John seems to have developed a God complex or sth. I don't know the original story so I am not sure if there is something he can do to help. But he is just being a spectator here, coldly watching the situations unfold and seems like he is enjoying seeing the troubled avengers and mutants.
I understand what you mean, but he has no obligation to help all Universes, even because Universes are "infinite" (sometimes they say infinite, other stories don't, I at least think it should be infinite, since it has infinite possibilities) would he spend the rest of his life helping the universes, without having a life? and also the story is not over, after "no more mutants" there are still other continuation stories, such as the civil war.
