How does Hassan and Amir represent religion in the Afghan society in The Kite Runner?

Hassan represents the lower class, strict adherence to
Muslim beliefs. He has little education, and he follows his faith and its teachings to
his unfortunate demise. His is a blind loyalty to the faith in which he was raised. Amir
represents the middle class who has had opportunities for education. The more education
people have, the less blindly they follow their childhood religious teachings. More is
open to question than relying on blind faith. Amir is torn in his religious beliefs, and
spends much of his life trying to please his father and reconcile his religious
beliefs.
