in my opinion, no matter who, with age grow up the thought constantly changing, but the deep of people mind will not change,people will still keep it from born to die, this is like essentiality. god created people and he give people a different character we have to keep it and we can not change it.
like Amir, when he grow up always think about Hassan, when Rahim Khan call him go back Kabul he was try looking for an excuse to refuse him,like he has wife can not leave her or something else. because he is afraid to face his past, this is his inbeing same with when he was young try to avoid his responsibility. finally he go back to kabul. why? as i say with age grow up the thought constantly changing, he grow up, he became maturate and responsible.He wanted to be held responsible. but in the end he still can not face Hassan's son and do not want to bring him take care him. why? because his inbeing! he is afraid to face his mistake.
