In a Death Penalty Case, Jurors Sitting on the Penalty

In a death penalty case, jurors sitting on the penalty phase

A) are not the usually same as the jurors sitting on the guilt-determining phase
B) also have to find by a simple majority that in addition to convicting the defendant of the crime, "aggravating" factors were proven
C) also have to make a reasoned moral response in the case to determine if mitigating factors were sufficiently present to allow the juror to find that the death penalty was not morally appropriate in the case
D) don't have to struggle with the judge's instructions because research has shown that most jurors understand the instructions very well
