Why do you support NK polices

I understand not all communists are like what I'm about to describe, but there's definitely a noticeable amount. I want to make this clear: supporting communism doesn't equal supporting NK automatically. I'm fine with people supporting communism in the sense that they are against 'imperialism' or whatever, but there are communists who will die on the hill that the way NK treats their people is good and 100% fair, better than the majority of well-developed capitalistic countries.

I'm aware there's a lot of propaganda pushed onto NK, and it's important to fish out what's true and not. A good place to start is looking at the massive difference in how NK treats people compared to how SK treats people.

It is 100% undebatable that SK allows its people to have way more freedom than NK, from learning about different cultures to leaving the country easier and without worry. Legally, NK prohibits its people from legally leaving the country and living somewhere else where they would like. To me, this should be against the communist ideology, no? Why must you go against someone's wishes that won't hurt others? Isn't the idea about giving more freedom to the people and choice?

I can understand why they wouldn't be okay with people coming in and allowing their people to have more access to the internet and view other societies because other nations may try to do something with that opportunity. But on the other hand, it might reflect poorly if people see others and deem it way better than the one they live in, but I'll let that one slide.

Daily NK, which is a group based in South Korea but made by people who defected from NK, brought to light about two minor students being arrested for listening to K-pop. To me, this is utterly disgusting, and I want to know how the NK policy supporters rationalize this. How could you support a country that will punish you severely for listening to K-pop? This isn't the only case of this; even movies shared between students can result in death or imprisonment. Again, I'm looking for die-hard NK supporters and wanting to hear their reasoning for thinking these practices are just. I don't want to hear the argument that the people choose, therefore it's just by default because the island hypothesis comes in with one family, and the family may choose that disgusting acts of violence towards their offspring are okay.
