Perfect heroes are unrealistic in literature because even if they seem ideal, the characters become flat and inaccessible. Therefore, authors often add other dimensions to characters that reveal their personality flaws and errors. Authors are able to use these dimensions both to connect characters, but also to teach readers life lessons about the characters' mistakes. For example, in The Kite Runner, Khaled Hosseini creates several ambiguous characters who are good people who make major mistakes. By contrasting these characters with purer ones, Hosseini is able to show both the ideal life to live and the means to achieve it. In The Kite Runner, Amir and his father, Baba, display contradictory lives while Hassan and Rahim Baba are shown as an immoral man at home because he doesn't love his son and cheated with the wife of his friends and had a child. Even some of Baba's qualities, such as his concern for Hassan and Ali, his father, seem to have a selfish motive, as he wants to keep his son close to him. Although Baba is never the father figure in the first part of the book, once they leave their home, Baba seems to care much more about Amir. This may happen because he doesn't always have Hassan by his side to remind him of the terrible mistakes he made in the past. However, even when Hassan leaves, Baba still cares for him. Even though Hassan may be a symbol of past mistakes, he is ultimately Baba's son and the family still maintains strong bonds. Therefore, Baba's character shows his moral side because instead of hating his illegitimate son, he takes care of him as much as he can, considering the cultural norms of the two opposing religions. By healing his cleft lip and remembering Hassan's birthday every year, Baba is able to show his caring side which is rarely seen in his relationship with Just like Hassan is Amir's main juxtaposition, Rahim Khan is the juxtaposition Baba's main. During Amir's childhood, Rahim Khan is the caring, fatherly figure that Baba should have been. Rahim Khan encourages Amir's writing and is the reason why Amir ultimately continues writing. However, it should have been Baba because it is a father's job to always love his son unconditionally. But more than that, Rahim Khan also seems to be an all-knowing figure in the house. He knew about the rape and that Amir had witnessed it but did nothing. However, this knowledge could be used for anything. Instead of using it to take advantage of Amir, he uses this knowledge to sympathize with Amir. Just like any father should, he takes Amir's side and supports him even though Amir doesn't deserve it. He writes a letter to Amir and tells him not to feel guilty for what he did. Even in person, Rahim Khan tells Amir “[insert quote here]”. Rahim Khan has no reason to care about Amir and be nice to Amir and yet, unlike Baba, he does. It shows that love and care don't need a reason. This is something that Amir and Baba seem to struggle with throughout the book. Only after radical changes in their lives do they begin to realize that they need to care about others.
