What's wrong with the DPRK? The only source that life there is terrible are defector's testimonies, which contradict each other on a daily basis and where the worst, most emotional stories are rewarded with fame and money. Often it's the only way to make ends meats for them. If you come to the south from the north you are a nobody.
Furthermore, the DPRK has never threatened anyone.
They have a 100% literacy rate (literally on the CIA website) and every citizen is guaranteed free healthcare, free education and a place to live. They use all of their arible land for food production but because of the sanctions and their mountainous terrain sometimes they have scarcities, but no one is starving. Their constitution is full of human and political rights and social gurantees.
And to proof that I don't shill for any country calling itself socialist, I don't like China at all (while still thinking that they are at least better for the world than the US).
And of course there are things to criticize the DPRK for, like the lack of LGBT rights and their weapons exports and hackergroups. But considering the sanctions (that even China upholds) they are in very dier need of foreign currency.
I would also encourage everybody to study the history of Korea.
