Because we live inside of this assumption after ~500 years of a vicious cycle -
in which increasing "defensive" cruelty leads to degradation of the human condition across increasingly large groups of people, who (understandably!) eventually explode into a combination of rage, (often poorly targeted) violence, and monstrous atrocities, thus proving that we need even MORE "defensive" cruelty
- it can be super hard to see how it skews our perspective to discount entire eras of human history.
