Actually, just the other day I stopped and went back to kill a rabbit that was hurt. It had been hit and it's back legs were useless and it was pulling it self by its front legs. I didn't have a weapon, so I just stepped on its head. If I can go back and finish it, I will, just sometimes it's not safe to do so, like on an interstate or whatever.

To let a deer or anything else suffer just because it hurt your car, thats down right cruelty. It wasn't it's fault it was trying to cross the road to get something to eat. What if I accidentally hit you with my car and your legs and arms are broke, and you can't move. Can I just leave you there to die? Even though it may take a few days all the while your in excruciating pain?
