In times of doubt....

From the book, The Kite Runner: 

The narrator in the book, Amir, tells about the time when he was a boy, the mullahs in Afghanistan said drinking alcohol is a terrible sin. He relayed the lesson to his father, Baba, who drinks.

The father made him sit on his lap for serious talk: "No matter what the mullah teaches, there is only one sin, only one. And that is theft. Every other sin is a variation of theft. "

The father continued: "When you kill a man, you steal a life. You steal his wife's right to a husband, rob his children of a father. When you tell a lie, you steal someone's right to the truth. When you cheat, you steal the right to fairness."
