I am new to the game with no prior experience with the mod, so maybe I can offer some insight from an outsider's perspective. In my short experience, I would say that 20-30% of people I come across will kill me on sight. While I consider that statistic high, I don't consider it high enough for me to kill everyone I see. As of now, I have only ever killed one person on sight, and I considered them to be a real threat. I walked into one of the buildings at an air strip and found a guy with an M4 drawn looting with his back turned to me. I was fairly sure I would die if he turned around and saw me so close so I blasted him. Besides that one incident, I always attempt to talk to or avoid everyone I come across, depending on their proximity to me. I realize that KoS is probably a safe bet for any one person and if all I was interested in was keeping my own ass alive then that's what I would be doing. One thing holds me back though; wouldn't it get boring shooting everyone you see after a while? For every ornery asshole I come across, I also meet one good one. I usually offer supplies to anyone I come across and sometimes team up with random people to loot some of the more dangerous places like airfields. To me, the prospect of potential partnership outweighs the risk of being shot on sight. I have been playing online games long enough to realize that some of the best times and friendships to be had are with random strangers at chance encounters. I feel sorry for those who make a habbit out of KoS because they will not have many of those experiences. By the way, I am not against PvP in this game or any other. In fact, it's one of my favorite things. I just believe that there is a time and a place for it and I would hate for myself or anyone I come across to lose their hours of adventure just so some sociopath could sate their bloodlust for a few seconds. They make other games designed specifically for that.
