12The Punisher (Frank Castle) will pose a moral as well as a physical challenge to Daredevil (Matt Murdock).
This one is a virtual certainty given that the Punisher is a major force in season 2. It’s an externalization of the inner conflict in season 1. There, Matt struggled mightily with the ethical question of whether to kill an evil man, the Kingpin. Now that he at least
thinks he’s made up his mind to be merciful, in will come the Punisher, who is all about killing evil people as quickly and efficiently as possible.
Even if the simplicity of Castle’s methods doesn’t tempt Matt at all, it will still force him to define the exact difference between himself and someone like Frank. That’s what gives their relationship meaning in the comics, too.
