If we use genocide to defeat our enemies...
...only the adjectives will be different. It will all be barbarism.
You mistake humanity, which is an ethical concept, for humanness, which is a biological condition.
If you believe that humanness is all there is, then Saddam is equal in value to you, President Bush, or anyone else on this planet. He, too, has 23 pair of chromosomes. Evil is beside the point if ethics are irrelevant and biology is the only measuring stick.
Incidentally, Saddam appears to be quite at home with progressive technological barbarism. Do not become the thing you hate.
