KoS will always be part of the game, it's just something you have to accept. Running in a group makes this less of a problem sure (OR at least avenges your death) but you have to accept it. I've had this happen a few times to me, and I'm only angry about 2 of those occasions. 1 Was a guy being attacked by zombies (Was in a city). I'd heard and saw him down one with a gunshot, but as he then put his gun away and drew his axe, I assumed (Wrongly) he was out of ammo. So I stepped in ( Not even geared well, only weapon I had was a baseball bat) And helped deal with the group. I then proceeded to back away, putting away said bat, only to see him draw his gun and shoot me. The second time was an unarmed player, who upon seeing me, raised his fists and ran at me, to which I drew a shovel (Only weapon at the time). He stopped, and I backed off, moved on a little bit. A few moments later, I see said player again, with a friend carrying a gun. I raised my hands only to be shot. Now probably the guy wanted my shovel ( Good luck with it, was the only weapon I had found and was badly damaged), but still, this annoyed me. There have been other occasions when I've been shot and I laugh about due to my own fault. Like seeing what I thought was a zombie in front of the building I wanted to go in, so I ran at it Axe raised. Only at the last moment did I realise it was a person with a gun. Who put me down. So like I said, unless it really pisses you off for a reasonable reason, just laugh it off, respawn, gear up and have fun in this apocalypse =)
