So Wanda decimates the entire mutant population. Warps reality. Murders millions. And she gets to be an Avenger Again after saying sorry.
Scott Summers goes mad with the Phoenix Power (and it wasn't his fault he got it *cough Tony Stark cough*), builds a totalitarian utopia for mutants and he's a wanted criminal.
Is that fair? Shouldn't Scott be given a chance to redeem himself like Wanda. And if you ask me, Wanda did more harm than Scott did.
