I GM a lot which means I often play the antagonist so I guess I exhibit a lot of, what I believe to be, negative traits in my characters. By this I mean I will have them express beliefs and take actions that I think are bad or worng because it gives the RPers something to defeat that I want to see defeated. That’s just for storytelling reasons though as having a villain that isn’t villainous is kind silly really. I don't really think anyone reads that deeply into RPs and I find the thought that someone could form opinions of society based on RPs terrifying.
