Best of Week: Did Amir really earn his redemption?

This week, someone brought up the question: did Amir really earn his redemption, or was it just given to him? I thought this was a very good thought. When I thought about it, I found that I thought that Amir did not earn his redemption. He left Afghanistan and his whole situation with Hassan and moved to the United States, and hoped to bury his memories of what happened with Hassan. By forgetting about his mistakes and not trying to help himself, Amir was not attempting redemption. Then, years later, Rahim Khan called him and offered him a chance at redemption. He specifically said, "There is a way to be good again." Amir felt so much better when he went to Afghanistan and fought for Hassan's son. However, what did Amir do to earn this redemption? He never actually said he was sorry to Hassan, and he never went back to Afghanistan to try to see Hassan or help him years later. At the very least, he never even looked for a way to receive redemption. He does get some credit because he (physically and mentally) fought for Hassan's son. I just don't believe that Amir deserved or worked for his chance at redemption. It was simply handed to him.
