When I think with my head, I am against the death penalty for a few reasons.
When I read the article linked above, my gut reaction is to think 'hand me the shotgun, I'll do it myself'.
But the real question is: should justice be determined by our gut reaction, or by logical reason?
(Not being goady, sometimes I am not so sure of the answer to that!)
Both the dogs and the monkeys are deeply distressing examples of the utter depravity some people are capable of. I don't doubt the world would be better off without them.
