I don't think animals can have sin, since they didn't eat the fruit of knowledge, and are all pre-programed with instincts. Just to clarify with my belief...

Anyways, I have to agree with D3V(and K_A's, lol)'s last post. At the same time, everyone should have the choice to make up for what they've done - as they might truely regret it. Remember that bald guy who was getting death penalty? I dunno, he just suddenly came to mind.
