Can the Texas death penalty statute be reconciled with this Court's long-established mitigation jurisprudence?

Question Presented is: Can the Texas death penalty statute, which instructs the jury to consider “the circumstances of the offense, the defendant’s character and background, and the personal moral culpability of the defendant,” but then limits the scope of the evidence that jurors consider mitigating to “evidence that a juror might regard as reducing the defendant’s moral blameworthiness,” be reconciled with this Court’s long-established mitigation jurisprudence? i
