Sociopathic Hero/Sandbox

"The streets are extended gutters and the gutters are full of blood and when the drains finally scab over, all the vermin will drown. The accumulated filth of all their sex and murder will foam up about their waists and all the whores and politicians will look up and shout "Save us!"... and I'll look down and whisper "No.""

- Rorschach, Watchmen

They fight for the good guys. They might even believe in the cause. But they are a hero only in name.

They solve every problem in much the same way as a villain would--ruthlessly manipulating and killing their way to their goal. They routinely torture, murder, and commit evil acts nearly as bad as the Big Bad. They'll do whatever it takes to win. The people they fight beside worry about their behavior, but feel "At least they're on our side."
