NK citizens for the most part are probably fully indoctrinated and have something akin to Stockholm syndrome. I've watched enough of both openly recorded and hidden camera footage to be convinced of that. But, no doubt, especially among the many who have seen their family and friends disappear to the concentration camps, there is loathing-type fear, more than obedience/worship-type fear of the govt.
But for the most part, they probably really do hate and fear all foreigners other than the Chinese. However, should a war be fought, in the aftermath, offering lots of decent food to all the NK civilians and disarmed soldiers would quickly light up some good feelings, curiosity, and earn some trust.
They have been controlled and trained through food access control for so long, suffered so many famines, that doing something so simple could quickly win them over.
