There are many villains through out The Kite Runner like the Taliban, but the main villain in the story for Amir is one-eyed-Assef. A childhood bully that prayed on kids that were smaller, weaker than he was. In the novel Kite Runner the author Hosseini writes a historical fiction to show us the life of two boys living in Afghanistan. Though out the novel our villain is big Assef that went from a childhood bully to a truly evil man in the world. The Kite Runner shows the readers how Amir changed through the book with someone like Assef in it. We know Assef will not be a good person later in life cause he says " About Hitler. Now' that's a leader. A great leader." (pg 39)By these short three sentences it can be shown Assef will never be a good person in life.
When Amir goes to America he forgets about Assef, and what happened to Hassan. In America Amir didn't really have a villain, but he is reminded of Hassan by a call from Rahim in Pakistan. He goes to Pakistan to help Rahim cause he is extremely sick, and he gets more than what he bargained for. Once he is in Pakistan he learns what happened to his home town while he was gone, and learned what happened to Hassan who had a child named Sohrab. When Amir goes to find Sohrab he finds out he as been taking by the Taliban from the orphanage. " He'll be the one wearing black glasses" (pg 257) The guy with the black glasses will know where he is. At his point of the book Amir as gained courage cause if he was still a little boy he could of ran like he has done before.
After Amir meets with the guy in black sunglasses he learns it's his childhood bully but worse. The black sunglasses is Assef holding Sohrab as a prisoner/ slave. Since Assef is with the Taliban he as the most power ever. " Door to door calling for men and boys. We'd soot them right there in front of their families." (pg276) Assef finds amusement in the story he is telling Amir about him killing innocent men cause they had the power to, and no one could stop him like back in their childhood. Since no one ever put Assef in his place he became hungry for more power, and being part of the Taliban gave him that. The power went to his head becoming a sick monster. "He kissed the side of Sohrab neck. The boy flinched a little" (pg 282) Assef has ruined Sohrab's childhood. To get the boy back Assef decided him and Amir are going to fight for him. Amir bloomed from a coward little boy to a man not going down without a fight. He knew there was a high chance he wasn't going to come out alive. Amir fights Assef which wasn't the greatest fight, but Assef does become one-eyed-Assef thanks to the trusty slingshot and Sohrab. After the incident Assef will probably never be the same like he was before.
