What is the test for a jury to return a sentence of death for a convicted rapist?

As in People v. Milner (1988) 45 Cal.3d 227, 257, 246 Cal.Rptr. 713, 753 P.2d 669, we conclude that the jury in this case may well have been persuaded to adopt the view that its responsibility was merely to weigh aggravating and mitigating factors without regard to the appropriateness of [47 Cal.3d 1041] the alternative penalties and that it was required to return a sentence of death if aggravating factors preponderated without each juror making a personal conclusion from the evidence that death was appropriate under the circumstances for the offense and the offender.
