I mean... the Punisher is explicitly a terrorist, and every time he comes into contact with any other hero it's driven in with a farking sledgehammer that he's the bad guy.  He basically exists only to serve as an example of "doing it wrong" so that other characters can be distinguished as being more genuinely heroic in their methods.

For bonus points, while in his own title he's always 100% righteous from his own point of view, basically any time some other perspective is introduced Castle is shown to be factually wrong, as in he is straight-up murdering people who are explicitly innocent of the things he thinks they're getting away with (well, "attempting to" murder, the other heroes always stop him and he learns a valuable lesson that day because Marvel... then goes right back to the old behavior after "learning" that lesson until it's time to learn it again next crossover).  Kinda unsubtle, the implications on that one.

Basically I'd say that the use of the logo is accidentally more appropriate than the terrorists using it intended it to be, since the message it actually sends happens to be more what they're actually about than what they think it means.
