Not GP, but his education in Switzerland clarifies the fact that the leadership does not believe the propaganda they give to their populace. Kim is very aware that the promise of better living conditions is not a "lie manufactured by the West." He knows how bad his people have it compared to the rest of the world and still chooses to run his country the way he does. Food shortages are not a thing in Switzerland and also not a problem in his palace, but they are in other parts of DPRK.

So maybe his Swiss education doesn't make his citizens worse off, but we do know it's not some misled idealist at the helm, but rather a dictator that knows full well what he's doing.

It certainly didn’t improve things either. He is a murderer like the rest of the family.
