The biggest problem with that for me, was his role as Captain Commander. If he's in charge of protecting Krakoa and his family, shouldn't he be focused on what's trying to kill them?
It's even odder to me when he states otherwise to Jean in X-Men #15, and he emphasizes the need to fight and protect what they have. He makes a great speech in front of the council, but he comes off as too reactive. Honestly, everyone comes off as too reactive.
With most of his family gone or preoccupied, he doesn't seem to have changed either. So, if that was his main catalyst for his current change, what happened? Havok and Cable seem to have had no effect. It's all just odd for me.
