Don't feel guilty about it. I recentry killed a guy with the name Jack outside of elektro. Not because to get his loot but because of plain panic. He had a Pistol and a m4. It feels like he would have shot me, but you never know. I also felt guilty because I spared a guy spawning in the same barn as me. I could have shot him. Luckily he moved behind some hay and stated he was friendly. Anyway, I spared him and he didn't shoot me neither did I. And like most posts here suggest. I would have done the same thing.
