In other instances, Xavier is shown to be secretive and manipulative. During the Onslaught storyline, the X-Men find Xavier's files, the "Xavier Protocols", which detail how to kill many of the characters, including Xavier himself, should the need ever arise, such as if they went rogue. Astonishing X-Men vol. 3, #12 (August 2005) reveals that when Xavier realizes that the Danger Room has become sentient, he keeps it trapped and experiments on it for years, an act that Cyclops calls "the oppression of a new life" and equates to humanity's treatment of mutants (however, X-Men Legacy #220 - 224 reveals that Xavier did not intend for the Danger Room to become sentient: it was an accident, and Xavier sought a way to free Danger, but was unable to find a way to accomplish this without deleting her sentience as well).
