One way in which Amir's personality and attitude impacts the reader's understanding of The Kite Runner is how it shows that redemption is possible. Rahim Khan's opening "a way to become good again" strikes at the heart of Amir's evolution throughout the course of the narrative. Seeing both how low Amir can sink and the heights to which he can emotionally climb are examples of how the reader understands the course of redemption in the novel. Amir's personality and attitude both experience massive change. This change is where the reader is impacted in the course of the novel's development.
Amir's personality and attitude also impact the reader because it reminds the reader of how individuals can act and how this action is seen in the hopes of what can be. The reader is impacted by Amir's personality and change because it reflects the capacity for change that exists within the individual. Amir might believe in the authenticity of his beliefs and the certainty of who he is. Yet, as evidenced when he finds out the truth about his father and his relationship to Hassan, Amir's personality and attitude become fundamentally changed, reflecting that experience and being in the world can change individual perception. The reader recognizes that events, revelations, and understand can fundamentally alter the individual's sense of identity. This impacts the reader for it causes reflection and identification to Amir's personality and attitude.
