So example, Joker and twoface have territorial disputes and gang violence. But occasionally twoface will try to interfere with Joker's plans for simply being too evil, while incoherently doing something just as evil somewhere else.

Batman can choose to support twoface being the lesser of two evils at times, or reject his overall instability and unreliability. Maybe twoface even abides by Batman's "no killing" rule, requesting Batman's help to use non-lethal means, and at other times just committing mass murder, making him a character that you really can't trust but occasionally have to work with. He would be a good metaphor for a corrupt government official.

Twoface is really the spawn of Joker, who just wants chaos. Make him good half the time, not just "another mobster".
