Why are you people so obsessed with antagonists? Their mere presence has caused no small amount of discussion, which I think that benefits no one's entertainment.

This is just my player opinion, but why not try to do more characters that won't try to tear the game apart by merely existing? Especially when there's no feasible way for heroic PCs to deal with antagonists without removing people's characters from the RP, which is not a fun thing to do.
