...I'm not really close to him or anything, but I'm not going to leave someone alone who needs help being defended against someone who's trying to kill them. It's kind of complicated since half the people on the community seem like they either kill people regularly or want to kill people, then there's probably some who have killed people and aren't open about it. I can't just go around screaming at everyone who kills or has killed someone, it's not my business to judge that kind of thing. There's no way I could let it happen if I'm right there, but that goes for anyone so it doesn't really have to do much with it being Greed there unless you have a real reason that he should die. Not just whatever stupid fight you two had, which I'm probably guessing has to do with him being an asshole and you actually getting upset about it like it was some kind of secret.
