In this world there are many people who do evil then good. When you compare an elephant to a ant in terms of size, you will ignore the ant as its size is negligeble. So in this case the elephant is the evil in this world and the ant is the good in this world.
Actually there isn't any evil in the world. If you change POV's between the evil-doer you'll see. Unbeknown to billions of people the Nazi camps were not death camps, nor were they places to carry out human experiments. They were simply containment camps. Something had to be done with these destructive anti-social Jews who were strangling Germany. Thanks to the Jews, Germany had lost it"s moral code and had become debased and de-cultured, and that's just one example.
