After seeing this docu and how the nationalists normalized and rationalized the violence they had used, it kinda confirmed me humans are perfectly capable of every option in the book. It might seem gruesome but that's just from our perspective. Humans will write history in the way they see fit.

That being said, the point of society is building a systen where violence is avoided as much as possible.
