Sometimes Kieron Gillen reminds up all that he was raised Irish Catholic.
Oh my goodness are we about to see the rise of the Cult of Exodus because if so I'm all for it
Exodus is about to show the Nazarene Mutant how it’s really done.
Mystique/Siobhan is going to stab Shaw in the eye one of these days
She was resurrected whole and able to see.
Soon after her resurrection, her mutation triggered and she went through the whole cycle again of seeing visions and writing them down since the in(evitable) conclusion of the visions were that she would lose her physical eyesight.
Xavier doesn't trust his own decisions anymore. When push came to shove, he chose mankind over mutants (at least, that's how he sees it) and as a result, almost made them extinct (again).
Now paralysed with guilt and indecision, he's making good on the only thing that makes sense to him -- defending one of the few mutants left (the island), the home of all those he (thinks he) killed and prepared to die there.
It's depression. Pure and simple.
Nothing will move him from that rock except maybe the return of Magneto (Max, not Joseph) or seeing the mutants alive and well again. Simply hearing that they're OK and fine won't be enough as proven from the Emma mental conversation. He won't accept that that's true and not others trying to get him out of the funk.
Unclear, but I strongly believe the answer to your question will ultimately be a resounding YES. I think the 250k mutants are in that lantern of hers from X-amen 25.
I’ll take it a step further. I think that Mama was Right(teous) has achieved DOMINION. The key is in that desert scene where the caption says “Noplace, Nowhen). I think the mutants are outside time and space, the very definition of dominion, with Big Mama. And that’s why Xavier can’t find them. They’re outside time and space in dominion minion with Essex’ sweetheart.

You gotta start somewhere. And this is accurate considering his history.
It's not very noble or likeable or whatever but this is pretty consistent.
Someone asked about Apoc's return waking Chuck up... yes and no, the big A will return and monologue disappointingly at Prof but that isn't gonna get him to shake it off.
Finally, ol' Blue Lips will tire of it and then kick some butt up down and all across the island. That'll start him on the road to recovery. Kicking and screaming, yes, but it is what works.
This type of personality usually will not "snap out of it" on their own. They need other agents to move them along. They'll too happy wallowing in their own misery.
