One notable case where we did get to see it play out (post-immortem) is Darth Vader's redemption.Not sure I agree with this. Literature is full of evil characters who undertake a single grand act of goodness, which is implied to redeem them. Problem is, goodness is usually defined in terms of self-sacrifice, and a grand act of goodness requires a correspondingly grand sacrifice, which is usually fatal to the person performing it; so we don't get to see how the redemption plays out.
