Michael is like what Castiel was?

I'm pretty sure they're very different. Michael's whole life lost is meaning, like Blaziken said, billions upon billions of years' work turning out to be a waste, a failure. He was abandoned, trapped in a Cage, with no hope of escaping, and no reason to think he ever would. In short, Michael's condition is far worse, and runs far more deeper.

Castiel? He was suffering from past regrets, yes, but he also had things to keep him going, friends to be happy for, the ability to move around. The amount of damage and guilt and pain is on a whole different scale for Michael. Really.

I'm also fairly sure God could have fixed Castiel back then, even if a small bit. I have no idea what could save Michael, besides being brainwashed.
