I mean, how epically dumb do you have to be to make your plea for the survival of hundreds of sailors be "they're just following orders" when you are talking to a Holocaust survivor? Pretty much the 1st thing that came out of my mouth when the movie was over. I agree with everything you've said here. I've always tended to agree more with Magneto than Prof. X anyway but this movie just cemented it.

Also that while Charles can access other's memories and have sympathy for them, he doesn't have true empathy. I don't know if the idea was to have him come off as a privileged, naive, kind of douchy character--with the idea that he grows into the Prof X persona and Erik as a bad ass vigilante antihero character (who lets just say if he's auditioning for James Bond--totally pulled it off)who grows into a meglomaniac but that's how it came off.
