There's only one sin

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 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.
