Even a cursory Google search shows how false your assumptions are. There were many external factors which regular North Korean citizens had no control over. Most accounts of the 'origin' of North Korea involve to some degree the proxy war between USSR and USA in the aftermath of the Japanese invasion in Asia. I doubt very much that "regular" North Koreans had any say in how some foreign governments decided to divide up and control their land. Follow that up with a great deal of propaganda, and you have a massively uninformed (or misinformed) citizenry controlled by the state.
