After reading "The Kite Runner"

There is only one sin in this life, only one. Ant that is theft. Every other sin is a variation of theft.

Confusing, isn't it?

When you kill a man, you steal a life. You steal his wife'e 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.

Do you understand now? If still not, try to think about it.
