And there's ABSOLUTELY nothing natural in resurrections. (Yes, I know in the comics happens everytime, but in a real world, it wouldn't). Besides, how about all the humans that mutants have killed in the past? If they can resurrect people and they have the law of "Kill no man", why can't they bring back all the humans they killed in the past? Like the X-Cutioner's family (the one from X-Men Gold), who were killed during one of Magneto's attacks? Tell him, "how is it fair for mutants to resurrect while innocent humans can't?".
In Marvel Universe, superhumans resurrect almost continuosly, but regular people don't. So how do you think they will allow Mutants to cheat death like that after they ruined so many innocent lives? And I'm basically talking about regular humans trapped in the crossfire between mutants.
