Discuss the idea that in rescuing Sohrab, Amir finds redemption not only for himself, but also for his father.
Even though the relationship between Baba and Amir shows strain and features the stress of modern life, Baba still wishes for the best with regards to his son. While he might not be able to fully immerse himself in the way Amir appropriates the world around him, it becomes clear that Baba loves his son and does what he can to respect him. One of Baba's fundamental misgivings about Amir is that he cannot stand up for himself or embody that which is right. When bullies threaten Amir and Hassan, Amir flees, while Hassan fights. For Baba, this lack of moral fiber and intestinal fortitude causes great regret.
In rescuing Sohrab, Amir finally stands up for something. It is redemption for both himself and his father's wishes of wishing to see his son fight for his beliefs. In having to engage in a physical altercation with Assef, Amir's father finally receives the redemption he has yearned. Even if he is not there to see it, one gets the feeling that his soul would be pleased with how Amir finally stands up to the bullies of his youth in defense of something good and right. Baba's wishes for his son that he represent a sense of toughness and rugged goodness are honored in how Amir stands up and rescues Sohrab.
