    DIAZ, Circuit Judge:
    Gary DuBose Terry brutally murdered Urai Jackson after disconnecting her
    telephone, breaking into her home, and raping her. He was convicted and sentenced to
    death by a South Carolina jury. He appeals the district court’s grant of summary judgment
    to the respondent state officials Bryan P. Stirling and Michael Stephan on his petition for
    writ of habeas corpus, brought pursuant to 
    28 U.S.C. § 2254
    .
    Terry contends that his trial counsel provided ineffective assistance by failing to
    thoroughly investigate and present available mitigating evidence of abuse Terry suffered
    as a child and by failing to adequately question the venire during jury selection. Terry also
    argues that counsel in his state postconviction proceeding were likewise ineffective by
    failing to raise or investigate these claims.
    The district court denied Terry’s petition, holding that Terry failed to demonstrate
    cause to excuse the procedural default of the claims. We agree with the district court.
    We again accentuate the high procedural bar erected by Martinez v. Ryan, 
    566 U.S. 1
     (2012), which Terry fails to overcome because his claims are insubstantial. In so
    concluding, we exercise our discretion to reconsider issues that we implicitly resolved in
    Terry’s favor by granting his certificate of appealability. See Owens v. Stirling, 
    967 F.3d 396
    , 403 (4th Cir. 2020). Accordingly, we affirm.

    I.
    A.
    Terry’s convictions for murder, first degree burglary, first degree criminal sexual
    conduct, and malicious injury to a telephone system trace back to May 1994. As recounted
    by the Supreme Court of South Carolina:
    The victim in this case, 47 year old Urai Jackson, was found beaten to death
    in her Lexington County home on May 24, 1994. The window on the carport
    door to her home had been broken out and the telephone wires had been
    pulled from the phone box. [Jackson]’s mostly nude body was found in the
    living room, and semen was found in her vagina. She had several blunt
    trauma wounds to the head, and a number of defensive wound injuries. The
    cause of death was blunt trauma with skull fracture and brain injury.
    State v. Terry, 
    529 S.E.2d 274
    , 275–76 (S.C. 2000).
    Terry’s fingerprints were found on Jackson’s telephone box, and the semen in
    Jackson’s vagina contained Terry’s DNA. Terry also admitted to police that he had sex
    with Jackson in her home and hit her with a blunt object.
    B.
    A Lexington County grand jury indicted Terry for the crimes described above. The
    state thereafter filed notice that it would seek the death penalty.
    Terry was represented by Elizabeth Fullwood, the Lexington County Public
    Defender, and I. McDuffie Stone, a lawyer in private practice, who also served as a part-
    time prosecutor in another state judicial circuit and represented an entity that insures state
    4
    agencies and local governments. 1 They hired Vivian Massey, a mitigation specialist whom
    Fullwood had used in previous cases, to gather background and social history information
    from Terry.
    During jury selection, Fullwood questioned a juror about her ability to impose either
    a life or a death sentence, and attempted to question the juror about her views on psychiatry.
    The court sustained the state’s objection to this line of questioning.
    Fullwood then questioned the juror about mitigation more generally, but again faced
    an objection when she began a question with “one reason to lessen the sentence under the
    law in this state is the mentality—[.]” J.A. 318. Fullwood argued that the line of
    questioning was appropriate under Morgan v. Illinois, 
    504 U.S. 719
     (1992), 2 but the court
    again sustained the state’s objection. It did, however, agree to read the relevant statutory
    mitigating circumstances from S.C. CODE ANN. § 16-3-20(C)(b) 3 to the jurors and ask
    1
    Terry argued before the district court that Stone was operating under an actual
    conflict of interest because he served as a prosecutor and had government clients. Terry
    doesn’t raise this argument on appeal, however, and has thus abandoned it. See United
    States v. Al-Hamdi, 
    356 F.3d 564
    , 571 n.8 (4th Cir. 2004) (“[C]ontentions not raised in the
    argument section of the opening brief are abandoned.”).
    2
    Under Morgan, a capital defendant has the constitutional right to conduct
    sufficiently probing voir dire to discover, and exclude from the jury, prospective jurors
    who “would unwaveringly impose death after a finding of guilt.” 
    504 U.S. at 733
    .
    3
    These circumstances were that (1) “[t]he murder was committed while the
    defendant was under the influence of mental or emotional disturbance”; (2) “[t]he capacity
    of the defendant to appreciate the criminality of his conduct or to conform his conduct to
    the requirements of law was substantially impaired”; and (3) “[t]he age or mentality of the
    defendant at the time of the crime.”
    5
    whether they could consider that evidence. The court also read the relevant statutory
    aggravating circumstances from § 16-3-20(C)(a). 4
    When questioning juror Norwood Brown, who submitted a post-trial affidavit in this
    case, Stone asked:
    [I]f you are in a position of sitting on a jury and you get in the position of
    finding somebody guilty of murder and another—like a rape or a burglary—
    and then you get into a sentencing phase, can you be fair to both the State
    and the defense and consider those aggravating and mitigating circumstances
    that the judge talked about earlier with you?
    J.A. 496.
    Brown answered, “Yes, sir.” Id. Stone then asked, “So you could consider life and
    you could consider death, either way, even after you found somebody guilty?” Id. Brown
    again answered yes. Stone asked nearly identical questions of, and elicited nearly identical
    responses from, Robin Ritchie, the other juror who submitted a post-trial affidavit.
    Following a two-day presentation of evidence, and after less than two hours of
    deliberations, the jury found Terry guilty of the offenses charged in the indictment.
    C.
    1.
    Terry’s sentencing proceeding began the next day. The state’s presentation included
    evidence of Terry’s extensive criminal history and violent character.
    4
    These circumstances were that “[t]he murder was committed while in the
    commission of the following crimes or acts: (a) criminal sexual conduct in any degree; . . .
    [and] (d) burglary in any degree.” § 16-3-20(C)(a).
    6
    In 1985, Terry stole several items from a business called Imports Plus, including
    approximately eighteen items “such as sanders, things that would be utilized in a body
    shop, . . . to repair damage . . . on a vehicle.” J.A. 361. That same year, Terry stabbed a
    woman in the throat, resulting “in a conviction for assault and battery of a high and
    aggravated nature.” Id. According to the victim’s statement, after stabbing her, Terry “just
    slowly walked to the door like he hadn’t done anything. He was just so calm.” J.A. 1135.
    In 1988, Terry was convicted of resisting arrest, possessing a stolen vehicle, and
    other offenses. Terry committed additional infractions while in custody for these crimes,
    including disorderly conduct and bribery.
    The state called several character witnesses. Jeffrey Douglas Ford testified that he
    had known Terry since 1988 and had helped Terry steal cars. While working with Terry
    to provide security at a bar, Ford saw Terry hit patrons with pool cues and rocks while
    breaking up fights. Ford also saw Terry hit a patron with a beer mug after the patron spilled
    beer on Terry’s jacket.
    Tyrone Kelly testified that Terry intentionally hit his car, causing significant
    damage and nearly hitting him, following a dispute over money that Terry believed Kelly
    owed him. Kelly further testified that Terry and another man wanted the money to buy
    “something to smoke.” J.A. 363.
    While in jail awaiting trial on Jackson’s murder, Terry smashed the wall of his cell
    with a fire extinguisher. The state also presented a letter found in Terry’s cell stating that
    Terry had conspired with Johnny Brewer, an inmate housed with Terry, to confess to a
    7
    murder for which Brewer was under arrest, whereupon Brewer would be released and then
    help Terry escape.
    Angela Fedorchak testified about a violent incident involving Dianne Gibson,
    Fedorchak’s friend and Terry’s girlfriend. 5 When Terry arrived at the house where
    Fedorchak and Gibson were staying, Fedorchak told him that Gibson wasn’t there.
    Undeterred, Terry forced his way into the house. Terry hit Fedorchak with a screen door
    hard enough to slam her into a wall and cause internal bleeding for which Fedorchak
    required medical treatment. Terry then forced Gibson to leave with him.
    Gibson also testified for the state. She experienced Terry’s “hot temper” during
    their relationship and said that Terry would throw things if she didn’t do what he wanted.
    J.A. 366. After one fight, Terry left Gibson at a friend’s house and, when she arrived home,
    she discovered that Terry had “busted her answering machine, torn up pictures and thrown
    things about her room.” Id. (cleaned up). After another disagreement, Terry “threw
    [Gibson’s] kitten up against the wall and threw the T.V. off the shelf.” Id. Gibson testified,
    “[Terry] never physically abused me other than a few times just grabbing [her] by the arm,
    but . . . he controlled [her] emotionally and mentally.” Id.
    According to Gibson, Terry never held a legitimate job, stole boat and car trailers,
    and took money from each of her paychecks to buy crack. Gibson also recalled Terry
    telling her about a time when he beat a man “half to death” because he swore at Terry when
    Terry had told him to be quiet. Id.
    5
    Terry was married at the time.
    8
    Gibson read the following excerpts from letters Terry sent her from prison:
    Shit. I would not know how to change. I am me. Like I said, there is nobody
    like me and nobody will mess with me because they know I will hurt
    them. . . . I’m going to be just like I was before, maybe a little meaner than
    I was, but that’s all. . . . I need to start calming down. I am getting too old
    for all this shit. I always loved to fight. I did it so good. It felt so good to
    hurt people that was bigger than me, but that’s all behind me.
    J.A. 367.
    Gibson testified that Terry persuaded her to shoot him in the leg so that he could
    avoid going to court for back child support. She described how Terry had damaged her
    cars, once throwing a child’s toy at, and kicking in the door of, her truck, when she tried to
    leave him. Terry burned one of Gibson’s cars by “pouring lighter fluid in the dash and
    setting it on fire.” J.A. 368 (cleaned up). Gibson recalled several incidents when she tried
    to leave Terry, and he threatened to burn her home or otherwise harm her family.
    Gibson also testified about the incident Fedorchak had described. Earlier that
    evening, Gibson met up with Terry, who had been drinking. He gave her flowers and a
    bracelet. Gibson stated, “The conversation started off fine. I told him that I did not love
    him anymore, that I did not want to be with him. Then he got mad. He tried to punch out
    my passenger’s side window of my truck.” Id.
    Gibson tried to leave, but Terry opened the hood of her truck and disabled the
    engine. Terry then promised to repair the engine if Gibson rode in his car with him. She
    did, and during the ride, Terry told her that he intended to force Gibson to watch him kill
    himself. Gibson jumped out of the car, but Terry picked her up and then took her back to
    9
    her truck and fixed the engine. Gibson left and eventually met up with Fedorchak before
    returning to her house.
    Gibson then went into her bedroom, locked the door, and turned off the lights. She
    heard the altercation between Terry and Fedorchak, after which Terry broke into Gibson’s
    room, grabbed her by the arm, and told her to leave with him. Gibson did, but drove very
    slowly, and when she saw blue lights behind her truck, she stopped and jumped out.
    Gibson learned about Urai Jackson’s murder the same day that Jackson’s body was
    found. Three or four days later, Terry told her that a friend had gone to the crime scene
    and had told him that the phone box had been tampered with and that the glass on the
    carport was broken from the inside.
    Tamatha Griffin, Terry’s ex-wife, testified that Terry was physically abusive during
    their marriage and never provided well for the child they had together. Griffin filed for
    divorce on the basis of physical cruelty. She recounted the following:
    Gary told me that he had stabbed a prostitute in the neck and he had to leave.
    So he left and went to Florida. But prior to this, he would grab a hold of my
    arm. He wanted to take my car one night and I didn’t want him to take it.
    So I had the keys in my hand and he was twisting my arm and finally he got
    the keys and he said that he was going to take the car and I said, well, you
    are not going to take the car without me in it. We were going down a dirt
    road and he opened my door and tried to push me out of the car.
    He’s broken the windshield out of my stepfather’s van. My stepfather took
    me to his mother’s house and I got my car that was there and while I was
    trying to leave, he busted the windshield out of my car and the glass hit my
    face and cut my face.
    J.A. 369–70. Griffin also testified that Terry raped her during their marriage.
    10
    2.
    The state introduced statements that Terry made to the police regarding Jackson’s
    murder. Terry first told police that he had never been alone with Jackson inside her home.
    But he later claimed that he and Jackson had consensual sex inside her home, and he then
    fought with Jackson when he tried to leave against her wishes.
    The argument got pretty heated. I went to go out of the room and she grabbed
    me by the hair. I turned around and swung to get her off of me. I think I hit
    her and she went down to her knees.
    I, again, tried to walk out of the room. I got almost to the end of the hallway.
    She grabbed me from behind again. I then lost my temper. I swung back at
    her again. I then got something into my hand. It was just there in the hall.
    She could have brought it with her. I started hitting her with it. I lost my
    temper and I hit her several times. I have a bad temper.
    I then remembered leaving out of the same back door. I could have dusted
    [sic] a pane of glass on the door when I busted the door open.
    I don’t remember pulling the phone lines. I don’t remember what I did with
    the object that I used to hit Ms. Jackson. I can’t remember what it was. I
    remember that I could hold it in one hand and it wasn’t as big as a baseball
    bat.
    J.A. 370–71.
    The state also played a video of the crime scene and presented a blood spatter expert,
    who testified that “Jackson was laying on the ground or could have been no higher than
    nine inches off of the ground when she received her head wounds.” 6 J.A. 371. The state
    6
    We think the expert meant that Jackson’s head, rather than her entire body, could
    have been no more than nine inches above the ground.
    11
    then called Dr. John B. Carter, the forensic pathologist who testified during the guilt phase,
    to more fully describe Jackson’s injuries.
    Carter testified that Jackson had a swollen right thumb, which “could have happened
    warding off a blow or it could have come from having the hand on the floor one side up or
    the other side up and then being stomped on or being struck sharply with a hard object.”
    J.A. 372 (cleaned up). Jackson had other injuries to her arms consistent with defensive
    wounds, as well as extensive injuries to her right shoulder consistent with the use of two
    weapons. According to Carter, all of Jackson’s injuries were consistent with “some type
    of a prolonged struggle and probably not a one blow to the ground type of episode.” Id.
    (cleaned up).
    As to Jackson’s head wounds, Carter explained that there were “at least four
    different tracks that we can see, although, there may have been more blows superimposed
    on the original and the force was such that the skull just behind the right ear was crushed
    and depressed in multiple places.” J.A. 373. Jackson’s skull “was crushed and smashed
    inward somewhat like punching against an eggshell.” Id. Jackson, said Dr. Carter, was
    found with her legs spread apart, with semen matched to Terry in her vaginal canal. He
    explained that “the position of the victim’s body is very characteristic of positions the
    victims are found in that have been engaged in sexual activity or assault at the time of
    death. The legs are spread apart and death occurs and they stay that way.” Id.
    3.
    In mitigation, Terry presented evidence of his upbringing and of damage to his
    brain. Terry’s mother, Patricia, testified that, when Terry was about four years old, his
    12
    father, Bill Terry, was injured in an accident and could no longer work. Though Bill
    received workers’ compensation, it wasn’t enough to support the family. Patricia thus
    worked outside the home, first at a sewing room and then at a textile mill.
    The accident not only made finances tight, but also changed Bill’s personality,
    making him more irritable and unable to tolerate the noise of children playing. According
    to Patricia, Bill would leave the room when the children were playing. But she said nothing
    about him becoming angry at the children, let alone abusing them.
    Patricia explained that Terry, the youngest of five, was a “loner” as a child and was
    content to play by himself. J.A. 686. Terry didn’t participate in any traditional childhood
    activities, such as scouting or little league, because he “didn’t have an attention span to sit
    . . . for longer periods.” J.A. 687. In the second or third grade, Terry was tested and
    determined to have a learning disability and be “borderline retarded.” Id. He was placed
    in special education classes, but his parents didn’t tutor him or otherwise help him
    academically.
    Patricia testified that, starting around age 13, Terry “and his brothers fought a
    lot. . . . And even though he’s the smallest of them, he would still hang in there.” J.A. 688.
    Terry also “had a lot of run-ins with his dad.” Id. However, Patricia claimed that none of
    the fights required intervention by law enforcement. 7
    7
    A defense expert later testified that Terry’s parents had his brothers arrested for
    abusing him.
    13
    One night, when Terry was 13, he blocked the door of his bedroom with a dresser,
    wrapped himself “cocoon style” in a blanket, and inhaled the fumes from a can of glue
    remover and a tube of “airplane glue.” J.A. 689–90. Patricia and Bill forced their way into
    Terry’s bedroom and found him unconscious. Terry’s parents were able to revive him by
    taking him outside, but he was disoriented when he regained consciousness. Aside from
    having Patricia’s brother-in-law, who was a doctor, visit Terry at their house the following
    day, Terry’s parents didn’t seek any medical or mental health treatment for him.
    When Terry was about 14, he got into a fight with one of his brothers, during which
    he threw a brickbat through the window of a van that his brother was restoring. Terry’s
    father tried to break up the fight, but when Terry “came at him,” Bill swung a board at
    Terry with enough force to break Terry’s collarbone. J.A. 692.
    Patricia also testified to symptoms of apparent internal injuries and brain damage in
    Terry following a fall from a tree while working for a tree-trimming company in Florida,
    where he fled after committing the 1985 stabbing. Terry repeatedly coughed up blood
    while in jail for the stabbing and following his return home, though doctors were unable to
    determine the cause of the bleeding. Patricia also stated that:
    I’ve seen him stagger before. I’ve seen him go do something and just
    completely forget what he was doing. And he’s—it’s like I said, he just
    staggers. I’ve never seen him completely black out, but I have seen him
    forget what he was doing or just completely stop and turn around. And
    they’ve given him all kinds of medicine. They’ve even taken him to the
    hospital and put medicine in his veins for migraine headaches and . . . they
    stop for a while and then they come right back.
    J.A. 702.
    14
    Bill Terry described an incident when Terry, age 10 or 12 at the time, intervened
    when neighborhood children “started cursing . . . and throwing rocks” at Bill. J.A. 731.
    Bill said that Terry helped around the house and was a “good kid.” J.A. 732. Bill did not,
    however, testify to other mitigating circumstances in Terry’s life beyond affirming his
    wife’s testimony that his ability to provide for the family and to tolerate the noise of
    children playing diminished after his accident.
    Lou Ann Smith Terry, Terry’s wife and the mother of four of his children, told the
    jury that Terry had a loving relationship with his children and that, despite his actions, she
    continued to love him. She also pled with the jury for Terry’s life.
    On cross, the state confronted Ms. Terry with statements she had made during a
    psychosocial assessment of Terry as part of his admission to a hospital for drug treatment.
    Among these were assertions that Terry “lies compulsively,” “seems to have no
    boundaries,” is “very manipulative,” has a “violent temper,” “liked having his own way”
    or was “spoiled,” “is very immature and dependent,” “does not see himself as an addict or
    an alcoholic,” and “shows no concern for the rights or needs of . . . his wife or others.” J.A.
    749–50. Ms. Terry did not deny making the statements, but could recall only some of
    them.
    Counsel also presented four expert witnesses: Jan Vogelsang, an expert in social
    work; Dr. Robert Deysach, an expert in clinical neuropsychology; Dr. David Bachman, an
    expert in behavioral neurology; and Dr. Donna Schwartz-Watts, an expert in forensic
    psychiatry.
    15
    Vogelsang explained the relationship between Terry’s upbringing and brain
    damage. Terry “was born to parents whose own lives and circumstances of their lives had
    made it very difficult for them to parent effectively and for that reason, they had great
    difficulty providing any more than very basic needs for their children. Especially[] after
    his father’s accident.” J.A. 769–70.
    According to Vogelsang, Terry “did have some special developmental needs as well
    and there were no resources available for those and no family members close by who could
    . . . or who did step in and take over to help this family.” J.A. 770. Vogelsang told the jury
    that one side of Terry’s family has a history of alcohol abuse, and there is a pattern
    throughout the family of “some rather unusual medical problems” and “learning and
    emotional problems.” Id. Vogelsang also said:
    [Terry] has a documented history of learning disabilities and certainly a
    history with . . . [in]attentiveness[,] impulsivity, poor judgment, explosive
    outbursts and other behavioral indications that later have turned out to be
    attributable to a medical condition that causes changes in his behavior.
    . . . . His ability to control these outbursts, to restrain his behavior, to forecast
    consequences, to learn from experience are greatly impaired. . . .
    . . . [But], with medical intervention, it is entirely possible that he will be able
    to restrain himself, control his behavior and adapt to prison life.
    J.A. 770–71.
    Vogelsang interviewed Terry four times and also spoke with Terry’s wife, mother,
    father, two sisters, two brothers, sister-in-law, former girlfriend, ex-wife, two sons,
    daughter, two aunts, uncle, great aunt, and great uncle. Vogelsang characterized Terry’s
    parents as “the poster children for bad luck” and stated, “I think they did care. They just
    16
    simply either did not know what to do or did not have the energy to do it.” J.A. 785–86.
    Notwithstanding Terry’s father breaking Terry’s collarbone with a board and his brothers
    being arrested at his parents’ behest for abusing him, Vogelsang explained:
    [I do not mean to] imply that family violence was the same in this family as
    it is in a lot of families because that’s not what I found here. There is some
    violence. I would not say it’s the kind of pervasive violence you find in a lot
    of homes where battering takes place. But certainly, at an early age, I think
    [Terry] was already probably giving signs and cues that something was
    terribly wrong.
    J.A. 784.
    According to Vogelsang, Terry’s parents failed to seek help for him after they
    discovered him inhaling glue and that, when Terry was eight, he observed an older brother
    inhale gasoline fumes, also with no parental intervention. Though Vogelsang didn’t say
    that Terry suffered significant abuse, she did testify that Terry’s older brothers and his
    sister had all lost custody of their children because they either abused or neglected them.
    Vogelsang opined, “Because we have given so much attention to physical and sexual
    abuse, . . . we have not given enough attention to the impact of neglect on children and that
    . . . is one of the keys for children ending up in the criminal justice system.” J.A. 783–84
    (emphasis added).
    Next up in mitigation was Dr. Deysach, who testified that, based on various tests of
    Terry’s cognition and behavior, Terry had an abnormality in the right frontal lobe of his
    brain and that Terry’s behavioral abnormalities were consistent with his findings of damage
    to this area of the brain. Deysach’s findings were also consistent with a diagnosis Terry
    had received in 1994 of organic explosive disorder, a condition which interfered with
    17
    Terry’s ability to regulate his behavior, particularly when he was under emotional strain.
    Deysach concluded that Terry had a “neuropsychological deficit.” J.A. 825.
    Dr. Bachman showed the jury scans of Terry’s brain which indicated an area of
    reduced activity in his right frontal lobe. Bachman then explained:
    When somebody has an abnormality [sic] function in that part of the brain,
    there are two sets of problems that you see. On the one hand, they have
    difficulties on certain types of testing such as [those administered by] Dr.
    Deysach . . . .
    The other thing that we know is that people who demonstrate those sorts of
    abnormalities . . . also frequently have other kinds of behavioral problems as
    well. And those behavioral problems include such things as irritability,
    impulsivity, aggressive behavior, explosive aggressive behavior, poor
    planning in terms of thinking about the [repercussions] of behavior[,] and
    these are very typical of patients who have had lesions such as head injury or
    other such abnormalities of that part of the brain.
    So the fact that he has the . . . abnormality in the neurospect scan, the fact
    that he has the abnormality on the neuro-psyc[h] testing, it’s very, very strong
    evidence that you would also expect to find these other behavioral problems.
    J.A. 843. Bachman affirmed that his findings were consistent with Terry’s earlier diagnosis
    of organic explosive disorder and explained that patients with this type of brain injury
    “don’t necessarily come in conflict with the law, but they sure have come in conflict with
    their family.” J.A. 844.
    Dr. Schwartz-Watts diagnosed Terry with an “organic mental disorder” not
    otherwise specified. J.A. 867. She told the jury:
    [I]t’s a major mental disorder and it’s organic in nature, meaning that it
    comes from the brain, brain damage or dysfunction in the brain compared to
    chemical imbalances or personality disturbances and it affects his thinking,
    his feelings and his behavior.
    ....
    18
    The way it affects his thinking, people with this type of brain damage, as
    demonstrated by Dr. Deysach and Dr. Bachman, and also consistent with my
    clinical findings, they can at times become suspicious and paranoid.
    ....
    And then in terms of behavior, they can be quite aggressive, explosive. They
    can have sexual indiscretions. They can be very impulsive, very, very
    impulsive people.
    J.A. 867–68. Schwartz-Watts also stated that the aggravating circumstances the state
    presented were consistent with her findings.
    In their closing arguments, Terry’s lawyers emphasized the impact of Terry’s brain
    damage on his violent behavior. Fullwood and Stone both stated that Terry’s parents were
    not at fault for his behavior. Fullwood argued that Terry’s parents “tried hard,” pointed to
    “their pain and their shame,” and said that there was “no reason to hurt them more” by
    executing Terry. J.A. 897.
    After deliberating for a little over an hour, the jury recommended that Terry be
    sentenced to death. The court imposed that sentence, as well as consecutive sentences of
    life imprisonment for first degree burglary, thirty years for first degree criminal sexual
    conduct, and ten years for malicious injury to a telephone system.
    D.
    Terry appealed and the Supreme Court of South Carolina affirmed. State v. Terry,
    
    529 S.E.2d 274
     (S.C. 2000), cert. denied sub nom. Terry v. South Carolina, 
    531 U.S. 882
    (2000). Terry thereafter sought postconviction relief in state court. Terry’s counsel raised
    multiple grounds for relief concerning trial counsel’s performance, none of which are at
    issue here. Following an evidentiary hearing, the state trial court denied Terry’s application
    19
    for postconviction relief and dismissed it with prejudice. The state Supreme Court
    affirmed. Terry v. State, 
    714 S.E.2d 326
     (S.C. 2011), cert. denied sub nom. Terry v. South
    Carolina, 
    565 U.S. 1206
     (2012).
    E.
    Terry next pursued habeas relief in federal court. 8 His federal habeas petition raised
    five grounds for relief, two of which he pursues on appeal:
    III. Petitioner’s rights to the effective assistance of counsel and to a fair and
    impartial jury as guaranteed by the Sixth and Fourteenth Amendments to the
    United States Constitution was [sic] violated by trial counsel’s failure to
    conduct adequate and appropriate voir dire or to adequately establish a record
    and appropriately object in order to preserve the issue for appellate review.
    ....
    IV. Petitioner’s right to the effective assistance of counsel as guaranteed by
    the Sixth and Fourteenth Amendments to the United States Constitution was
    violated by trial counsel’s failure to develop evidence supporting a defense
    of guilty but mentally ill and failing to adequately investigate and present
    mitigation evidence during the trial and sentencing when trial counsel failed
    to present substantial and highly mitigating evidence of Gary Terry’s
    childhood abuse.
    J.A. 31, 35. Both grounds were procedurally defaulted, because Terry’s counsel in the
    state postconviction proceeding didn’t raise them.
    Terry attached to his petition several affidavits (including from two of the experts
    who testified at trial) and other documentary evidence of childhood abuse that, he argues,
    trial counsel were deficient in failing to uncover and present as mitigating evidence. Terry
    8
    Terry also sought to exhaust his state remedies in a contemporaneously filed
    application for postconviction relief in state court. But the state court dismissed Terry’s
    application as time-barred and improperly successive.
    20
    also attached affidavits from two jurors who say that they didn’t consider a life sentence
    and that the jury didn’t discuss giving Terry a life sentence during deliberations. Finally,
    Terry presented affidavits from his trial and state postconviction counsel to show that
    counsel had no strategic reason for failing to investigate or present evidence of abuse.
    Terry’s submission to the district court painted a picture of a childhood marred by
    his father’s abuse. Some of the evidence appears in the notes of the experts retained by
    trial counsel. Massey’s notes from a pretrial interview of Terry record the following
    description of Terry’s childhood:
    Discipline: Gary stated, “My daddy beat the shit out of me with a belt.” He
    explained that his daddy has health problems (burned, busted back,
    migraines) and he has a temper. He (daddy) whipped hard enough for the
    whelps [sic] to bleed. He (daddy) slapped him (Gary) on his face, on the side
    of his head or whatever he could reach when he got mad. His daddy would
    cuss him when he got blamed for doing something. He said, “My brother
    Johnny would do stuff and blame it on me and I would catch hell for it.” All
    of the children got whipped like that.
    Gary remembered one time when he was in high school (16–17 years old)
    and was talking on the telephone at home. His daddy came by and said
    something . . . the cussing started and Gary tried to run away. His daddy hit
    him across the back with something and broke his shoulder blade. Gary
    remembers being taken to either Richland or Baptist Hospital.
    Gary said his mother was usually home when all this was going on but she
    tried to stay out of the way. One time she got in between them and got hit.
    His mother didn’t discipline him—she left it up to his daddy.
    J.A. 55.
    Vogelsang’s handwritten notes from the interviews she conducted also refer to
    abuse. Terry’s sister-in-law, Patty Terry, reported that “Patricia step[ped] in to stop Bill
    beating boys and would get it” and also that “Bill saw kids as workhorses . . . not allowed
    21
    to play.” J.A. 58, 345. Vogelsang’s notes following her interview with Terry’s brother,
    Billy Terry, reflect: “Daddy tore everyone up including him if Mom had to be awakened”;
    “Strap—hung behind door”; “couldn’t go to school—didn’t want teacher to see marks.”
    J.A. 345. From her interview with Faye Servoss, Terry’s sister, Vogelsang noted: “Fa [sic]
    wld tie kids to tree in front yard & have beat each other”; “Dad beat before accidents”;
    “Daddy made them fight each other”; and “Billy worked kids to death . . . like dogs.” J.A.
    70, 75, 345–46.
    In Vogelsang’s post-trial affidavit, she states, “[I]t is apparent that Gary and his
    siblings suffered significant abuse at home. It would have been typical of me to make this
    known to the attorneys and to stress the impact of trauma on development.” 9 J.A. 78.
    Vogelsang does not, however, have any memory of this case, which, she assumes, was
    because Terry’s trial team was not “active and cohesive.” 
    Id.
     Vogelsang explained that
    the lack of testimony concerning Terry’s abuse must have been attributable to “the lack of
    a true team effort, lack of funding, or trial counsel specifically instructing [her] not to talk
    about the abuse, or a combination of all three.” J.A. 79. But she dismissed lack of funding
    as a possible reason, because her professional ethics code would have required her to work
    9
    Because Vogelsang’s post-trial affidavit contradicts her trial testimony concerning
    the severity of the childhood abuse Terry suffered and the greater importance of neglect to
    Terry’s development, it doesn’t establish a genuine issue of material fact at summary
    judgment. See Erwin v. United States, 
    591 F.3d 313
    , 325 n.7 (4th Cir. 2010) (“[I]t is well
    established that a genuine issue of fact is not created where the only issue of fact is to
    determine which of the two conflicting versions of [an affiant’s] testimony is correct.”
    (cleaned up)). See also Rohrbough v. Wyeth Lab'ys, Inc., 
    916 F.2d 970
    , 976 (4th Cir. 1990)
    (holding that an expert’s affidavit which contradicted his deposition testimony did not
    create an issue of fact at summary judgment).
    22
    on the case, once retained, even if she had not been paid. Vogelsang also doesn’t remember
    state postconviction counsel speaking to her about the case.
    In her affidavit, Patricia Terry states that Bill, Terry’s father, “whipped the children
    with a belt almost daily.” J.A. 82. Terry’s father prohibited the children from playing
    outside, sometimes making them work until 10:00 at night. Patricia also provided an
    account of Bill breaking Terry’s collarbone inconsistent with her account at Terry’s
    sentencing proceeding (while indicating that she did not witness the actual incident):
    Bill used to have the children “fight it out” among themselves. One day,
    when Gary was between 12–14 years old, he and Johnny were fighting in the
    garage area. Bill was there, too, but did not stop the fight. Johnny is much
    bigger and stronger than Gary. Gary picked up a brick and threw it at Johnny.
    The brick broke the windshield of Bill’s car and then Bill hurt Gary. He
    broke his collarbone, and I think he did so by hitting him with a board that
    was in the garage. I was at work when this happened.
    J.A. 83.
    Patricia claimed that Bill would throw out the children’s dinner if they were served
    before he was or if he didn’t like what she cooked for dinner. Bill often threatened to “blow
    [her] brains out” in front of the children. J.A. 85. Patricia further explained, “I did not
    testify about the information included in this affidavit. I simply answered the questions
    asked of me and no one asked about these things while I was on the witness stand.” 
    Id.
    Patricia did not, however, say that she discussed this information with Terry’s attorneys.
    In a lengthy affidavit, Faye Terry Servoss, Terry’s older sister (who was not a
    witness at Terry’s trial), testified to her father’s significant abuse of various family
    members, including severe beatings, animal torture, and seeing her father force her mother
    to eat a pack of cigarettes because he was angry about her smoking. Faye also testified that
    23
    her mother said, “that one’s ruined, that’s okay, we’ve got another” to her father after a
    neighborhood boy raped her when she was a child. J.A. 87 (cleaned up). But the only
    incident relating to Terry that she described in her affidavit was his father breaking Terry’s
    collarbone. Faye also stated that she would have testified at trial to the abuse if she had
    been subpoenaed.
    Charles Register, Patricia Terry’s brother, provided a brief affidavit describing
    Terry’s father’s abuse of his wife and children. Register testified that he saw Terry’s father
    “viciously beat” Terry with a stick when Terry was six or seven years old. J.A. 94. Register
    also testified that “[he] was available and would have testified to these events had [he] been
    contacted by defense counsel.” J.A. 95.
    Finally, Francis Terry, the former wife of Terry’s older brother Billy, submitted an
    affidavit in which she testified to severe abuse that Billy inflicted upon her and one beating
    that Billy told her his father had given him. But she also said that, though Terry’s father
    was “hard” and “real strict,” she never saw him hit his children. J.A. 98.
    In her affidavit, Dr. Schwartz-Watts stated, “I did not review, because I was not
    provided, detailed interviews with various family members conducted by defense counsel’s
    mitigation investigator, Vivian Massey, nor did I review, because I was not provided, any
    of the materials assembled by Jan Vogelsang, the social worker hired by defense counsel.”
    J.A. 101.
    After receiving this information and the affidavits of family witnesses from habeas
    counsel, Schwartz-Watts reexamined Terry in May 2012. Had Schwartz-Watts known
    about the abuse Terry suffered, she would have testified at trial that Terry suffered effects
    24
    from trauma, including missing memories, intrusive thoughts of childhood abuse, and
    inability to form healthy relationships. According to Schwartz-Watts, “[t]his information
    is mitigating in its own right, but is also significant with respect to significant brain
    dysfunction, as the abuse may have actually contributed to the dysfunction.” J.A. 102.
    “Terry,” she said, “had more neurological dysfunction than any patient I have ever
    evaluated, including those prior to 1997 and since.” 
    Id.
     Dr. Schwartz-Watts didn’t recall
    hearing from Terry’s counsel in the state postconviction proceeding, although she knew
    and worked with these attorneys on other cases.
    In her affidavit, Fullwood says that “[i]f the evidence of Gary Terry’s substantial
    physical abuse was not provided to Dr. Schwartz-Watts it should have been.” J.A. 47.
    Fullwood also did “not recall making any strategic decision to limit the mitigation
    testimony of Gary’s family members or to avoid presentation of evidence that he had
    suffered significant abuse as a child.” 
    Id.
     She stated that it was her “intent to present all
    of the evidence of that nature that [she] could and all that [she] was aware of was
    presented.” 
    Id.
     Fullwood also didn’t discuss the case with Terry’s counsel in the state
    postconviction proceeding before testifying.           She deemed this unusual, since
    postconviction counsel generally interview trial counsel before calling them to the witness
    stand.
    Terry’s postconviction counsel filed affidavits stating that they spoke with Terry’s
    parents and one of his ex-wives but did not develop additional mitigation evidence from
    these conversations. Their affidavits do not, however, specify whether they questioned
    25
    Terry’s family members about abuse or indeed what they discussed with Terry’s family
    members during the interviews.
    Postconviction counsel didn’t interview or speak with Massey or any of the four
    expert witnesses who testified at trial. They don’t recall interviewing any jurors in Terry’s
    trial. If they had known of the abuse Terry suffered as a child, they would have argued that
    trial counsel were ineffective for failing to present this issue to the jury.
    The affidavits of jurors Brown and Ritchie assert that the jury didn’t consider a life
    sentence for Terry. See J.A. 49 (Brown testifying, “[W]e made the [sentencing] decision
    easily and were all in agreement. We did not discuss giving [Terry] a life sentence.”); J.A.
    51 (Ritchie testifying, “We did not discuss giving [Terry] a life sentence.”). Brown said,
    “Based on the fact that [Terry] committed a murder plus rape and burglary, there was
    nothing he could have said or done to make me give him a life sentence. I believe the death
    penalty is the right punishment for murder if there are also other crimes.” J.A. 49. Ritchie
    stated that “the defense lawyers’ attempts to evoke sympathy did not work” and explained,
    “[T]he evidence regarding his brain injury did not impact me. What I cared about was
    whether he knew right from wrong, and he did, so in my opinion he did not deserve a life
    sentence.” J.A. 51.
    The district court granted summary judgment to the state on Terry’s habeas petition
    and adopted the magistrate’s 144-page Report and Recommendation as the order of the
    court. Terry v. Stirling, No. 4:12-1798-RMG, 
    2019 WL 4723345
    , at *1 (D.S.C. Sept. 26,
    2019). The district court also denied Terry’s request for an evidentiary hearing. 
    Id. at *9
    .
    26
    Terry, said the district court, had “not made specific factual allegations that, if true,
    would entitle him to habeas relief and ha[d] failed to demonstrate the substantiality of his
    underlying ineffective assistance of counsel claims.” 
    Id.
     The district court arrived at this
    conclusion for four related reasons: (1) Terry’s trial counsel presented some evidence of
    Terry’s childhood abuse; (2) Terry presented no evidence that trial counsel knew more
    information about the abuse than they presented; (3) any deficiencies in trial counsel’s
    presentation were attributable to their experts’ failure to inform them of childhood abuse
    Terry suffered, for which trial counsel cannot be faulted; and (4) the record suggests that
    Vogelsang, counsel’s expert in social work, did not deem the abuse significant when she
    testified at Terry’s sentencing. 
    Id. at 12
    .
    The district court also held that Terry’s trial counsel conducted an adequate voir
    dire. It noted that counsel asked both jurors Brown and Ritchie 10 whether they could
    consider either a life or a death sentence depending on the circumstances, even after finding
    Terry guilty of murder and other crimes, and both jurors answered in the affirmative. 
    Id. at *11
    . Terry, said the district court, “was permitted to do exactly what Morgan requires,
    namely, he inquired whether each of these jurors had predetermined whether or not to
    impose the death penalty, with each one confirming, with the benefit of knowing both the
    statutory mitigating factors and that they would have already found Petitioner guilty of
    murder plus an additional criminal act, that they could impose either a sentence of life in

    The district court refers to Brown and Ritchie as Juror #35 and Juror #214
    respectively.
    27
    prison or death.” 
    Id. at *12
    . And the trial court didn’t improperly curtail counsel’s voir
    dire, because South Carolina law prohibited the questions that counsel wished to ask
    regarding the jurors’ views of psychiatry. 
    Id.
     at *11–*12.
    This appeal followed.
    II.
    “We review the district court’s denial of habeas relief on summary judgment de
    novo.”     Sigmon v. Stirling, 
    956 F.3d 183
    , 191 (4th Cir. 2020).            “[U]nder certain
    circumstances, including raising a claim under Martinez, a petitioner may excuse a state
    court procedural default.”

    court considers those claims de novo.” 
    Id.
    “We review a district court’s decision to deny a habeas petitioner an evidentiary
    hearing for abuse of discretion.” Id. at 198. “In deciding whether to grant an evidentiary
    hearing, a federal court must consider whether such a hearing could enable an applicant to
    prove the petition’s factual allegations, which, if true, would entitle the applicant to federal
    habeas relief.” Schriro v. Landrigan, 
    550 U.S. 465
    , 474 (2007).
    “Generally, if a claim is procedurally defaulted in state court, federal habeas review
    is barred ‘unless the prisoner can demonstrate cause for the default and actual prejudice.’”
    Sigmon, 956 F.3d at 198 (quoting Coleman v. Thompson, 
    501 U.S. 722
    , 750 (1991)). “And
    ineffective assistance of state post-conviction counsel generally cannot establish cause for
    the default because there is no constitutional right to an attorney in state post-conviction
    proceedings.” 
    Id.
     (cleaned up). “However, when state law requires ‘claims of ineffective
    28
    assistance of trial counsel [to] be raised in an initial-review collateral proceeding’ and not
    on direct review—which South Carolina law does—procedural default does not bar federal
    habeas review of ‘a substantial claim of ineffective assistance at trial if, in the initial-review
    collateral proceeding, there was no counsel or counsel in that proceeding was ineffective.’”
    
    Id.
     (quoting Martinez, 
    566 U.S. at 17
    ).
    “Accordingly, to invoke Martinez and obtain federal habeas review of a claim

    or absent, and that the underlying ineffective assistance of [trial] counsel claim is
    substantial.” 
    Id.

    566 U.S. at 14

    , 104 (2011)
    (cleaned up). As we recently held:
    29
    [A] state prisoner satisfies Martinez by showing, first, that initial
    postconviction counsel performed deficiently, under the first prong of
    Strickland, by failing to exhaust the underlying ineffective-assistance-of-
    trial-counsel claim, but not that said counsel’s deficient performance was
    prejudicial, under the second prong of Strickland; and second, that the
    underlying claim is substantial, or has some merit, with respect to both
    prongs of Strickland.
    Owens, 967 F.3d at 423.
    A.
    We first turn to Terry’s argument that his trial counsel was deficient under
    Strickland for failing to present additional evidence of childhood abuse. 11 As we explain,
    we hold that this claim is insubstantial under Martinez.
    1.
    We begin our analysis by considering the actual performance rendered by trial
    counsel in sentencing. Though unsuccessful in persuading the jury, Terry’s lawyers
    presented a coherent mitigation case with a clear theory for why the jury should have voted
    for life.
    First, counsel attempted to humanize Terry and presented extensive evidence of his
    difficult childhood through testimony from his mother, father, and wife. Terry’s mother
    testified to violent fights between Terry and his older brothers, Terry’s possible teenage
    suicide attempt when he blocked the door of his room with a dresser and inhaled glue fumes
    until he lost consciousness, and the incident in which Terry’s father broke Terry’s
    collarbone with a board during a fight between Terry and one of his brothers. Indeed,
    Given our disposition, we don’t address whether state postconviction counsel
    11
    were ineffective in failing to exhaust the claim.
    30
    Terry’s father breaking his collarbone is one of the few specific instances of abuse against
    Terry to which the affiants testify. See J.A. 83 (Terry’s mother Patricia describing this
    incident); J.A. 90 (Faye Servoss, Terry’s older sister, describing this incident, the only
    specific instance of abuse against Terry she mentions in her 36-paragraph affidavit).
    Terry’s mother also testified to obvious symptoms of brain damage, including
    headaches and times when Terry would stagger and forget what he was doing while doing
    something. Terry’s father then testified to occasions when Terry helped his family, and
    Terry’s wife testified to Terry’s loving relationship with his children and the pain that his
    execution would inflict on them.
    Terry’s counsel didn’t limit their mitigation case to testimony from his family
    members, however. They also called four experts, all of whom presented unrebutted
    evidence of Terry’s brain damage and its effects on his behavior—particularly his ability
    to control his impulses and make decisions. Vogelsang, who interviewed multiple family
    members and also interviewed Terry four times, testified at length to the impact of Terry’s
    neglectful, and at times violent, childhood on his character. Then in closing, Terry’s
    counsel argued that the jury should spare his life, because executing him would inflict
    unnecessary additional pain and shame on his family, and because Terry’s brain damage
    diminished his responsibility for his violent behavior.
    2.
    Terry’s new lawyers now characterize Terry’s childhood as far grimmer than even
    the less-than-idyllic picture that trial counsel painted. With the benefit of hindsight and
    31
    following an adverse sentence, Terry argues that trial counsel were deficient for failing to
    present this additional evidence of childhood abuse.
    But the district court rejected this argument, and for good reason. The evidence
    shows that counsel, through the defense team, discovered and presented relevant
    information about abuse, particularly the incident in which Terry’s father broke his
    collarbone with a board. See J.A. 692 (where Patricia describes this incident in her trial
    testimony).
    Counsel also intended to present all evidence regarding abuse to the jury. And they
    don’t say now that they knew about the evidence of abuse in the notes prepared by Massey
    and Vogelsang.
    That said, it appears that Fullwood did have Massey’s typewritten notes in her case
    file. Indeed, in the state postconviction proceeding, Fullwood referred to these notes in
    answering questions about information that Terry provided the trial team during the team’s
    investigation. But Fullwood didn’t testify (nor was she asked) whether she reviewed those
    portions of Massey’s notes describing Terry’s childhood abuse.
    Though it’s unclear whether Vogelsang’s handwritten notes (which are difficult to
    read in places) were in counsel’s file, Vogelsang presumably reviewed them and concluded
    that neglect had a greater impact on Terry’s behavior than the abuse of which she was
    aware. Given that Vogelsang interviewed Terry multiple times and spoke with several of
    Terry’s family members (including all but one of the relatives that have submitted post-
    trial affidavits), counsel had no reason to believe that Vogelsang’s opinion was unfounded
    or that Vogelsang failed to fully inform them of the circumstances of Terry’s childhood.
    32
    While counsel may not abdicate their responsibility to investigate their client’s case,
    it’s not unreasonable or contrary to prevailing professional norms for counsel to rely on a
    qualified mitigation investigator or other experts. See Rhode v. Hall, 
    582 F.3d 1273
    , 1283
    (11th Cir. 2009). 12 Terry’s counsel were also entitled to rely on Vogelsang’s expert opinion
    concerning the causes of Terry’s behavior. See Wilson, 155 F.3d at 403 (holding that, to
    be reasonably effective, trial counsel is not required to “second-guess” their expert’s
    opinions).
    But even if counsel could be faulted for not highlighting evidence of Terry’s abuse
    more forcefully, they were by no means constitutionally deficient—particularly in light of
    the robust mitigation case that was presented. We agree with our sister circuit that
    “perfection is not the standard of effective assistance.” Waters v. Thomas, 
    46 F.3d 1506
    ,
    1514 (11th Cir. 1995) (en banc). And failures to present or develop certain evidence don’t
    necessarily rise to deficient performance or prejudice under Strickland. See Byram v.
    Ozmint, 
    339 F.3d 203
    , 210–11 (4th Cir. 2003) (trial counsel not deficient for failing to
    obtain petitioner’s adoption records, which might have provided additional evidence that
    he suffered from fetal alcohol syndrome and more evidence of childhood trauma, when
    counsel made reasonable efforts to obtain the records and otherwise presented a robust
    mitigation case concerning petitioner’s “troubled childhood and adolescence”).
    12
    Nor is there a right to effective assistance of expert witnesses or mitigation
    investigators. See Wilson v. Greene, 
    155 F.3d 396
    , 401 (4th Cir. 1998) (“The Constitution
    does not entitle a criminal defendant to the effective assistance of an expert witness.”).
    33
    Now, with the benefit of hindsight, Terry argues that counsel should have
    emphasized abuse and de-emphasized neglect in their mitigation case.            But “[t]he
    widespread use of the tactic of attacking trial counsel by showing ‘what might have been’
    proves that nothing is clearer than hindsight—except perhaps the rule that we will not judge
    trial counsel’s performance through hindsight.” Waters, 
    46 F.3d at 1514
    . We are satisfied
    that counsel conducted a reasonable investigation “and they cannot be held accountable for
    information Petitioner and his family failed to provide or their experts failed to convey.”
    Terry, 
    2019 WL 4723345
    , at *14.
    The cases on which Terry relies to contend otherwise are distinguishable. In
    Rompilla v. Beard, 
    545 U.S. 374
    , 383 (2005), for example, the Supreme Court held that
    counsel were deficient for failing to review the record of the defendant’s prior conviction
    for rape and assault. The file at issue, which was a readily available public record,
    contained the transcript of the rape victim’s testimony that counsel knew the prosecutor
    intended to use as aggravating evidence at the sentencing phase of Rompilla’s trial. 
    Id.
    If counsel had reviewed the file, which also contained Rompilla’s prison records
    from his incarceration for that prior conviction, they would have “found a range of
    mitigation leads that no other source had opened up,” including evidence that Rompilla
    was raised in a “slum environment,” suffered from various psychological disorders, and
    had test scores indicating a third-grade level of cognition. 
    Id.
     at 390–91. These records
    “would have destroyed the benign conception of Rompilla’s upbringing and mental
    capacity defense counsel had formed from talking with Rompilla himself and some of his
    family members, and from the reports of the mental health experts.” 
    Id. at 391
    .
    34
    The facts of Rompilla are far removed from Terry’s case. For starters, Terry neither
    alleges nor shows that trial counsel failed to examine records they knew, or should have
    known, that the state would use as aggravating evidence. He argues instead that counsel
    missed “numerous red flags,” Appellant’s Br. at 32, which should have alerted them to the
    abuse Terry suffered as a child, that they had no strategic reason to limit their investigation
    or presentation of this mitigating evidence, and that their failure to present the evidence of
    abuse they already had “suggest[s] that their incomplete investigation [and presentation]
    was the result of inattention, not reasoned strategic judgment.” Id. at 31 (quoting Wiggins,
    
    539 U.S. at 534
    ).
    But the record is, at best, ambiguous as to whether Terry’s counsel failed to review
    the evidence of abuse they had. And even if they did, this error doesn’t amount to deficient
    performance, particularly when juxtaposed with the robust mitigation case that they did
    present.
    Terry also cites to Winston v. Pearson, 
    683 F.3d 489
     (4th Cir. 2012) for the related
    propositions that attorneys are “obligated to be familiar with readily available documents
    necessary to an understanding of [their client’s] case,” and forbidden from relying on an
    expert to “ascertain their import.” 
    Id. at 505
     (cleaned up). There, we held that Winston’s
    counsel were deficient for failing to read his school records—which revealed an IQ low
    enough to qualify him as intellectually disabled, thus barring his execution—and weren’t
    entitled to rely on an expert to ascertain the import of these records.
    But Winston is distinguishable from this case for the same reasons Rompilla is: The
    records at issue were easy to obtain and required no effort on trial counsel’s part to
    35
    decipher. Winston is also distinguishable because counsel’s errors there led them to fail to
    raise the claim that Winston’s intellectual disability categorically barred a death sentence.
    683 F.3d at 492–93. Here, by contrast, the alleged deficiencies in not presenting the
    evidence of physical abuse merely failed to bolster an already strong mitigation case that
    included some evidence of abuse. And none of this evidence would have categorically
    barred the imposition of a death sentence.
    Terry also relies on Abdul-Salaam v. Secretary of Pennsylvania Department of
    Corrections, 
    895 F.3d 254
     (3d Cir. 2018), in which our sister circuit deemed counsel
    deficient for failing to investigate significant evidence of mitigating childhood abuse. But
    counsel in Abdul-Salaam presented a sum total of three witnesses, all family members,
    during the sentencing phase; didn’t interview multiple other family members who would
    have testified to severe abuse; didn’t call any mental health experts to the stand (and could
    give no cogent explanation for this decision); and didn’t try to obtain any of Abdul-
    Salaam’s school or juvenile records (which contained additional evidence of his troubled
    childhood). 
    Id. at 258, 261
    .
    Here, by contrast, counsel presented four expert witnesses—all of whom opined as
    to Terry’s mental health and one of whom interviewed multiple family members and
    opined that neglect, rather than abuse, was the central problem in Terry’s family. Counsel
    also put on extensive evidence of neglect in Terry’s childhood. The robust mitigation case
    presented by Terry’s lawyers is far removed from the performance criticized by our sister
    circuit in Abdul-Salaam. On this record, we decline to find that Terry’s counsel were
    deficient.
    36
    3.
    In any event, Terry suffered no prejudice from counsel’s alleged deficiency. “The
    question of whether counsel’s deficiency prejudiced the defense centers on whether there
    is a reasonable probability that, absent counsel’s errors, the sentencer would have
    concluded that the balance of aggravating and mitigating circumstances did not warrant
    death.” Sigmon, 956 F.3d at 192 (cleaned up). A showing of prejudice “requires a
    ‘substantial,’ not just ‘conceivable,’ likelihood of a different result.” Cullen v. Pinholster,
    
    563 U.S. 170
    , 189 (2011). To establish Strickland prejudice, Terry must demonstrate “a
    reasonable probability that at least one juror would have struck a different balance.”
    Wiggins, 
    539 U.S. at 537
    . In determining whether Terry has shown prejudice, we review
    the “totality of the evidence before the judge or jury.” Strickland, 
    466 U.S. at 695
    .
    Here, the jury heard substantial mitigating evidence—about both Terry’s neglectful
    and somewhat violent childhood and his significant brain damage. Four experts testified
    (without rebuttal from the state) to the effects of brain damage on Terry’s behavior,
    explaining in detail how Terry’s brain dysfunction limited his ability to control his behavior
    and how the various aggravating circumstances raised by the state were consistent with
    Terry’s mental impairment. Nevertheless, the jury took a little over an hour to recommend
    that Terry be sentenced to death.
    The reason, in our view, is because the aggravating circumstances of Terry’s crimes,
    and his propensity for violence, were too much to overcome. Before breaking into
    Jackson’s house and murdering her, Terry disconnected Jackson’s telephone so that she
    couldn’t call for help. He brutally beat Jackson, likely striking her with two weapons and
    37
    hitting her head multiple times with a blunt object hard enough to crush her skull. 13 See
    J.A. 372 (where Dr. Carter opined that Terry used two weapons during his assault on
    Jackson); State v. Terry, 529 S.E.2d at 276 (stating that Jackson’s “cause of death was blunt
    trauma with skull fracture and brain injury”). Terry also raped Jackson. This senseless
    murder was the culmination of a life littered with crimes and a pattern of violence,
    particularly toward women. In the face of the state’s case in aggravation, we agree with
    the district court that there’s no reasonable probability that Terry’s additional evidence of
    childhood abuse would have led even one juror to conclude that “the balance of aggravating
    and mitigating circumstances did not warrant death.” Sigmon, 956 F.3d at 192.
    The affidavits from Vogelsang and Schwartz-Watts concerning the effect of Terry’s
    childhood abuse on their analyses confirms our conclusion. Vogelsang doesn’t explain
    how the additional evidence of abuse would have changed her opinion, other than saying
    that the evidence “could have shed light on why Gary is the way he is.” J.A. 79. Dr.
    Schwartz-Watts explains that, had she known that Terry suffered childhood abuse, she
    would have opined that the abuse was “mitigating in its own right” and “is also significant
    with respect to significant brain dysfunction, as the abuse may have actually contributed to
    the dysfunction.” J.A. 102. Schwartz-Watts also states, “Terry had more neurological
    dysfunction than any patient I have ever evaluated, including those prior to 1997 and
    13
    The record doesn’t specify the type of weapon, or weapons, Terry used to beat
    and ultimately murder Jackson.
    38
    since.” Id. But she doesn’t connect this observation to Terry’s childhood abuse. 14 And
    as we have already explained, the evidence of abuse, though potentially mitigating in its
    own right, doesn’t overcome the mountain of aggravating evidence found in the record and
    is not prejudicial in light of the robust, and unrebutted, mitigation case Terry’s trial counsel
    did present. See, e.g., McHone v. Polk, 
    392 F.3d 691
    , 710 (4th Cir. 2004) (no prejudice
    from counsel’s failure to present evidence that as a child petitioner had witnessed his father
    “regularly inflict brutal beatings” on his mother and half-sister when counsel had presented
    evidence that petitioner’s father had engaged in “violent fights” with his mother).
    In sum, we’re not persuaded that Terry’s new mitigation theory would have fared
    any better than the case that was actually presented. Thus, even if counsel’s performance
    was deficient, it wasn’t prejudicial under Strickland and thus doesn’t excuse procedural
    default under Martinez.
    B.
    Terry next argues that counsel were deficient in jury selection for failing to ferret
    out jurors Brown and Ritchie who, Terry argues, were unqualified under Morgan. Once
    again, we disagree.
    “On habeas review, federal courts generally accord particular deference to the
    judgment of trial counsel during voir dire.” Gardner v. Ozmint, 
    511 F.3d 420
    , 426 (4th
    14
    Terry used Dr. Schwartz-Watts’s opinion regarding neurological dysfunction to
    support his argument to the district court that his counsel were deficient for failing to
    present a guilty but mentally ill defense. But he has abandoned that argument on appeal.
    39
    Cir. 2007) (cleaned up). Under Morgan, “[a] juror who will automatically vote for the
    death penalty in every case will fail in good faith to consider the evidence of aggravating
    and mitigating circumstances as the instructions require him to do.” 
    504 U.S. at 729
    . And
    “part of the guarantee of a defendant’s right to an impartial jury is an adequate voir dire to
    identify unqualified jurors.” 
    Id.
     Nonetheless, “[t]he Constitution . . . does not dictate a
    catechism for voir dire, but only that the defendant be afforded an impartial jury.” 
    Id.
    Terry fails to overcome the presumption that trial counsel rendered effective
    assistance in jury selection. See Strickland, 
    466 U.S. at 689
    . Counsel asked jurors Brown
    and Ritchie whether they could impose either a life or death sentence, even after convicting
    a defendant of murder and other crimes. Both said they could.
    Fifteen years later, after having heard all the evidence, and at variance with his
    answers during jury selection, Brown states that he “believe[s] the death penalty is the right
    punishment for murder if there are also other crimes.” J.A. 49. Ritchie is less categorical,
    saying that “the evidence regarding [Terry’s] brain injury did not impact me.” J.A. 51.
    These affidavits are of limited value to Terry, however, because “consideration of
    statements made by trial jurors after they experienced the entire trial and sentencing hearing
    and after deliberating on the verdicts are not reasonably probative of [the honesty of their
    answers to voir dire questions as to] whether [they] could consider the evidence with open
    minds and follow the court’s instructions on the law.” Neill v. Gibson, 
    278 F.3d 1044
    ,
    1056 (10th Cir. 2001) (cleaned up).
    And even if Brown and Ritchie weren’t qualified under Morgan, Terry doesn’t
    explain how counsel’s questions constituted deficient performance. Indeed, Terry doesn’t
    40
    suggest questions that trial counsel failed to ask to determine whether the jurors would
    have considered mitigating evidence after finding Terry guilty of murder, rape, and
    burglary. Nor does he explain what else counsel could have done to push back against the
    trial court’s limitations on the scope of their questions to prospective jurors.
    The district court correctly rejected this claim.
    C.
    Finally, the district court didn’t abuse its discretion by denying Terry an evidentiary
    hearing on his Strickland claims. To grant an evidentiary hearing, “there must be a viable
    constitutional claim, not a meritless one, and not simply a search for evidence that is
    supplemental to evidence already presented.” Segundo v. Davis, 
    831 F.3d 345
    , 351 (5th
    Cir. 2016) (cleaned up).
    Here, Terry has failed to present a viable constitutional claim of ineffective
    assistance of counsel, and the evidence of childhood abuse he now wishes us to consider
    is either supplemental to the evidence counsel presented at sentencing or was unavailable
    to trial counsel due to the errors of experts, for which counsel aren’t responsible. We
    therefore decline to order an evidentiary hearing.
    *      *       *
    For the reasons given, the judgment of the district court is
    AFFIRMED.
