Sequels The Actors for X4.

[ntcrawler]

The Movies have it at she was NOT herself & a completely different Personality. Sure if she came back she would have to live with what she did but it was not HER HER

Plus look at who her victims were:

1. Scott, who most likely isn't dead after all
2. Prof X, who tried the equivalent of a mind-rape and ticked her off (but survived)
3. Soldiers who attacked her from behind (without being provoked by any actions she took)
3. Mutants fighting on Magneto's side who already killed or hurt other people.

So when you look at her track record, not so bad. certainly not even close to devouring a star and destroying 5 billion people
