User blog comment:Gekkou30/Who is Crazier The Joker or Deadpool?/@comment-5388187-20130309005527

Joker is insane. Deadpool isn't so bad. He doesn't kill innocents for fun and he's been on several super-hero teams. I'd go as far as to say he is simply eccentric.

If you read X-Force, you'll see he isn't as crazy as you'd expect and is actually capable of forming bonds with other human beings (Or whatever you'd consider Genesis to be...).
