Defined by Success, Danielle Sison

Amir believed in order to win his father's love he must win and be successful. But I do not understand how Amir's success would make up for his father's sins. If Amir got the better half of life, how does "being a man" make his father happy? Wouldn't Amir's success represent what Baba has denied his other son? What can Baba gain from the success? When Amir won the kite tournament, he and Baba decieved themselves in the transformation of their relationship. Amir sacrificed Hassan for Baba's love. He had to pay a price, and he found Baba's affections to be tainted with guilt. But why did Baba decieve himself?
