She made a decision.
X-Men: First Class, you know that MacTaggert and Xavier were quite close, but Xavier erased her memories of everything that had happened, including that the two of them had met. MacTaggert goes on to get married to someone else and has a son; then, in favor of her career, she divorces, the "choice we all have to make." The truth is, she had all ready made a decision: to get married. She choose marriage and family, then went back on her decision when she choose her career over her husband. THIS is what unleashes Apocalypse, feminists who choose their careers over their families and marginalize the men who are supposed to be the husbands and fathers. Just as Apocalypse isn't a man, he's man-like, so, too, are men today only "man-like" because women have taken away their ability to be truly masculine in their decisions to raise children alone and not be married. So, what feminists have claimed men have done unto them for centuries, feminists are now trying to do to men. REMEMBER: it's not the war-like worshipers of Apocalypse who release him, it's Moira. Which leads us to why Xavier was wrong to erase Moira's memories.
X-Men: The Last Stand. Again, we all have choices to make, there is good and bad in each of us and we have to decide which of those powers we are going to strengthen with our free will.
