The persons who have no knowledge about the humanity, think that they are advancing but actually they are diverted of all sense. They try to enjoy this beautiful world to the utmost limit and therefore always engage in inventing something for sense gratification. Such needless inventions are considered to be advancement of human civilization, but the result is that people grow more and more violent and more and more cruel, cruel to animals and cruel to other human beings. They have no idea how to behave towards one another. Animal killing is very prominent amongst demoniac people. Such peoples are considered the enemies of the world because ultimately they are invent and create something which will bring destruction to the world.
