You've got to be kidding.

Not at all he's a bit of a shit all the way through the saga.

If the story is about him redeeming himself he has a lot to do as ghost to achieve that, I can't really seeing him as falling either, he spent most of the PT acting just the same as he did as Vader (only without the cool costume and the dignified voice).

If you asking me if I want to sit through three more films with Hayden in, clearly no I don't.

The two we already have are bad enough.

Jumping into a future where Seb Shaw's ghost has been trying to guide Luke and Leia to a point the damage caused by their father is fixed would work.

Not that it's ever going to happen.

Besides most of the problems in the Star Wars galaxy were not caused by Vader or Palpatine (they just exploited the mess that was already there).
