And he sees Hank who works for the CIA while getting looked down by them and does his best to please his bosses as a kind of awful mirror of the past.

One interesting difference between comicverse Erik and the movie version is that comicverse has an older sister, while movie Erik is an only child as far as we know. Not that only children are automatically selfish - in fact, I've found that having all family responsibility stacked on them often leads to the exact opposite. But given his apparent lack of any really intimate relationships between his childhood and meeting Raven and Charles, he might well never have been close to anyone that he had to share with someone else.
