Mankind is mad.
Mankind therefore, took the wrong path and that explains what a disaster the evolution of man has been. Mankind took the route of aggression, conquest, battles, murder, killing and genocide. We, therefore, live in an insane world. There are many days when I shake my head in disbelief, become despondent, discouraged and disgusted at the goings on in the world and in my own country. It doesn't relieve the pain but it does make living easier.
