I just started reading Xmen. I am reading from the start. I am enjoying the stories. But one thing troubles me. Professor X has used his powers twice in as many issues to erase the memory of several people. First on The Vanisher, the again on The Blob and his gang. He is always going on in the comics and shows I have seen him in about the dangers of misusing mutant powers. Does having him erasing the minds of his foes Ethical or is it crossing the line?
