Circle of Blood

Circle of Blood is just the beginning of a bigger Punisher story arc, in which the anti-hero is pitted against an organization he himself believed to be good. It is also the story in which the character's most definitive traits are outlined, including his code of honor.

Basically, Punisher is sprung out of prison by an organization called the Trust, which is actively fighting crime. It isn't so, though. And this does resemble what happened in the second season of Daredevil "“ however, Frank knew that he was released by a villain. And he says that the next time they meet he won't be so forgiving.

At this moment, it is safe to say that Kingpin is the best villain in the MCU (Loki is more of an anti-hero, while the most recent reviews say that Zemo is another miss for Marvel). So Circle of Blood could be about the Kingpin still manipulating Frank into killing his competition. And when Frank finally finds out, there will be blood.
