It is a very good question.
i think humanity is in need for new heroes, that will

Super-villans are what make super-heroes. We need to acknowledge that this is the age of super-villans. Ledger set the pace for the face of the super-villan like Jackson set the pace for book to movie.
We will be seeing a new breed of super-villans in the future with super-heroes barely coming out above them.
