Found some random guy NW of elektro, and gave him a spare gun I had on me. I asked him if he wanted to go to cherno for supplies and we ran off together. We made it to the lonely house east of Prigorodky when 2 others shot at us from the trees. We ran for the wall but he gets shot, losses his legs, and cries out for me to help him. He gets shot in the head while I'm safe and scared behind a wall which i eventually run towards the coast from. I felt bad for 3 days after feeling like I could have done something. I still think about it at least once a week even after a few months of it happening
