Counterexample: most Buddhists.

Your enemies (and, you know, the rest of humanity) are not innately evil: there are very few people who will willingly torture people. There are quite a lot of people who will torture horrible mockeries of humanity / the Enemy, and an awful lot of people who will torture people because someone in authority told them to, but very few people who feel comfortable with torturing things they consider people. The Chinese governement does some pretty vile things; I nevertheless doubt that every Party bureaucrat would be happy to be involved in them.
