Quote from : The Kite Runner Book

There is only one sin, only one, and that is theft. Every other sin is a variation of theft. When you kill a man, you steal a life. You steal his wife's right of a husband, you rob his children of a father. When you lie you steal someone's right to truth. When you cheat, you steal the right to fairness. There is no more wretched act than stealing. A man who takes what is not his to take, be it life or a loaf of naan, I spit on such a man. And if I ever cross paths with him, God help him.
