Sins are mistakes made in moments of weakness; everyone has weaknesses, therefore everyone commits sins. These uncorrected mistakes leave feelings of guilt and remorse, but since the nature of guilt is a feeling of responsibility for an action, it reflects someone's good because on a subconscious level they desire some form of redemption. The time taken by two characters in Khaled Hosseini's The Kite Runner to redeem themselves does not necessarily demonstrate their "goodness" but the level of guilt they felt due to their sins. We discover that the father, Baba, fathered an illegitimate child with his best friend's wife, a Hazara woman, who in turn forced him to hide his affair with Hassan, not to mention his negligent treatment of his legitimate child Amir due to their huge personal differences. Amir himself was a coward when it came to defending his half-brother Hassan, his sins worsened when he sold Hassan to bury his own guilt. While every character is good, Baba sacrificed more than Amir to redeem himself; although he was forced to hide his relationship with Hassan, he did his best to give him and Amir a better life and give back to his community. Weakness, as seen in Amir, refers to his childish selfishness. Selfishness for the father's affections and selfishness for one's own well-being; selfishness that forced cowardice played a major role in Amir's childhood, as he wanted to protect himself. Because of this, Amir's betrayal of Hassan, who was his unwitting half-brother, had repercussions that would last long into his life and negatively impact many people including Hassan, Ali, Sohrab, and himself. Since Hassan was Hazara, he was much lower in society than the Pashtun Amir. Amir has an inherent advantage over Hassan. Although Amir consciously recognized Hassan's status, he was still a very good friend of his.
