It forms when one race feels superior over another and evolves as hostility towards this other "alien" race increases. The book "The Kite Runner" covers these issues of racial discrimination. Not only does the book depict the relationship between a young boy named Amir, and his servant named Hassan who has always been treated poorly because of his dissimilar racial background, but it always provides evidence of how Hassan's mistreatment influences Amir to become a better person.
At the beginning of the book, "The Kite Runner", Racial conflicts did not stop Amir and Hassan from hanging out together as they were basically raised in the same household. Hassan was Amir's servant but that did not stop them from playing with each other and reading books together.
As we further dive into the novel, we realize that Amir feels almost embarrassed to have Hassan around and does not consider him as a friend just because of the way everyone else treats Hassan; they all mock him. Hassan would get called "mice eating, flat-nosed, load carrying donkey" (Hosseini 9) and Amir would only agree with the fact that Hassan was a Hazara who did not belong in a town filled with Pashtuns. Amir lacked to stand up for his friend that had been with him his whole entire life and simply ignored the fact that Hassan and him "fed from the same breasts" (Hosseini 11).
As the book continues, Amir further distances himself away from Hassan as more people mock and harass him for his looks and racial background. After watching his own friend get sexually abused by the kids in town, Amir attempts to cut all ties with Hassan as the guilt of not doing anything makes him feel as if he "was the monster that grabbed Hassan by the ankles and dragged him to the murky bottom" (Hosseini 75).
Amir feels as if he was the monster pulling Hassan down because, after everything Hassan has done for Amir, Amir did not have the courage to stand up for his friend during the one time he needed him the most; Amir was deeply impacted by this situation and felt awful about it. Instead of doing the right thing and apologizing to his friend, Amir continues to hide his thoughts and tries his best to get rid of Hassan.
Towards the end of the novel, Amir goes to America while Hassan stays in Kabul. During their separation, Amir's perspective on Hassan changes for the better as he feels even worse about himself. As he talks to Rahim Khan when he comes back to Kabul, Rahim Khan reminds Amir about the conversation he had with his father about how his father was worried that "Amir would not stand up for himself because he was cowardly" (Hosseini 221). After Hassan's death, Amir finally realizes he must do the right thing and stop being the coward his father said he was. The words coming from Rahim Khan and the thought of losing a friend he betrayed and treated poorly persuaded Amir to finally help Hassan by getting his son Sohrab back from the orphanage in Kabul.
