From Ali, I see a kind of loyal due diligence, which is also reflected in Hassan. He did not hesitate to protect Master Amir, even if he sacrificed his own life. This seems to have gone beyond the word loyalty. This is the best for a true friend, or perhaps it is the instinctive reaction of this half-brother love. In any case, this reflects Hassan's brilliant humanity and selfless dedication.
Amir has always felt guilty for his cowardice and selfishness. Hassan has already forgiven him and never mentioned the past again, as if nothing had happened. He is still smiling in the photo. And Amir, the hero of this book, although he is too timid and selfish and has made some mistakes that may never be made up, he always bears this guilt, which shows that he is still a kind person.
In the second half of the book, he mainly tells the process of self-help. When he learned that Hassan was his half-brother, he regretted it and risked his life to save his nephew. This is a manifestation of self-redemption. It is not terrible for people to make mistakes, but it is terrible not to know that they are wrong.
I was deeply impressed by a sentence in the book. "When crime leads to good deeds, it is truly saved." People will inevitably make mistakes in their lives. In the face of these mistakes, we should not escape, but try to make up for them. Even if we can never make up for them, at least some good deeds can free us and reassure us. This is exactly what I learned from Amir. At the end of the story, Amir is still chasing the kite of humanity.
After reading "The Kite Runner", I learned from Amir to turn sin into good, and from Hassan that "for you, Qian Qian has done it for thousands of times". I also began to chase the kite that can only decorate my life and make it shine.
