While Amir’s father, Baba, had betrayed his son’s trust in deceiving him from his half-brother, Amir also sinned by failing to save Hassan from Assef. In addition, both father and son had betrayed Hassan. Thus, while both father and son escaped from Afghanistan, they carried their sins with them throughout the rest of their lives. Hosseini uses the motif of father-son relationships to show the continuation of sin between Amir and Baba. Thus, this motif allows for Hosseini to demonstrate how both Amir and Baba attempt to achieve redemption. Baba attains he own penance by taking care of Ali and Hassan, while Amir tries to save Hassan’s son Sohrab. A constant theme recurring throughout the novel is the concept of redemption. Hosseini is trying to show both the sins that Baba and Amir had committed, and the consequences of their actions. For Baba, it was a lifelong debt to Ali and Hassan whom he took care of like family, hidden behind his secret guilt. For Amir, it was a chance to forgive himself for his deceitful trick on Hassan while attempting to reconnect with his newly found nephew.
