Many Roles = Judge, Jury, Jury Executioner

If Harvey starts off as Gotham’s symbol of hope after the flood but slowly falls after realizing the system protects its own corruption, at that point he stops believing in the system entirely and basically becomes Gotham’s “judge, jury, and executioner”. The distinct split personality of Two-Face. That’s why I think “many roles” fits Harvey perfectly. I don’t think this character needs to be mixed with another like Hush.

So if Part I showed Riddler exposing the corrupt system and Part II shows the corrupt system protecting itself like destroying Harvey, Part III could be about overthrowing the corrupt system. With the main rogues. Borrowing from TLH which had Two-Face causing the Arkham breakout. This also lines up with Harvey Dent/Two-Face because if the system falls him, he could become someone wanting to act as the system of justice alone, becoming his own “judge, jury, executioner”.
