I feel the need to point out Iron Man has killed before when he felt their was no other option.

Also point out that Batman does not kill and he has more than his fair share of the DC villains. It is very difficult to deal with a psychopath when you can not kill them but at least in a comic book universe it's still possible.

I also have to agree with Jet Marvel has some truly evil villains as well. While not great for the content try reading Maximum Carnage where a group of psychotic super villains with super powers break out. Personality wise they would belong right in Arkham yet I have no doubt if their was a fight between that group and the inmates at Arkham Carnage's group would come out on top.
