It's true there has been fantastic characters and plots along Batman's story, I'm not gonna deny it, but, in the base, they're dispensable in the path of Bruce Wayne.
I don't know if he qualifies as a psychopath, but Superman's arch nemesis is a powerless human: Lex Luthor.
And even Batman's human rogues are pretty surreal and unusual, such as Two-Face with his perfectly divided face, the Joker with his clown-like features from falling in chemicals and evergreen hair. The primary interpretations depict these "scars" as too perfect and flawless and it's only ever intentionally-realistic reinterpretations that make Two-Face's "faces" not so perfectly divided or the Joker's face not so white or his hair not so green.
