The idea of betrayal displayed in the story helped understand past events that had not given the reader clarity. For example, when Rahim Khan confessed to Amir that Baba was also Hassan's father, Amir reacts the following way, "I was learning that Baba had been a thief. And a thief of the worst kind." This quote reveals the connection Amir makes between discovering his father lied to him and a conversation they had about the worst sin in Baba's eyes, stealing. Clearly, the development of this betrayal helps Amir comprehend why his father acted the way he did. In addition, once Amir processes what he has been told, he then concludes this about both his father and himself, "We had both betrayed the people who would have given their lives for us." Clearly, Amir now believes Baba and him were not all that different because they both deeply regretted their past. The betrayal helped develop comprehension of Amir's childhood experiences.
In this novel, the development of guilt also caused a lack of honesty between Amir and two of the most important people in his life. For instance, when Soraya talks to him about her past with another man, Amir accepts her but does not confess his own past to his fiancee. He had the opportunity to say something but instead he does this, "I opened my mouth and almost told her about how I'd betrayed Hassan, lied, driven him out." This quotation illustrates the hesitation Amir feels when it comes to being truthful about himself. Clearly, guilt plays a role in his decision to remain silent about his past. Similarly, once Amir learns about Baba's secret, he expresses how he feels about Baba lying to him for most of his life by saying, "I think he was ashamed of himself." Amir decides to accept Baba's guilt for his actions despite the fact they both hid secrets of their own. Clearly, the constant lying was caused by the guilt both characters felt throughout the novel.
