What are the important points to note while doing psychoanalysis criticism of the kite runner by Khaled Hosseini?

This novel touches upon some issues that have
psychological ramifications. For example, the destructive effect of abuse. When Hassan
is raped, it affects him in a profound way psychologically. Also, later, when his little
son is kidnapped and raped by the Taliban member (who turns out to be Assef), this
abusive treatment has almost destroyed the boy mentally. The complex relationships
between fathers and sons is important to discuss. Amir's relationship with his father as
a child while they are in Afghanistan differs from their relationship as men, when Amir
is grown and can understand his father's actions from an adult perspective. Growing up
as a child, however, Amir never felt accepted by his father. He always felt that his
father loved Hassan more, so this can be explored. How did this constant striving to be
accepted by his father affect Amir's adulthood relationship with his father? Also, how
does finding out the truth about Hassan, that he is really Amir's half brother, affect
Amir psychologically? Finally, I think it is interesting to explore why Hassan was so
devoted to Amir. What made him, as a child, grow up with such fierce devotion? Amir
mistreats Hassan and even frames him for stealing, and yet Hassan never wavers in his
adulation of Amir. Amir does not deserve this admiration, and yet Hassan is steadfast
and keeps trying to win back Amir's favor.
