In The Kite Runner, why do you think Amir ran away from Hassan after the tournament? Was he hiding from the bullies or from himself and Hassan?I...

There is no doubt that Amir runs away in fear. A boy his age is immediately going to be afraid that if he interferes, the other boys will rape him as well. Part of it is also his jealousy over Baba's feelings for Hassan. Amir wants to become closer to his father and resents it when Baba takes notice of Hassan. I think this adds to the guilt Amir feels and why he's willing to plant "stolen" money and objects in Hassan's bed. True, he wants to be rid of Hassan because he's a reminder of Amir doing nothing to help Hassan, but I think this also proves that Amir is willing to sacrifice Hassan and their friendship for whatever Amir wants.
