Why is The Kite Runner impressive?

I have been looking forward to the day when Amir will say "I'm sorry" to Hassan, and he will redeem his debt to Hassan with practical actions. However, poor Hassan died, and his death was still to protect Amir's home.

Hassan will never hear Amir's apology, although he has forgiven Amir's behavior.

"Here, there is a way to make you a good person again." Racine Khan, who was seriously ill, wrote a letter to Amir in America, showing him a bright road to redemption.

Amir let me down again-

He doesn't want to go to dangerous Kabul to rescue Hassan's only son and pay his debts to Hassan.

"I have a wife, a house, a career and a family in America. Kabul is a dangerous place, you know, you want me to take all risks, just to ... "

"Just for what?" Amir stopped, and the screenwriter didn't write what Amir wanted to say. If the writer writes his heart, Amir's 26 years of pain will become a joke. Because that sentence is: for a Hazara boy, you let me risk everything.

If Rahim Khan doesn't tell the secret that Hassan is Amir's half-brother, I don't think Amir can save Hassan's son Solabo at all. At most, he will spend symbolic money to find someone, and then add a sum to the debt owed to Hassan.

Although the novel lays a lot of groundwork for Hassan to be Amir's younger brother, I still don't like the setting of the novel. Because Amir's road to redemption is based on Hassan being his own brother. If there is no blood relationship, his guilt for Hassan is not enough to support him to go to dangerous Kabul to save Hassan's only son.

As a Hazara, Hassan's loyalty and sacrifice to Amir is still not enough to make Amir, a Pashtun, atone for his sins with practical actions. This redemption is hard.
