If it's in our "nature" how is it that the vast majority of us are not doing it?
If we look at early human societies they were mostly relatively egalitarian and peaceful. The Hobbesian view of humanity is very useful to make you accept the unacceptable.
To explain away the man-made horrors of the world as being “human nature” is taking the easy route by avoiding questioning what causes the worst things to happen in the world and coming to a shitty catch-all conclusion.
It’s also super defeatist and can stop discussions on how to fix the crimes of those before us.
