[Star Wars] How did Vader ... un-fall?

In the prequel trilogy, Anakin's forbidden love for Padme leads him to the Dark Side. Right. Maybe it's that he was scared, or angry, as a result of his love; maybe it was just love, there's little difference.

But ... fearing for his *son's* life turns him good again? Getting angry at his old master for taking his son away, and murdering him - the *same thing* that Luke refused to do to save his friends - redeems him?

Did Vader ever actually reject the Dark Side, or just Palpatine?

It's stated fairly often that the Sith think only of themselves, while the Jedi are selfless, and act for the good of others. In the moment he did something to save another, and willingly sacrificed his own life, the light had returned.
