Xavier also repeatedly tampers with other people's minds to reach his goals, but he recognizes his flaws. In one instance, Xavier finds that Iceman has told a girl several secrets about the X-Men and is forced to erase the conversation from their minds. He generally believes that reading minds without permission is unacceptable, or so he leads his students to believe. In "Ultimate X-Men" #40, when Angel flies away, the Professor sends Storm after him because he telepathically knows that Angel is attracted to her. Similarly, Beast questions whether Xavier has made Storm love him.
