>>104752067>So what is Two Faces MO?Duality, games of chance, and breaking the law.
>Why does he decide to be a mobster.Because in his mind that's the opposite of Harvey Dent, District Attorney of Gotham City.
>To what end does being a criminal give him?Satisfies his neuroses.
>Unlike Penguin who is able to live a normal comfortable life outside his life of crime that doesn't seem to be Harvey's case.Harvey was incapable of a normal comfortable life with or without crime. That's why he snapped and became Two Face.
OP I feel like the problem you're having is you're attempting to apply logic to someone that is, medically speaking, a batshit crazy lunatic. Two Face is a criminal mastermind because Harvey Dent fought for justice. Where Harvey Dent was Law and Order, Two face is Crime and Chaos. The benefit he gets from a successful heist or murder is that he can keep stealing and killing because in his sick mind, that's what makes him who he is.
Dent spent his whole life running away from being Big Bad Harv and now he's done running. And now Gotham will run from him.
