Hassan is Amir's closest childhood friend. He is described as having a China doll face, green eyes, and a harelip. Hosseini regards him as a flat character in terms of development; he is "a lovely guy and you root for him and you love him but he's not complicated".[16] The reader eventually discovers that Hassan is actually the son of Baba and Sanaubar, although Hassan never discovers this during his lifetime. Moreover, it would make Hassan a Pashtun according to tribal law and not Hazara as he's actually the son of Baba, and ironic for Assef to bully him as both Assef and Hassan are half Pashtuns. Hassan is later killed by the Taliban for refusal to abandon Amir's property.
