Our culture, society, media, leaders all teach kids that Life is essentially without meaning, with only an assigned value, without intrinsic worth. They learn that Life is disposable, a commodity and the taking of Life is the ultimate groove because each child aborted is a step toward saving the Planet.
Is it any wonder that thrill kills are so in fashion?

When you raise children in a society that does not value life then you will have children that kill without remorse. Also, I suspect this guy has probably been on Ritalin or other similar drug since childhood.
