Argument: Death penalty can/should inflict pain on murderers; due desert
Bob Greene. "Who Weeps for the Blood of the Weiler Family?". Chicago Tribune. 14 July 1999 - "When Allen Lee Davis got a nosebleed during his execution, it caused an uproar. Few of those crying foul even knew what he had done to deserve execution." Some go beyond this, arguing that causing pain to the executed is justified as a proportional (due desert) response to the heinous crimes they've committed.
