I think humanity should remain in the game and like every other aspect it is a work in progress. I believe there is a lot of potential of how humanity could manifest itself in game beyond the current skin change system. After all, the very concept of humanity in a zombie apocalypse is a "resource". How do we define ourselves as humans in such a grim situation? To go around murdering people you know as "innocent" with zero consequence is the antithesis of realism. Let's not forget this is a simulation, a very good one, but not reality. When you fire a gun in game, your hand doesn't shake on the mouse, your ears don't ring. The game animates recoil and plays a sound through your speakers to best approximate the experience of shooting a real gun. So by participating in any game with guns, no matter how realistic, you are conceding that you are willing to accept an approximation and not actual reality. With all simulations the game is doing it's best to represent real life phenomena. That said, when it comes to killing people, If you ran around murdering innocent humans in a zed world, you can be assured your psyche would be greatly altered as well as the way others perceive you. Conveying this in game with a skin change is certainly not the ultimate representation of the complexities of humanity, but it acknowledges it exists. I think this is an important game mechanic, if not the most important game mechanic in Day Z. It deserves the same attention and development as all the other game mechanics and would be a terrible disservice to remove it because a few hyperbolic shouts of anti-realism or that those intrigued by the system are inherently cowards. As a theoretical zed apocalypse persists, humanity will be the most precious and rare resource of all. Imagine Day Z down the road, maybe we will all have bandit skins because the world is so cruel and unforgiving, no matter your moral intentions when you first started playing. A bandit skin could come to represent how long you have lived. "I remember when I was innocent like you, wet behind the ears. Pious, on a soap box murmuring about humanity and what it means to be good. But you'll change. You'll change or you'll die. Welcome to Chernaus"
