Agreed. Redemption does not mean that one is absolved of his crimes. Anakin paid for mistakes with his life. Redemption means that one can earn the forgiveness of those he loves through compassion and selflessness. Anakin acted out of compassion for his son, and therefore was redeemed. Does that mean his crimes were nothing? Absolutely not. What Anakin's actions did mean, however, was that he learned from his mistakes and sought to put a stop to the acts of evil that he had participated in up to that point. I don't mean to sound condescending here, but I think it's worth reiterating something that Lucas has said over and over again: Anakin was redeemed in ROTJ. He was the Chosen One. If people have a problem accepting that, then don't watch the film.
