Warning 1: Worm is really, really, really long.

Warning 2: Although indeed a character in the story faces this issue, I don't recall anything particularly surprising or insightful about it in the story. Which, for the avoidance of doubt, I don't regard as a defect: the purpose of Worm is to tell a particular story the author wanted to tell, not to conduct a careful philosophical investigation into the civic responsibilities of superheroes.

(Worm does have a thing or two to say about the civic responsibilities of superheroes, I guess, but most of it isn't said specifically through that subplot. After all, pretty much all its characters are superheroes/supervillains.)
