Well, you sure are paranoid :D But I don't blame you, I myself am very cautious with other players aswell. One day I was sitting in the cherno firestation when suddenly I heard and saw gunshots barely missing me. I looked around and almost immediately found the shooter, sitting a level on top of me. I took no chance and emptied my M16 mag in him. Looking afterwards, I doubted why I shot him...He missed all his shots (he had a Winchester 1866) and had pretty much nothing else on him. What if he was trying to draw my attention in a very, very wrong way? By thinking about this I thought I was kinda paranoid aswell :D Then, when I made my way down the firestation I noticed a green chemlight running towards me, hunted by about a million zeds. When he was inside I KOS him without hesitation. Poor fella was probably looking for shelter. He did have a nice gun (L85 :P) but without any ammo. Again, he probably wasn't going to shoot me and again, I was convinced of my own paranoia once again. But, a couple of days ago, I was looting a camp when 2 guys showed up about 100m away from it (they didn't know there was a camp). I was alone, so shooting them was probably the worst thing to do as they already noticed me. They came to me but didn't say anything (my pulse was about 200 bpm :P) and just looked around a bit in my backpack and they left. Since then, my paranoia faded away, though I'm still very cautious with other survivors. There still are some non-violent souls out there, you just gotta find them! :D
