The theme of man’s inhumanity to man is a theme which makes the reader think about how we torture each other because of our need for power in our lives. It is true as seen in this novel that there are essentially evil individuals who are impossible to redeem and that the evil they do affects all people around them. Assef is such a character. He enjoys hurting others physically, emotionally, and psychologically. However, there is also the evil found in all of us, no matter how good we are most of the time, which allows us to do bad things to those we love the most. The reasons may vary for why we commit such sins, but in the end, it is all about needing some sort of power in our lives. Fortunately, this evil is redeemable when we are ready to atone and right the wrongs we have committed. Amir is such a man. He is essentially good, but the evil he does as a child follows him into his adulthood and he must find a way to expiate those sins for his own sake and also for the sake of Sohrab.
The Kite Runner's most adoring readers and also some of its most critical are Hosseini's fellow Afghan expatriates. Hosseini said in a 2003 interview, "I get daily e-mails from Afghans who thank me for writing this book, as they feel a slice of their story has been told by one of their own. So, for the most part, I have been overwhelmed with the kindness of my fellow Afghans. There are, however, those who have called the book divisive and objected to some of the issues raised in the book, namely racism, discrimination, ethnic inequality etc." In addition to the deep feelings Hosseini's first novel aroused in the hearts of fellow Afghans, it also spurred a more lighthearted response, the resurgence of interest in kite fighting in America. The American invasion of Afghanistan may have 'put Afghanistan on the map' for Americans, but The Kite Runner goes farther by giving a detailed, human account of life and survival there. Its author continues this service to the world by serving as an activist in addition to writing. Hosseini has said, "If this book generates any sort of dialogue among Afghans, then I think it will have done a service to the community." As we know The Kite Runner has sparked conversation among Afghans and countless other groups of people worldwide. It is not such a surprise to Hosseini's admirers that a physician, accustomed to caring for people's bodies, has made such a graceful transition to caring for their histories and spirits.
