Funny thing is, to try and start to undo all the damage that he and his father did to North Korea, all the people would have to do is to wake up one morning and say "Fuck it, all we want is decent, respectable lives and our dear leader is fucking us in the ass". There would be absolutely nothing their government could possibly do and they would find themselves hung by the nearest tree that same afternoon.
All that's in the way is the mental trance of worship and ignorance. It's only a mental prison, not a physical one.
