[Batman Beyond] What were the fates of the rest of Batman's villains?

We know about Joker, Ra's al Ghul, Mr. Freeze, and Bane. Whatever happened to the rest of them? How many actually reformed or were cured? Did any die during one of their schemes? (By accident or by another criminal, or even GCPD, of course.)

Harley evidently survived Joker and doing a not so great job of trying to divert Dee & Dee from flowing her footsteps. 

I don't like to count the Post Infinite Crisis DC comics as part of the DCAU continuity but if you wanted to, they also showed some other characters fates.
