I think he is just a fanatic and annoying jerk. Also, we never saw him commit any crimes.

Other than you know, kill that guy on the glass bridge. And stall putting everyone in danger of dying. And suggest attacking and killing other teams. He does enough to qualify.

I recall that the guy on the glass bridge fell during a struggle between the two of them, he wasn't pushed intentionally. And putting everyone in danger does not necessarily mean to be evil, I think he was just being a jerk and stupid at that point. Then suggesting something more radical like he did might be an indicative, but he never really did anything.
