This is one of the most basic feelings a person could have, and maybe one that's a little awkward, but I'm getting old, and I just had the thought that people who hurt each other is a very sad subject.
Video game wise, since it seems that many people feel the same way, it's notions like this that made games like Undertale very popular. The idea that mindless killing carries reprecussions, and results in rather sad outcomes for the affected parties. That's just video games though.
People like to argue about "SJWs", but if there are people "among them" who are fighting for peace, more power to them. I realize that means losing some of the things I love most, and that's a large reason I feel opposed. It's sadly one of the most logical side effects of a world that would promote sublime peace.
Take care of the people you love while you still have them.
