Expand your perspective anon. From a cosmological perspective man is just a part of the thin film of organic life, along with the animal and vegetable kingdoms, covering the being known as Earth and transmuting impressions between Earth and the starry worlds.
Nature requires both good and evil, and makes use of them both. What is missing is the resolving force.
But you're right. Man is a very broken machine. Man doesn't perform his cosmological functions very efficiently (perhaps that's why there are so many). So poorly, in fact, that he has become something else really.
Man has become Hu-man.
‘War is the result of the slavery in which men live. Strictly speaking, men are not to blame for war. War is due to cosmic forces – to planetary influences. But in men there is no resistance whatever against these influences and there cannot be any because men are slaves.’
