I think that the KOS part of dayz is a unique game feature. What do I mean by that? Well there are several things (and I will try to explain them), and it gets more interesting with the more features they add. Now the people that do not KoS but instead restrain someone, take what they need and let them go with enough supplies to live on are sort of like the ricks of the world. They want to get what they need to better the odds of their survival and the survival of their friends with minimal damage to others. But they take a huge risk trying to detain people and then letting them go. What if that person is part of a larger group? What if they return with more men and more firepower? Sure they probably won't stick around to find out. But there is also no gaurantee that they won't stalk you and alert their friends of your position (paranoia). So this sort of paranoia spurs people, and I would say most people, to not trust other people. There is simply too much to loose and not enough to gain, and so these type of players (which I would say would be most people) either avoid human contact with strangers to stay safe, or they kill strangers on sight as a means of survival like the governor. One way is not above the other. It's just a unique part of human nature woven into a game like I have never seen before. I think once we are able to build bases it will provoke more human interactions that don't end in death. It will also provoke wars between neighboring communities like we saw in the walking dead, and that is what makes this game so great. The fact that people will kos makes trying to detain them and take blood from them so much harder,,you can just tell a geared up player to freeze unless you really know how to do it and get away with it. You have to stalk people for miles sometimes just to make sure their alone and then go in for the steal or kill. Dayz would not be as adrenaline pumping without the majority of people killing on site. All that being said there are still trolls out there who kill noobs for fun and they gain little from it. No loot. No chase. Nothing.
