So, murder > murder? What if there was justification for killing a puppy? Your justification for a human would be that this person is a nuisance to society. He has killed before, and will kill again. Could you use that justification to kill a puppy? What if a young pitbull was playing to rough with a child that wasn't being supervised? He has tasted blood, and has killed before and will kill again. Therfore, we should kill the puppy.

Your both r'tard's.
