I encourage you to read Humankind by Rutger Bregman. The notion that humans are inherently animalistic, greedy, and violent has not been supported by the bulk of anthropological study throughout modern history, and his book does a good job of breaking down why there’s such a divide between the perception of so-called “human nature” and the anthropological and sociological evidence.
TLDR: humans aren’t inherently greedy, we respond to our systems and environment more than anything.
What your original comment suggested was not that you acknowledged the human capacity for violence, which nobody can deny and I am not debating.
The comment implied - and this is an assumption so ingrained in our western society that nobody could blame you for it - that the only thing separating humans from violent, animalistic, or selfish impulses is societal structure and policing.
That just isn’t demonstrable, as much as it may feel intuitive. It’s a Hobbian philosophy.
I’m not here to pretend I can convince you otherwise in one comment thread, took me a long time to change my mind on that and I’m not anthropological authority. That’s why I recommend the book, it’s quite eye-opening. At least it was for me.
