Who was the most likable character and who was the most despise character?

I really like the character of Hassan. He is Amir's most loyal and devoted servant, who is born with a clept lip. He and Amir were nursed by the same woman and, unbeknownst to them both, they are half-brothers. Hassan is illiterate but smart and stands up for others. He is also the best kite runner in Kabul. He dies at the hands of the Taliban, defending Baba's house from takeover. He is completely loyal to Amir despite the cruelties he must endure. For Amir, he will do anything with a happy heart, For you a thousand times over!
