Human Nature

[Alan V]

I suppose this question falls under the heading of psychology: What do other atheists think about human nature in general?

In the last decade or two, because of ongoing brutal wars, the election and reelection of Donald Trump, the repeatedly absurd rationalizations of theists, and our continued neglect of climate change among other reasons, my opinions of human nature have become much darker and more misanthropic.  I don't really know whether I am becoming more realistic or just worn out with old age.

I assume other atheists will be much more reasonable than most people would be about such a question.
