Every death sentence involves first an eligibility determination and then a selection of an eligible defendant for the death penalty. A defendant is eligible for the death penalty once the jury has concluded that he is a member of that narrow class of criminal defendants who have committed the most morally outrageous of crimes. An eligible defendant is then selected for the death penalty after the sentencer takes into account mitigating evidence about the character and record of the defendant in order to decide whether that individual is worthy of a death sentence.
