This was perhaps the best book I ever read, and since I've had my nose in a book constantly for about 75 years, that's saying a lot. I learned more about Afghan culture from that book than from anything else. When Amir was growing up, he was all about himself and not others.
He was selfish and self-centered in the extreme. Witness those awful scenes in the alley, where he betrayed his best friend by not coming to his rescue, and later when he rigged it to appear that his friend had stolen his watch, so that he and his father would be sent away and Amir wouldn't have to face his own guilt every day. But when he returned to Kabul to rescue that friend's son, he had grown beyond his earlier self.
He risked his own life to do this selfless thing, And then he went even further and took the young boy back to the U.S. and even into his own home. And a step further by remaining patient and forbearing when the boy rejected him. He showed the youngster love and kindness in the face of rejection, and never gave up on him.
He repaid his debt to his friend "seventy times seven", as the Bible says, and displayed his maturity in a most important way.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
