Elite

One of the most interesting parts of the second season of Daredevil was when Frank Castle and Matt Murdock defended their own views on what justice is. This dialogue could be continued in the Punisher show, if the Elite is brought in.

Basically, Elite is a vigilante, just like Frank Castle. However, unlike him, Elite punishes everybody, even if the offense is something as innocent as letting your dog urinate on the sidewalk. In a way, this villain is a Punisher taken to the extreme.

This would also see Frank Castle basically reiterating other monologues from the Daredevil show, particularly the ones about the heroes creating vigilantes. Would the Punisher change his perspective on what justice is? Or will he react, just like in the comics, killing Elite?

And this opens other possibilities, as well, since Elite needn’t and shouldn’t be the main antagonist. He could be part of a side-story, one that would make The Punisher even more interesting.
