While those cases present a relatively strong argument for Petitioner, it is not
    enough to overcome the AEDPA standard. In those cases, the issue was that the
    mitigation evidence had been excluded entirely; the jury had not been able to consider
    the argument for mitigation at all, or had (as in Mills) misunderstood its directions such
    that it chose not to consider the evidence. Therefore, in those cases, harmless error
    analysis was impossible. See Davis v. Coyle, 
    475 F.3d 774
    –75 (6th Cir. 2007)
    (discussing possible remedies when a court improperly excludes mitigating evidence).
    But in this case, the Court of Criminal Appeals found that the only relevant piece of
    information was cumulative. Here, the Tennessee Courts were able to review the
    determinations and find that the error was harmless, given that the jury heard evidence
    as to the same mitigation factor to which the excluded evidence would have gone.
    In addition, the Supreme Court has repeatedly held that states can review
    mitigation decisions on the basis of harmless error review when the issue is the weighing
    of aggravating and mitigating factors. See Parker v. Dugger, 
    498 U.S. 308
    , 319 (1991);
    Clemons v. Mississippi, 
    494 U.S. 738
    , 752 (1990) (“Even if under Mississippi law, the
    weighing of aggravating and mitigating circumstances were not an appellate, but a jury,
    function, it was open to the Mississippi Supreme Court to find that the error which
    occurred during the sentencing proceeding was harmless.”)
    Finally, it should be noted that the federal statute authorizing review of a federal
    death sentence specifies that “[t]he court of appeals shall not reverse or vacate a sentence
    of death on account of any error which can be harmless, including any erroneous special
    finding of an aggravating factor, where the Government establishes beyond a reasonable
    doubt that the error was harmless.” 18 U.S.C. § 3595(c). It would be strange to find that
    the federal Constitution demands a particular form of review for state court errors
    regarding mitigation evidence when it does not demand the same on direct appellate
    review of federal death sentences.
    Accordingly, the state court decision with respect to the entry of this mitigation
    evidence did not violate clearly established law when it applied harmless error analysis
    to the lower court’s evidentiary ruling.
    No. 10-5759            Cauthern v. Colson                                                       Page 20
    V.       Petitioner’s Brady Claim
    Petitioner claims that the state courts erred in failing to reverse his conviction on
    the basis that the state withheld material exculpatory evidence in violation of Brady v.
    Maryland, 
    373 U.S. 83
    (1967). Specifically, Petitioner claims that there were three
    pieces of information that should have been turned over to him: a police report from
    January 23, 1987 prepared by Detective R.J. DiFiore, which addressed an interview with
    James Andrew, a witness for the prosecution; the fact that Andrew had received money
    from the police in exchange for his statement to the police; and finally, the fact that
    Andrew’s car had been vandalized after Petitioner was arrested.9
    The police report memorialized the original statement given to the police by
    Andrew. According to the report, Eric Barbee, a friend of Patterson’s, had come to
    Andrew’s home, and told Andrew to contact Patterson’s attorney to report that Patterson
    had stayed in the car while Petitioner committed the rape and murders, and to further
    report that he had not seen Petitioner with Patterson on the night of the murders.
    Petitioner alleges that the prosecution also suppressed evidence that Andrew had
    contacted the police expecting to receive a $5,000.00 reward, and did in fact receive
    some amount of money. Finally, Petitioner alleges that the prosecution suppressed
    evidence that Andrew’s car had been vandalized, sometime after Petitioner was arrested
    and after Barbee had contacted Andrew. The Tennessee Court of Criminal Appeals
    found that while the evidence was favorable to Petitioner, and had been suppressed,
    Cauthern v. State, 
    145 S.W.3d 571
    , 621 (Tenn. Crim. App. 2004), this evidence was not
    material; because Petitioner had not shown that had it been disclosed to him, there was
    a reasonable probability that the result of either the trial or the resentencing would have
    9
    Andrew’s testimony at the original trial mentioned various admissions by Petitioner regarding
    the rape and murder. In addition, as the district court stated:
    Andrew was the State’s final witness at the 1995 resentencing hearing. Although
    Andrew’s testimony in 1988 about the murders . . . had faded by the time of the 1995
    resentencing hearing, he repeated his earlier testimony that the petitioner admitted
    having raped Rosemary, adding that the petitioner viewed raping her as a “great trophy,”
    and that he was “proud of it.”
    (R. 167, Mar. 31, 2010, Opinion, at 27.)
    No. 10-5759            Cauthern v. Colson                                                          Page 21
    been different. 
    Id. The district
    court found that the state court’s determination did not
    give rise to habeas relief, and declined to grant the writ on the basis of the alleged Brady
    violations.
    Under Brady, a defendant’s rights under the Due Process Clause are violated
    when a state suppresses material exculpatory information. Brady v. Maryland, 
    373 U.S. 83
    , 87 (1963). The Supreme Court has stated that the elements of a Brady claim are:
    “The evidence at issue must be favorable to the accused, either because it is exculpatory,
    or because it is impeaching; that evidence must have been suppressed by the State, either
    willfully or inadvertently; and prejudice must have ensued.” Strickler v. Greene,
    
    527 U.S. 263
    , 381–82 (1999). In this case, the state court found that the evidence was
    favorable and had been suppressed, but was not material.10 
    Cauthern, 145 S.W.3d at 619
    . Accordingly, the court declined to reverse either Petitioner’s conviction or sentence
    on the basis of Brady violations.
    To determine if evidence is material, courts must use the standard of reasonable
    probability; if there is a reasonable probability that, had the evidence been turned over,
    the underlying proceeding would have had a different result, then the evidence is
    material. Youngblood v. West Virginia, 
    547 U.S. 867
    , 870 (2006). “The question is not
    whether the defendant would more likely than not have received a different verdict with
    the evidence, but whether in its absence he received a fair trial, understood as a trial
    resulting in a verdict worthy of confidence.” 
    Strickler, 527 U.S. at 289
    –90 (quoting
    Kyles v. Whitley, 
    514 U.S. 419
    , 434 (1995)) (internal quotation marks and citations
    omitted). Additionally, a court examining the materiality of evidence under Brady
    examines the evidence in its totality, rather than as a series of individual items. 
    Kyles, 514 U.S. at 436
    –37.
    10
    The Tennessee Court of Appeals specifically held that “the state does not earnestly contest the
    two findings [that the state suppressed the evidence], although it does argue that some of the information
    seemed to be available to both parties.” 
    Cauthern, 145 S.W.3d at 620
    . The court did not challenge the
    lower court’s finding with respect to suppression of the evidence, nor did it find that evidence of vandalism
    was ineligible for Brady treatment on that ground.
    No. 10-5759           Cauthern v. Colson                                                      Page 22
    Petitioner alleges that this evidence was material because it could have been used
    to impeach Andrew’s testimony at both the original trial and the resentencing hearing.11
    During state collateral proceedings, the Tennessee Court of Criminal Appeals found that
    the evidence was immaterial, because even if Andrew’s credibility had been completely
    undermined, the verdict would have remained intact. This was in part because Petitioner
    was convicted under the felony-murder rule, and accordingly, there was no need for the
    state to prove that Petitioner had himself killed the Smiths. Therefore, even without
    Andrew’s testimony as to Petitioner’s admissions, there was sufficient proof of
    Petitioner’s guilt to support the verdict. 
    Cauthern, 145 S.W.3d at 620
    . It further
    reasoned that the testimony as to Barbee’s attempt to influence Andrew was irrelevant
    because Andrew gave a statement to police before Barbee contacted him, and in any
    event, Andrew’s testimony did not negate Patterson’s involvement in the crimes, which
    was the reason Barbee contacted him. Finally, even without evidence of Andrew’s
    monetary reward, the resentencing jury declined to impose a death penalty for one
    killing, and the distinguishing factor of the other killing was that the victim was tortured,
    a topic to which Andrew’s testimony had no relevance. 
    Id. at 621.
    Petitioner presents no substantive argument that the state court’s decision
    violated clearly established law. His most compelling argument is that because his claim
    at sentencing related to relative culpability between him and Patterson, the evidence that
    Patterson attempted to tamper with the witness was material to the jury’s determination
    of greater relative culpability. But even had that evidence come in, the state court’s
    judgment would still have been supported by another witness’ account that Petitioner
    had raped Rosemary. And Petitioner cites no cases in support of his argument, nor can
    the author find any supporting Supreme Court precedent for the contention that relative
    culpability gives rise to a definite inference of materiality under Brady.
    Furthermore, although Andrew’s discussion of Petitioner’s boasts about killing
    Rosemary might have influenced the jury to impose a sentence of death, it was not the
    11
    Andrew did not testify at the post-conviction evidentiary hearing, but the parties agreed to
    stipulate to what he would have said.
    No. 10-5759         Cauthern v. Colson                                            Page 23
    only evidence supporting that sentence. Petitioner does not show any clearly established
    law that would suggest that his inability to impeach Andrew would have affected the
    jury’s decision given the overwhelming physical evidence that Rosemary was tortured.
    Because Andrew’s testimony at the resentencing was relatively brief, and there was
    overwhelming evidence as to the key points of his testimony, the Tennessee court’s
    finding that his impeachment would not have undermined confidence in the outcome is
    not reversible under AEPDA’s deferential standard of review.
    Accordingly, the decision of the district court to deny Petitioner’s claim for
    habeas relief under Brady is affirmed.
    VI.     Ineffective Assistance of Counsel
    A.      Standard of Review
    The standard of review for this claim, as well as the governing law under
    AEDPA is the same as provided in the earlier section of this decision; however, it should
    be noted that the Supreme Court has made clear that claims under Strickland are
    extremely difficult under AEDPA:
    Surmounting Strickland’s high bar is never an easy task. . . . Even under
    de novo review, the standard for judging counsel’s representation is a
    most deferential one. . . .
    Establishing that a state court’s application of Strickland was
    unreasonable under § 2254(d) is all the more difficult. The standards
    created by Strickland and § 2254(d) are both highly deferential, and
    when the two apply in tandem, review is doubly so . . . . [T]he question
    is not whether counsel’s actions were reasonable. The question is
    whether there is any reasonable argument that counsel satisfied
    Strickland’s deferential standard.

    No. 10-5759         Cauthern v. Colson                                           Page 24
    B.      Petitioner’s claim of ineffective assistance of counsel
    Petitioner’s next claim is that his counsel was ineffective because it failed to
    adequately investigate or present his claims for mitigation.         The district court
    summarized these claims as failure to:
    1) present testimony from his step-siblings; 2) present testimony from
    family friends and the petitioner’s ex-wife; 3) retain investigative and
    expert assistance and present expert testimony; 4) investigate Patterson’s
    background 5) cross-examine Andrew adequately; 6) challenge
    Denning’s testimony about the wine coolers when no physical evidence
    or expert testimony had been presented to support his testimony;
    7) comply with the ABA standards for defense counsel in a capital case;
    8) explain or present the petitioner’s life history, character and
    background, or explain the crime, i.e., present mitigating evidence
    persuasively, or object to the trial court’s ruling that the jury could not
    consider Patterson’s life sentence as mitigating evidence; and 9) present
    available mitigating evidence, thereby undermining the confidence in the
    integrity of the petitioner’s death sentence.
    (R. 167, Mar. 31, 2010, Opinion, at 69.)
    The question of ineffective assistance of counsel is analyzed pursuant to the two-
    part test established in Strickland v. Washington, 
    466 U.S. 668
    (1984). Petitioner must
    show that counsel’s performance was objectively unreasonable, and that he was
    prejudiced because of this ineffective assistance.
    Counsel’s performance is deficient where it falls below an objectively reasonable
    standard. 
    Strickland, 466 U.S. at 686
    –87; 
    Richter, 131 S. Ct. at 787
    . “A court
    considering a claim of ineffective assistance must apply a ‘strong presumption’ that
    counsel’s representation was within the ‘wide range’ of reasonable professional
    assistance.” 
    Richter, 131 S. Ct. at 787
    (quoting 
    Strickland, 466 U.S. at 689
    ). Petitioner
    bears the burden of overcoming the “presumption that the challenged conduct might be
    considered sound trial strategy.” 
    Hanna, 694 F.3d at 612
    . That is to say, Petitioner must
    show that counsel made errors “so serious that counsel was not functioning as the
    counsel guaranteed the defendant by the Sixth Amendment.” 
    Richter, 131 S. Ct. at 787
    (internal quotation marks omitted).
    No. 10-5759            Cauthern v. Colson                                                      Page 25
    “To establish Strickland prejudice a defendant must ‘show that there is a
    reasonable probability that, but for counsel’s unprofessional errors, the result of the
    proceeding would have been different.’” 
    Lafler, 132 S. Ct. at 1384
    (quoting 
    Strickland, 466 U.S. at 694
    ). “‘A reasonable probability is a probability sufficient to undermine
    confidence in the outcome.’” 
    Richter, 131 S. Ct. at 787
    (quoting 
    Strickland, 466 U.S. at 694
    ). “Counsel’s errors must be so serious as to deprive the defendant of a fair trial, a
    trial whose result is reliable.”

    1.       Petitioner’s Claim of Ineffective Assistance Due to Counsel’s
    Failure to Present Testimony of His Step-Siblings
    Petitioner’s first claim for ineffective assistance of counsel was that his attorney
    failed to present testimony at his sentencing hearing from Petitioner’s step-siblings as
    to his abusive childhood. Three of his step-siblings, Melinda Cauthern Allen, Roy
    “Bud” Cauthern, Jr., and Eveann Cauthern Palmer, later testified at a post-conviction
    evidentiary hearing.12 Their testimony detailed a litany of abuse, mostly inflicted by
    12
    The Tennessee Court of Appeals described Petitioner’s family background at some length:
    The petitioner was born in Tennessee on September 5, 1967. His biological parents were
    Raymond Huhn, a German citizen, and Christine Tatteryn Huhn, a Canadian citizen.
    During Christine Huhn’s pregnancy, Raymond Huhn was arrested for burglary and
    imprisoned in California. Needing a place to live, Christine Huhn contacted her
    mother-in-law, Dagmar Huhn Cauthern, who lived in Tennessee and who invited
    Christine Huhn to stay with the Cauthern family.
    Dagmar Huhn’s husband, Roy Cauthern, Sr., had served in the military during World
    War II. Evidently, while he was stationed in Germany, he met his future wife, a German
    citizen who ultimately became a casualty of the Allied bombings of that country. Little
    is known of Dagmar Huhn’s life in Germany other than giving birth to one child,
    Raymond. Many years after the surrender of Germany and Japan, Dagmar Huhn
    immigrated to the United States and renewed her acquaintance with Roy Cauthern, Sr.
    He had been recently widowed in 1962, and he was a single parent to four children:
    Melinda, Mary Louise, Eveann, and Roy Cauthern, Jr. In February of 1963, Dagmar
    Huhn and Roy Cauthern, Sr. were married.
    Christine Huhn gave birth in 1967 to the petitioner while she was living with the
    Cautherns. When the petitioner was approximately six weeks old, Dagmar Cauthern
    prevailed upon Christine Huhn to return to California to divorce Raymond Huhn. When
    Christine Huhn left, Dagmar Cauthern then reported that Christine had abandoned her
    child, which allowed Dagmar and Roy Cauthern to officially adopt the petitioner. The
    petitioner first learned of his adopted status when he was a teenager and discovered his
    birth certificate.
    By the time of the post-conviction hearings in 2000 and 2001, the petitioner’s biological
    parents were deceased. His adoptive father, Roy Cauthern, died in 1997, and his
    adoptive mother/biological grandmother, Dagmar Cauthern, was suffering from
    Parkinson’s Disease and living in a nursing home. His stepsister, Mary Louise,
    No. 10-5759           Cauthern v. Colson                                            Page 26
    Dagmar Cauthern, Petitioner’s grandmother. That abuse included physical abuse with
    brooms, belts and other implements. The abuse was largely unpredictable. There was
    also emotional abuse, including the isolation of the children from friends, and verbal
    insults. In addition, home discipline was rigidly enforced with the threat of physical
    violence and deprivation of food.
    The Tennessee Court of Criminal Appeals found that this did not give rise to a
    claim for ineffective assistance of counsel, because Petitioner failed to show that his trial
    counsel’s representation was deficient, and because there was no prejudice. The
    deficiency argument was based largely upon the fact that:
    [T]he post-conviction court found that background family information
    was not readily available to trial counsel. From the testimony and
    demeanor of the petitioner’s step-siblings, former wife, and the Popes,
    the court was convinced that Roy Cauthern “would have done everything
    in his power to prevent witnesses from offering any testimony which did
    not cast Dagmar in a favorable light” and that he would not have
    “permitted his children to discuss family issues with trial counsel, an
    expert witness, or a jury.” As for the Popes and Bud and Melinda
    Cauthern, the court did not believe that they would have assisted with the
    petitioner’s defense unless Roy Cauthern had consented. According to
    the court, the only lay witnesses “who even arguably would have
    cooperated [were] EveAnn and Lucinda.”
    Cauthern v. 
    State, 145 S.W.3d at 606
    (alterations in original).
    Before this Court, Petitioner contends—and the state does not meaningfully
    contest—that the failure of counsel to investigate his family constituted deficient
    performance. An unexplained failure to investigate possible mitigation evidence is
    objectively unreasonable conduct by an attorney in a capital case. See Wiggins v. Smith,
    
    539 U.S. 510
    , 521–22 (2003). As the Supreme Court found in Strickland:
    [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
    succumbed to leukemia in 1980, but the other step-siblings were alive.
    Cauthern v. 
    State, 145 S.W.3d at 583
    .
    No. 10-5759         Cauthern v. Colson                                             Page 27
    precisely to the extent that reasonable professional judgments support the
    limitations on investigation. In other words, counsel has a duty to make
    reasonable investigations or to make a reasonable decision that makes
    particular investigations unnecessary. In any ineffectiveness case, a
    particular decision not to investigate must be directly assessed for
    reasonableness in all the circumstances, applying a heavy measure of
    deference to counsel’s judgments.
    
    Strickland, 466 U.S. at 521
    –22 (quoted with approval in Wiggins); see also Porter v.
    McCollum, 
    558 U.S. 30
    , 39–40 (2009). But here, there is no evidence anywhere in the
    record that explains counsel’s failure to speak to Petitioner’s step-siblings. The district
    court summarized defense counsel’s explanations as:
    Attorney Poland, lead defense counsel at both the 1988 trial and 1995
    resentencing hearing, testified at the post-conviction evidentiary hearing
    that he did not contact the petitioner’s step-siblings, but that the
    petitioner also did not bring anything to his attention that would have
    caused him to suspect that the petitioner’s home life might be of value to
    the defense. Attorney Poland also testified that he did seek family
    background information from the petitioner’s adoptive parents but
    “wasn’t too successful . . . “Attorney Bateman, co-counsel at the 1995
    resentencing hearing, testified that he “had some background from
    discussions with Mr. Poland and Mr. Cauthern . . . ,” but admitted that he
    did not meet or speak with the petitioner’s step-siblings.
    (R. 167, Mar. 31, 2010, Opinion, at 73.) Even if one assumes that the testimony of two
    of the step-siblings suggests that the state court did not err when it found that they might
    not even have testified unless it was acceptable to their father (who had died by the time
    the post-conviction hearing took place), that would only go to possible prejudice; the
    failure to contact the siblings at all was simply deficient performance. Were it true that
    the siblings would not have testified, then a court could plausibly find that there was no
    prejudice because of counsel’s failure to investigate the possibility of their testimony.
    But to fail to investigate a defendant’s nearest relatives at all is deficient performance,
    regardless of what the end result might have been.
    Based on the testimony of the step-siblings, there was no factual basis for the
    state court’s finding that they would not have testified. While Melinda, when asked if
    she would have assisted Petitioner in 1987, said “I doubt it,” she immediately afterwards
    No. 10-5759        Cauthern v. Colson                                             Page 28
    added that she would have helped if properly approached in 1988 or 1995. (Joint App’x
    at 1227–1228.) Roy admitted that he might not have done it if it would have been
    hurtful to their father, but also added that he assumed his father would have wanted him
    to testify. (Id. at 1336–37.) And Eveann was unequivocal in stating that she would
    have testified on Petitioner’s behalf. (Id. at 1370–71.) Therefore, even if this Court
    defers entirely to the state court’s findings with respect to Roy and Melinda, there would
    still be a finding of deficient performance, because at least one of these step-siblings
    would have testified, and only one was necessary to elicit the relevant information.
    Moreover, even were the failure to investigate based on some sort of strategic
    decision—and unlike a decision not to have a potential witness testify after an
    investigation, it is hard to imagine what that strategy would be—“[t]he relevant question
    is not whether counsel’s choices were strategic, but whether they were reasonable.” Roe
    v. Flores-Ortega, 
    528 U.S. 470
    , 481 (2000). In addition, as the Supreme Court recently
    found, “[w]e certainly have never held that counsel’s effort to present some mitigation
    evidence should foreclose an inquiry into whether a facially deficient mitigation
    investigation might have prejudiced the defendant.” Sears v. Upton, ___ U.S. ___, 
    130 S. Ct. 3259
    , 3266 (2010).
    Though the issue was effectively foreclosed by the state’s finding of no deficient
    performance, and there was no need to address the second prong of Strickland, the state
    court went on to find a lack of prejudice, arguing that:
    Even though the petitioner’s step-siblings undoubtedly endured abusive,
    isolated childhoods, it is by no means obvious from the proof that the
    petitioner’s childhood rivaled theirs. The evidence does not preponderate
    against the post-conviction court’s assessment that the petitioner led “a
    charmed life in comparison to his siblings, that he wasted his opportunity
    to become a productive citizen despite [his adopted father’s] attempts to
    foster his car-repair skills, and that he abandoned his wife and child.” To
    be sure, evidence about life in the Cauthern household would have been
    admissible during the penalty retrial; however, the test for prejudice in
    the post-conviction, ineffective assistance context is more exacting. [T]he
    quality of the proposed testimony rather than the quantity of witnesses
    determines whether prejudice has been established.
    No. 10-5759         Cauthern v. Colson                                              Page 29
    In our opinion, the family-history evidence is, at best, marginal in terms
    of illuminating the case in such a way as to undermine confidence in the
    jury’s sentencing decision. At worst, the evidence is reminiscent of the
    adage in Strouth v. State, 
    755 S.W.2d 819
    , 827 (Tenn. Crim. App.1986),
    that “while many people have unhappy childhoods, [few commit brutal
    murders].” Inasmuch as the petitioner’s step-siblings do not manifest
    obvious antisocial traits or violent tendencies, a jury reasonably could
    reject, or be insulted by, any suggestion that the petitioner’s criminal
    actions were attributable to a disadvantaged background.
    Cauthern v. 
    State, 145 S.W.3d at 609
    (some citations and quotation marks omitted).
    But this is an unreasonable interpretation of federal law. First, as noted above,
    a criminal defendant, particularly in a death penalty case, is given wide latitude in the
    introduction of mitigation evidence. See Eddings v. Oklahoma, 
    455 U.S. 104
    (1982).
    Next, it is clearly established law that evidence of abuse is significant to a jury’s
    determination of moral culpability. The Supreme Court has held that “the graphic
    description of [Petitioner’s] childhood, filled with abuse and privation, or the reality that
    he was ‘borderline mentally retarded,’ might well have influenced the jury’s appraisal
    of his moral culpability.” Williams v. Taylor, 
    529 U.S. 362
    , 398 (2000); see Penry v.
    Lynaugh, 
    492 U.S. 302
    , 315 (requiring jury to be able “to fully consider and give effect
    to the mitigating evidence of [Petitioner’s] mental retardation and abused background.”)
    (abrogated on other grounds by Atkins v. Virginia, 
    536 U.S. 304
    (2002)). The Tennessee
    Court of Criminal Appeals found that the failure to present this evidence was not
    prejudicial, because “a jury reasonably could reject, or be insulted by, any suggestion
    that the petitioner’s criminal actions were attributable to a disadvantaged background.”
    Cauthern v. State, 
    145 S.W.3d 571
    , 609 (Tenn. Crim. App. 2004). But that kind of
    speculation is precisely why the failure to introduce this evidence was prejudicial. While
    some degree of speculation is necessary in determining prejudice, Goodwin v. Johnson,
    
    632 F.3d 301
    , 328 (6th Cir. 2011) (citing 
    Sears, 130 S. Ct. at 3265
    –66 (2010)), the state
    court’s speculation was inapposite. The fact that the jury might have taken this evidence
    as proof that Petitioner’s childhood did not mitigate his culpability does not eliminate
    the possibility that there was a reasonable probability that the jury would have found that
    it did mitigate his culpability. Without citing a single federal case, the Tennessee court
    No. 10-5759            Cauthern v. Colson                                                          Page 30
    found that this evidence would not have led a reasonable jury to find a lesser degree of
    moral culpability. But the only other evidence of the potential impact of abuse on
    Petitioner consisted of his own testimony, which is on its face less compelling than the
    testimony of a less interested party. Testimony from his siblings could very well have
    elicited sympathy, or given the jury greater reason to consider life imprisonment. See
    e.g., Johnson v. Mitchell, 
    585 F.3d 923
    , 941–43 (6th Cir. 2009) (finding that defense
    counsel’s failure to investigate leads that might have led to evidence of abuse was
    ineffective, and that the state court’s determination of the opposite conclusion violated
    clearly established law). The Tennessee court’s decision was therefore an unreasonable
    application of the law, given the facts in this case, and accordingly, the decision of the
    district court is reversed.
    2.        Petitioner’s Claim of Ineffective Assistance Due to Counsel’s
    Failure Investigate Patterson’s Involvement in a Similar
    Crime in New Mexico
    Petitioner’s next claim for ineffective assistance of counsel is that trial counsel
    failed to adequately investigate Patterson’s background. Patterson was suspected of a
    rape and murder in New Mexico. Petitioner argues that had this information been
    available, and presented to the jury, it would have supported his theory that Patterson
    had greater moral culpability.13 The Tennessee Court of Criminal Appeals found that:
    The petitioner charges that had trial counsel investigated Patterson’s
    background, counsel would have discovered that Patterson was a suspect
    in the strangulation death of a woman in New Mexico. The petitioner,
    however, fails to explain why trial counsel should have set out on such
    a course of investigation prior to his 1988 trial or even how such
    information relating to an unsolved homicide would have been
    uncovered. The petitioner has offered no evidence of deficient
    performance on this point in connection with his 1988 trial.
    Furthermore, as the post-conviction court noted, assuming the evidence
    could be categorized as relevant for some non-propensity purpose, the
    petitioner has not shown by clear and convincing evidence that Patterson
    13
    Petitioner originally brought this argument with respect to both his trial and sentencing, but now
    pursues the argument only as it relates to the 1995 resentencing.
    No. 10-5759        Cauthern v. Colson                                             Page 31
    actually committed the offense. The failure to establish a proper
    foundation would have resulted in the exclusion of the evidence.
    The petitioner then shifts to his 1995 resentencing trial. By that time, the
    petitioner claims, Patterson’s suspected involvement in the New Mexico
    homicide was known through other proceedings. The petitioner criticizes
    counsel for not independently investigating “this startling information”
    once it came to light, but there appears to be little to investigate. The
    testimony of the New Mexico law enforcement officers at the
    post-conviction hearing was not particularly revealing or useful beyond
    the initial proposition that Patterson was a suspect.
    Cauthern v. 
    State, 145 S.W.3d at 616
    .
    On this claim, however, Petitioner cannot show deficient performance. First, it
    is unclear that a reasonable investigation would have turned up this evidence before trial.
    Even assuming that Petitioner could show deficient performance, it was not
    unreasonable for the state court to find that there was no prejudice as to this evidence.
    The evidence tying Patterson to the New Mexico killing was inadmissible in the
    proceedings before the trial court. 
    Id. at 597.
    The case against Patterson in New Mexico
    remains technically unsolved, and as the district court found, a reasonable juror would
    not have concluded that the evidence from the 1981 killing in New Mexico had any
    bearing on Petitioner’s relative culpability, especially as an existing witness had already
    put Patterson’s admissions regarding his lead role in the killings before the jury. 
    Id. This evidence
    might have reasonably found Patterson to be more culpable and thus
    resulted in his being sentenced to death, but the evidence is of no importance with
    respect to Petitioner’s culpability, given the otherwise overwhelming evidence of
    Petitioner’s guilt. Accordingly, because even if the investigation was deficient, there was
    no prejudice based on its failure, Petitioner’s claim with respect to the evidence of
    Patterson’s involvement in the New Mexico killing is denied.
    VII.    The Court’s Use of the “Heinous, Atrocious, or Cruel” Aggravating
    Factor
    Petitioner’s final claim is that Tennessee’s use of the “heinous, atrocious, or
    cruel” (“HAC”) aggravating factor is unconstitutionally vague. Particularly, he claims
    No. 10-5759         Cauthern v. Colson                                             Page 32
    that the state court erred when it found that the trial court’s error in using the incorrect
    version of the aggravating statute was harmless. The clearly established standard for
    evaluating whether a constitutional error was harmless is that the state must show
    “beyond a reasonable doubt that the error complained of did not contribute to the verdict
    obtained.” Chapman v. California, 
    386 U.S. 18
    , 24 (1967).
    Tennessee amended its HAC statute in 1989. Prior to 1989, the statute stated
    “[t]he murder was especially heinous, atrocious, or cruel in that it involved torture or
    depravity of mind.” Tenn. Code Ann. § 39-2-203(i)(5)(1982). In 1989, the statute was
    amended to state that “[t]he murder was especially heinous, atrocious, or cruel in that
    it involved torture or serious physical abuse beyond that necessary to produce death.”
    Tenn. Code Ann. § 39-13-204(i)(5) (1991). At the 1995 resentencing the court used the
    post-1989 language. As the Tennessee Supreme Court found, this was error; the court
    should have used the version of the statute that was in effect at the time of the offense.
    State v. Cauthern, 
    967 S.W.2d 726
    , 732 (1998). But it found that the difference between
    the two statutes was harmless, in light of the court’s instructions to the jury.
    This decision was not contrary to or an unreasonable application of federal law.
    First, the Supreme Court has found that HAC aggravators are constitutionally
    permissible if construed so as to require “torture or serious physical abuse.” Maynard
    v. Cartwright, 
    486 U.S. 356
    , 364–65 (1988). And as the district court found, the HAC
    language used by the state court, if accompanied by a limiting instruction, has been
    expressly approved of by the Supreme Court. Bell v. Cone, 
    543 U.S. 447
    , 455 (2005).
    In Cone, the Supreme Court stated that even if it assumed that the Sixth Circuit was
    correct when it found that Tennessee’s HAC aggravator was unconstitutionally vague
    on its face, it could not presume that the state court had failed to cure this vagueness.
    
    Id. at 459–60.
    At resentencing, the trial court gave explanations as to the terms used in the
    aggravating factor. It defined heinous, atrocious, or cruel according to the correct
    standard. State v. 
    Cauthern, 967 S.W.2d at 732
    . It further defined torture correctly. 
    Id. The only
    error in the court’s instructions was the substitution of “serious physical abuse
    No. 10-5759          Cauthern v. Colson                                          Page 33
    beyond that necessary to produce death” in place of the older “depravity of mind”
    language. But that error was inconsequential because there was ample evidence of
    torture. As the court found:
    The victim, Rosemary Smith, was placed in a closet, first enduring the
    mental anguish of her husband’s murder in the next room. She then was
    raped twice, ridiculed, suffered through a bungled attempt at
    strangulation and strangled to death with a tourniquet device placed
    around her neck that caused massive damage to her throat and larynx.
    There was evidence that the victim struggled to save herself while still
    alive and conscious by attempting to release the pressure which was
    applied to her neck. After the blood supply was finally cut off at the end
    of the struggle, she may have lost consciousness in thirty seconds but
    remained alive for three to six minutes.
    
    Id. Accordingly, it
    was not a violation of clearly established law for the Tennessee
    Supreme Court to find this error harmless. What law does exist with respect to
    Tennessee’s HAC aggravator clearly supports the conclusion that the statute, with the
    limiting instructions given, is constitutional, and the difference in language between the
    two versions of the statute was irrelevant to the determination. Therefore the decision
    of the district court with respect to this claim is affirmed.
    CONCLUSION
    For the foregoing reasons, we AFFIRM the decision of the district court with
    respect to Petitioner’s claims under Eddings and Brady, as well as with respect to state’s
    use of the heinous, atrocious, or cruel aggravator at sentencing. However, we GRANT
    the petition for a conditional writ of habeas corpus based on Petitioner’s claims of
    ineffective assistance of counsel and prosecutorial misconduct, and order the state to
    commence resentencing proceedings for Petitioner within 180 days or vacate his
    sentence of death.

    DISSENT
    _______________
    ROGERS, Circuit Judge, dissenting. I join all but parts III. B. and VI. B. 1. of
    the majority’s opinion.
    First, the Tennessee Supreme Court was not unreasonable in finding insufficient
    prejudice from the prosecutor’s clearly improper remarks. Equating the defendant with
    the devil incarnate, Susan Smith, and Jeffery Dahmer was clearly improper. But the
    Tennessee Supreme Court could reasonably find that this extreme and belabored
    metaphor did not cause the jury to impose the death sentence, in the face of the
    extraordinarily brutal facts of this case. The Tennessee Supreme Court found that:
    The victim, Rosemary Smith, was placed in a closet, first enduring the
    mental anguish of her husband’s murder in the next room. She then was
    raped twice, ridiculed, suffered through a bungled attempt at
    strangulation and strangled to death with a tourniquet device placed
    around her neck that caused massive damage to her throat and larynx.
    There was evidence that the victim struggled to save herself while still
    alive and conscious by attempting to release the pressure which was
    applied to her neck. After the blood supply was finally cut off at the end
    of the struggle, she may have lost consciousness in thirty seconds but
    remained alive for three to six minutes.
    State v. Cauthern, 
    967 S.W.2d 726
    , 732 (Tenn. 1998). Although the Tennessee Supreme
    Court’s reasoning was brief with regard to the prejudice caused by the prosecutor’s
    remarks, its central reasoning was clear: “the misconduct must be viewed together with
    the overall record and the overwhelming strength of the State’s case. The evidence
    supported the aggravating factor relied on by the State, as well as a finding that this
    factor outweighed the evidence of mitigating factors.” 
    Id. at 737–38.
    This analysis is a reasonable application of Supreme Court law. It mirrors the
    reasoning used by the Court in Darden v. Wainwright, 
    477 U.S. 168
    (1986). As the
    Supreme Court there explained, “it is not enough that the prosecutors’ remarks were
    undesirable or even universally condemned. The relevant question is whether the
    No. 10-5759        Cauthern v. Colson                                             Page 35
    prosecutors’ comments so infected the trial with unfairness as to make the resulting
    conviction a denial of due process.” 
    Id. at 181
    (internal quotation marks omitted). In
    this case, as in Darden, “[t]he weight of the evidence against the petitioner was heavy;
    the overwhelming eyewitness and circumstantial evidence to support a finding of guilt
    on all charges reduce the likelihood that the jury’s decision was influenced by the
    closing argument.”     
    Id. at 182
    (internal quotation marks and citation omitted).
    Considering the substantial evidence of the grisly manner in which Rosemary was killed,
    it was reasonable to conclude that the prosecutor’s remarks did not rise to the level of
    a due process violation because the jury would not have needed to rely on the
    prosecutor’s remarks to find the aggravating factor.
    The Tennessee Supreme Court also noted that the prosecutor’s closing argument
    appeared to be a response to defense counsel’s suggestion that a civilized society should
    not impose the death penalty and a rebuttal of Cauthern’s evidence of his rehabilitative
    potential. 
    Cauthern, 967 S.W.2d at 737
    –38. The concept of invited response was relied
    upon by the Supreme Court in Darden. There the Court explained that “the idea of
    ‘invited response’ is used not to excuse improper comments, but to determine the effect
    on the trial as a whole.” 
    Darden, 477 U.S. at 182
    . Whether the response is invited is
    relevant to the analysis because a prosecutor’s improper remarks are less likely to affect
    the fairness of the trial if their purpose was merely to “right the scale” in response to a
    defendant’s arguments. United States v. Young, 
    470 U.S. 1
    , 12–13 (1985). Although the
    prosecutor’s remarks went well beyond what was necessary to respond to the defense,
    it was still reasonable for the state court to conclude that the prosecutor’s remarks were
    less likely to cause prejudice in the context of the defense’s commentary on the propriety
    of the death penalty in a civilized society.
    The reasonableness of the state court’s decision is buttressed by the fact that just
    last year the Supreme Court reminded us that “the Darden standard is a very general one,
    leaving courts ‘more leeway . . . in reaching outcomes in case-by-case determinations.’”
    Parker v. Matthews, 
    132 S. Ct. 2148
    , 2155 (2012) (quoting Yarborough v. Alvarado,
    
    541 U.S. 652
    , 664 (2004)). The less specific a rule is, the more room there is for
    No. 10-5759        Cauthern v. Colson                                             Page 36
    disagreement over how the rule ought to apply, and the more likely a given application
    is to be reasonable. 
    Yarborough, 541 U.S. at 664
    . The generality of the Darden
    standard makes it all the more difficult to find that the Tennessee Supreme Court’s
    application of federal law was unreasonable.
    Moreover, even if the Tennessee high court’s analysis was so cryptic and
    unpersuasive as to be unreasonable, that would not necessarily mean that Cauthern
    succeeds on this appeal, but rather that we would decide de novo whether there was a
    constitutional violation. See Rice v. White, 
    660 F.3d 242
    , 257 (6th Cir. 2011). Under
    an independent application of the relevant standard from Brecht v. Abrahamson, 
    507 U.S. 619
    , 623 (1993), the error was harmless. First, the factors discussed above—the
    significant evidence of torture and the fact that defense counsel invited the prosecutor’s
    response—weigh in favor of a finding of no injurious effect on the verdict. Next, almost
    immediately after the prosecutor’s remarks, the judge instructed the jury that
    “[s]tatements, arguments and remarks of the lawyers . . . [are] not evidence” and later
    that the jury should make its decision based on the facts and not “sympathy or
    prejudice.” Even if generic, such an instruction is still relevant in a harmless error
    review. The fact that the instructions were given is a factor that should be considered
    when evaluating the effect of an error on the verdict. The significant evidence before
    the jury along with the “important presumption that jurors followed the trial court’s
    instructions,” United States v. Guzman, 
    450 F.3d 627
    , 629 (6th Cir. 2006), provides a
    rational explanation for the sentence: the jury followed its instructions and sentenced
    Cauthern based on the evidence before it—not because of the prosecutor’s egregious
    remarks.
    The presumption that the jury followed the instructions it was given is bolstered
    by the fact that it sentenced Cauthern to death for Rosemary’s death but not for Patrick’s.
    The evidence before the jury much more clearly established that Rosemary’s death was
    heinous, atrocious, or cruel. Rosemary heard her husband being killed, was raped twice,
    suffered through a botched strangling, and finally was killed in a particularly gruesome
    manner. Patrick’s death, horrible as it was, did not have the same indicia of torture as
    No. 10-5759         Cauthern v. Colson                                             Page 37
    his wife’s. The jury’s decision to impose different punishments does not definitively
    answer whether the remarks affected the verdict, but the fact that the jury behaved
    rationally enough to distinguish between the circumstances surrounding the murders is
    another factor that indicates the jury was weighing the evidence and not the prosecutor’s
    improper remarks when it returned the death sentence. Together, these facts indicate
    that the prosecutor’s comments did not have a substantial and injurious effect on the
    verdict.
    Second, the Tennessee Court of Criminal Appeals was not unreasonable in
    finding insufficient prejudice from defense counsel’s failure to interview Cauthern’s
    step-siblings. Prejudice, the second prong of the Strickland analysis, is shown when
    “there is a reasonable probability that, but for counsel’s unprofessional errors, the result
    of the proceeding would have been different.” Strickland v. Washington, 
    466 U.S. 668
    ,
    694 (1985). As the state court explained, if the step-siblings had testified, their
    testimony would not have been particularly helpful to Cauthern. Each of his step-
    siblings would have testified that they had been abused by Dagmar (Cauthern’s
    grandmother), but that Cauthern was favored as the “golden child” of the family.
    Cauthern v. State, 
    145 S.W.3d 571
    , 584 (Tenn. Crim. App. 2004) (finding that Melinda
    would have testified that Cauthern was “‘the apple of [Dagmar’s] eye’”); 
    id. at 585
    (finding that Bud would have testified that Cauthern was initially the favorite child but
    would be subject to unpredictable abuse when he became older); 
    id. (finding that
    Eveann
    would have testified that she and Cauthern were “golden children”). Based on these
    findings, the Court of Criminal Appeals concluded that “[e]ven though the petitioner’s
    step-siblings undoubtedly endured abusive, isolated childhoods, it is by no means
    obvious from the proof that the petitioner’s childhood rivaled theirs.” 
    Id. at 609.
    In fact,
    testimony from the step-siblings could well have hurt Cauthern because the jury could
    have concluded that Cauthern’s step-siblings “do not manifest obvious antisocial traits
    or violent tendencies” despite having been subject to greater abuse at the hands of
    Dagmar. 
    Id. Concluding that
    there was no reasonable probability that the evidence of
    Cauthern’s childhood would have changed the jury’s imposition of the death penalty was
    not an unreasonable application of Strickland.
    No. 10-5759        Cauthern v. Colson                                           Page 38
    To be sure, the majority articulates reasonable bases for disagreeing with the
    Tennessee Supreme Court and the Court of Criminal Appeals on the two prejudice
    issues. But as the Supreme Court has repeatedly explained:
    an unreasonable application of federal law is different from an incorrect
    application of federal law. Indeed, a federal habeas court may not issue
    the writ simply because that court concludes in its independent judgment
    that the relevant state-court decision applied clearly established federal
    law erroneously or incorrectly. Rather, that application must be
    objectively unreasonable. This distinction creates a substantially higher
    threshold for obtaining relief than de novo review. AEDPA thus imposes
    a highly deferential standard for evaluating state-court rulings, and
    demands that state-court decisions be given the benefit of the doubt.
    Renico v. Lett, 
    559 U.S. 766
    , 773 (2010) (citations and internal quotation marks
    omitted).
    In a meticulous 168-page opinion, District Judge Trauger thoughtfully and
    carefully disposed of multiple arguments presented by petitioner’s counsel. I would
    affirm the judgment of the district court denying the habeas writ.
