As a poor ethnic Hazara, he is considered an inferior in Afghan society, and he is the victim of racism throughout the novel as a result. He is Baba’s illegitimate child, though he is not aware of this fact, and he grows up with Ali acting as his father. His rape is an early catalyst in the story, and even though he is not present in a significant portion of the novel, he plays a major role throughout. Baba – Father of Amir and Hassan and a wealthy, well-respected businessman.
Baba believes first and foremost in doing what is right and thinking for oneself, and he tries to impart these qualities to Amir. He also never lets anyone’s lack of belief in him stop him from accomplishing his goals. Although he distrusts religious fundamentalism, he follows his own moral code and acts with self-assurance and bravery. When necessary, he is even willing to risk his life for what he believes in. Yet his shame at having a child with a Hazara woman leads him to hide the fact that Hassan is his son.
Because he cannot love Hassan openly, he is somewhat distant toward Amir and is often hard on him, though he undoubtedly loves him. Ali – Acting father to Hassan and a servant of Baba’s. Ali is defined by his modesty more than anything, and he works diligently as Baba’s servant. He loves Hassan deeply, though he rarely expresses his emotions outwardly. Poor and an ethnic Hazara, he suffers from partial paralysis of his face and walks with a limp caused by polio.
Sohrab – Son of Hassan and Farzana. In many ways, Sohrab acts as a substitute for Hassan in the novel, and he is a central focus of the plot in the later sections of the book. He is also an ethnic Hazara and is great with a slingshot. His character arc takes him from being a normal little boy to the traumatized victim of sexual and physical abuse, and he goes from speaking very little to not at all. Assef – Hassan’s and Sohrab’s rapist and the novel’s antagonist.
Assef represents all things wrong in Afghanistan. A racist who wishes to rid Afghanistan of Hazaras, he is incapable of remorse and enjoys inflicting violence and sexual abuse on those who are powerless. He even claims Hitler as a role model. Rahim Khan – Friend of Baba and Amir. Rahim Khan is Baba’s closest confidant, and the one man who knows all of Baba’s secrets. For Amir, he serves a father figure, often giving Amir the attention he craves and filling the holes left by Baba’s emotional distance.
