Clearly you guys have not met my 11 month old son who finds joy in picking up the heaviest object around and smashing the smaller chldren. Natural Selection. In most cases, humans are oppurtunists who will destroy another human if it benefits them in some way, shape, or form. If mans kindness and love could save anything, it would have a long long time ago. Its blood and sweat that make changes in the world, not hugs and kisses. That isn't to say we shoudnt be kind to one another, but making ourselves all important is a joke. Humans are pretty insignificant in the big scheme of things.
