Human life is of infinite worth.
That's the message of the cross. That's the message of the Resurrection. God, in the person of the Son, became one of us. The divine nature was joined to the human, that life died, and rose again. Death was conquered. Life affirmed to be more than death.
The infinite value of human life is violated every time a life is taken, every time a person is abused.
That's why the terrorist attacks on 9/11 were such a horror. Thousands of people dead. Not thousands of Americans, thousands of people.
And now Osama bin Laden is dead. And it's a sad thing. It's probably a good thing, the world is probably better for it, but it's sad. Though it be good that he is dead, rejoice not. Gloat not. "Do not rejoice when your enemies fall,
and do not let your heart be glad when they stumble” (Proverbs 24:17). Or, as the Tao says, "This means that war is conducted like a funeral. When many people are being killed, They should be mourned in heartfelt sorrow" (Tao 31).
Or you know, Jesus, "Love your enemies."
As Rod over at Political Jesus said, "that Jesus, just such a party pooper."
