Theft

I'm reading The Kite Runner by Khaled Hosseini. His main character, Amir, quotes his father, who has little respect for religion but much respect for Afghani customs and moral behavior. Here is his unusual take on theft:

"Theft is the one unforgivable sin, the common denominator of all sins. When you kill man, you steal a life. You steal the 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. There is no act more wretched than stealing." (p. 106)

Interesting take on human behavior and its repercussions. What do you think?
