I see your point Diane771 in the difference between redemption and repentance. However, I feel that Edward did repent and by the end of BD, I wonder if he felt the redeemed? I believe he was redeemed when he met Bella. What if Bella was the reward for returning to the path of the righteous? True, a test in a way to see if he was truly worthy, which he past and gained his soul mate. I wonder, now that his mate is a vampire and how Bella is as a vampire, if his attitude about being a monster has changed. Does Edward think he has been redeemed by the end?
Well this is my point that repent is being sorry for what you did, and by Edward thinking himself as a monster who kills people don't you think that he is repenting wish one had not done, resolve not to continue Edward was repenting everyday he returned to Carlisle. The redemption does come with finding true love and focusing on the good in yourself and not the bad.
Yes that is a great Idea UNA Edwards redeemed by the end. I do think she brought to his life the hope and faith in himself again and so yes I do feel he was redeemed. He is living a clean life and has a wife and child and not focusing on that "monter" he thinks he is. I don't believe at all that he thinks Bella is a monster, so he is seeing a vampire through a different perspective. It just what I think.
