In the novel, strength of character is a recurrent theme. Amir commits a sin against Hassan, his best friend, and he does not reach atonement until the end of the story. Amir does not have the strength to redeem himself until he speaks to Rahim Khan and goes back to Kabul. He merely tries to hide from all memories and thoughts of Hassan. Amir also learns that Baba, whose strength he always admired, also lacked in this area, strength of character. This occurs when Amir discovers that Hassan was his half-brother. The fact that Amir and Hassan both fed from the same breast symbolizes brotherhood and somewhat foreshadows the fact that they are related by blood. This symbol of brotherhood is reflected at the end of the novel as well when Amir continues his relationship with Hassan through Sohrab. Kabul itself can be viewed as symbolizing both weakness and redemption, for it is here that Amir begins and ends the guilty, shameful, confused period in his life.
The novel is written in the first person from Amir's point of view. As the narrator, Amir develops various tones throughout the novel. At the beginning, there is a compassionate tone that reflects in Amir and Hassan's deep relationship. The tone becomes violent and fearful whenever Assef is introduced into the story. During the story of Amir's life in America, the tone is somewhat detached because Amir is lacking in a relationship like the one he shared with Hassan. It does become more optimistic, however, once he marrise Soraya.
Situational irony exists when Baba pays for plastic surgery on Hassan's harelip so that he can smile and display his outgoing, loving personality. The next winter, however, something happens that makes Hassan stop smiling--his rape, Amir's betrayal, and the downfall of Hassan and Amir's relationship.
The major controversial language in the novel occurs in the rape scene in which Hassan is raped by Assef. Some parents do not find this scene appropriate for their children to read, as it deals with a sexual act of harrassment.
