"Since saddam is not a human but a beast.."
This is the mistake that we constantly make. Saddam is not a beast but very much an evil human being. Beasts follow their instincts and cannot be held responsible for their actions - Saddam knowingly acted the way he did and must therefore be held responsible. My dog is a beast and he feels offended for comparing him with Saddam.
Wrong. He is a beast in human shape - and thus whatever well-deserved abuse is meted out to him, at most it would be cruelty to animals.
