You must not forget that in DayZ you can get the most valuable loot by killing another player. The game-mechanics encourage you to kill, because you can get food, ammo and other tools so much faster by shooting other players. It takes a long time and some luck if you try to get it by raiding small villages - which is what I do, because I play it as a survival-sim, not a PvP-game. I avoid all form of human contact, I don't shoot at people who don't shoot at me but I will try to get away as quickly and safely as possible, no matter how nice the other guy seems to be. Takes more time to survive and I will get less cool stuff, but hey, I don't die. I haven't died once since I started with the game, 4 days ago.
