North Korea runs contrary to my intuition about dictators. Don't get me wrong, I'm a big supporter of regicide, but most dictatorships, even among the most horrific, represent some sort of misguided attempt at benevolance.
Killing dissidents? Sure, they're getting in the way of your utopian plan. Failed economic plans that lead to famine? Well, the idea had some justification, better pivot to avoid further harm. Hell, even overtly fascist ideologies have some subset of the "common folk" that they attempt to promote.
North Korea's leadership doesn't seem to have any interest at all in the wellbeing of the populace. I'd expect radical, top down changes to be common place until they found some solution that didn't have almost half of the country malnourished. Yet they just seem to double down, consistently.
