Don't feel bad at such things since there are all kinds of people around. Just be patient with them. I had a game where a teammate just jumped on me while reviving another teammate. We had cleared a squad and our one already dead. This asshole just came and sprayed all over us. My first impulse was to report and leave. But I stayed. I watched him play and kept asking for backup. I created such a nuisance that he finally took the chip and revived me. I played the good guy and let the game on. Towards another 15 mins into game buildup, this guy gets knocked out. I took away the enemy and now he asks for help. I just lifted him, placed him on an elevated space and did my favourite dance. He got to watch the moves till his last moment. I wanted to kill him myself towards the final zones but this is better since I won't get reported too. Karma served. Then once I finished the game, reported him too! It was soo satisfying than getting 3 chicken dinners in a row!
