What Professor X Thinks About Every Major X-Men Member
3. Jean Grey
Jean Grey is a lovely young woman who has also destroyed potential billions of lives after she sort of destroyed that planet that one time, raising the question of why nobody ever gave her the superhero name of "the human juxtaposition".
Possibly because semi-permanently bonded to an entity that is just a bastion of destruction, and nobody wants to risk getting burned. Literally burned, of course - the Phoenix does not mess around.
Also let's forget about that time I was in love with her. Let's put that with the other questionable plot lines of the past: far, far, faaaar away from our current reality.
