It's just this idea I had for an RP a while back, with a friend of mine who played an excellent Deathstroke.

Don't ask me how, but he was going to wind up on her therapy couch. She isn't human, so she has different ideas about people who kill people.

Also, I don't think Slade's about chaos. Yes, he messes with people, but I have a sense that he's doing everything for a reason. Problem is that no one else knows the reasons but him.
