I have no idea what said storyline is about (my comics knowledge is nearly nil), but I would pay good money to see Charles' chickens come home to roost. I would even shell out for movie theater popcorn to go with it.

I don't think that Charles at the end of the film has yet reached a truly adult ethics of telepathy.

Definitely not. One can only hope that the fact that all the people he cared about left him will provide a massive cluebat for him.
