All fair points. Just because an idea makes some sense, doesn't mean it's going to be well done.
Scott's reacting to how bad things are and taking personal responsibility for it (like always). I think we often forget how often Jean, Charles or Ororo would be around to tell Scott something he was obsessing about wasn't his fault. Logan's already filling that role in the Uncanny 12 preview, not perhaps like Jean would have done it, but about the most affirmation Scott's going to get from Logan.
I don't think he blames Jean or Ororo or Kitty for what's going on. He blames himself. That's the lead-in Marvel is using to drive the whole "I have to go back to being like before, I ruined everything" angle as you said.
