he's made up for the damage he's done. though he is paying societies punishment for murder, he should not in my opinion be put to death. no one knows that after taking 4 lives how many hundreds more he most likely saved from entering the same lifestyle that he himself was a creator of.

death penalty shouldnt be exercised in his case, but he shouldnt be set free. and if he is given a break, a MIN-SEC prison would be the best option.
