So while you can expect The Batman’s Two-Face to be a crime boss, it could be intriguing for the movie to present a scenario where thanks to pure chance, the scarred Harvey Dent ends up having to help Batman.
The thing that separates Two-Face from most other Batman villains is that because he relies on his coin for making all important decisions, depending on what side it lands on, he has the capacity to do good, or at least make a decision that benefits Batman or another good guy rather than his own self interest.
