love the idea. i think it would be great to come across a survivors body and see that he had a large number of bandanas (bandit kills) but say a low amount of human teeth (survivor kills/'murders'), showing that he had been hunting bandits :D or killing a bandit yourself and seeing that he had a lot of murders. Then also if you killed a guy and when you checked they had very little zombie/bandit/murder kills (low teeth and bandanna numbers) you would feel bad for killing a 'newborn' player. I think in the leaderboards you should be able to see how many of YOUR OWN teeth have been taken in game i.e how many times you've been murdered. This would add so much +1
