How much is Saddam worth?

Saddam is sentenced to death. Who cares? Does Iraq care? What will it solve? What message does it give and to who? After all its not the Saddam supporters who are fighting in Iraq. A criminal should not be hanged if the only reason is revenge and not to give any message to other similar criminals. Hanging him would neither give any message to anyone nor will it solve any problem. He has lost his regime, he has lost his commanders and I don't think he has any clout to come back. He should be either sentenced to life imprisonment or exiled.
