In Kite Runner, Amir is a nonathletic intellectual boy who delights in stories and kite flying. His servant and friend Hassan has an uncanny gift for knowing where downed kites have fallen and therefore can fetch a downed kite quickly right to it. Though the course of the story, Amir changes from pampered, unloving, envious coward to a man of conscience and humility with a desire to do right.
In the beginning of The Kite Runner, Amir is a boy and lives with his father Baba because his mother has died. He is jealous and envious of the attention his father shoes to Hassan who has more of the qualities Baba wishes to see in his own son. There is therefore an uneasy friendship between Amir and Hassan who forgives Amir every time he tricks him or takes advantage of him.
When war rages, Baba and Amir escape to the United States but they leave Hassan--who is just a servant no matter how admired he is--to face the war alone. After reaching adult and becoming a success as a writer, Amir regrets his bad treatment and betrayal of Hassan. On one occasion, Amir witnessed a brutal attack on Hassan and said nothing about the crime committed, thereby betraying and deserting Hassan. On another occasion, Amir falsely accused Hassan by telling Baba that Hasan had stolen from them. These large things eat at Amir's conscience along with the smaller jealousies, envies and unkind mistreatments and Amir returns to his homeland to find Hassan and make things right--if he can.
