the whole reason I want him back is because I feel he genuinely deserves another shot at this role.

Yes, by all means, a decision to hugely affect the Sequel Trilogy's themes, plot, and character should be made based solely on giving an actor a chance to redeem himself.

Friends, try for a moment to envision the inevitable scene that will take place (if this rumor is true) involving a spectral Hayden Christensen speaking to (or about) Adam Driver, saying something along the lines of "don't go down that path I traveled all those years ago." Are you recoiling in horror? Good. That is the correct response.
