really he hasnt, at least not since Schism. Heck the efforts to gradually stop writing him as dark and shady started back after Second Coming. As for Children's Crusade, I cant say he was wrong. Scarlet Witch DID end up killing tons of mutants with her actions. Crazy or not, people suffered and what she did amounts to genocide. You say he's been spiraling since MC, but he is the way he is bc of SW. M-day, formation of Utopia, X-force, becoming the unofficial mutant ambassador ALL tie back to what she did. People want her dead and for good reason. Considering the position he is in, I dont think he can stand by and not do anything about her. Those ex-mutants want justice and they are looking at him to seek it. I think he was justified in wanting to take her back with the X-men and I think he'd lock her up in the X-Brig while they assess the situation. If someone were to wipe out hundreds of people of a particular race, wouldnt people be calling for death penalty of that person or at least a life sentence? To me, its no different
