For the first two, refer to what I replied to MegadrummerJ. These are just tired arguments that are extremely disingenuous at best, really.
And for the DPRK, it is unbelievably easy to make shit up about it since it’s so secretive. And people do, either for ideological purposes or for cheap clicks. Trust me, go to any article relating to it, check the sources (if you’re lucky enough there are any), check the sources of said source, check the sources of said source about said source, and chances are that, by then, the sources will either be nonexistent or anonymous.
“But what about the defectors??” I see you angrily reply with enough copium to kill a small horse. This is not to say that every DPRK defector is lying, but a lot of them do for monetary reasons. Take Yeon-Mi Park, for instance. She famously said that she witnessed someone get executed for watching Titanic, to which other defectors had basically said she’s lying, and Andrei Lankov, who is definitely no fan of the DPRK, had stated "I am very, very skeptical whether watching a Western movie would lead to an execution. An arrest for such action is possible indeed, but still not very likely." Keep in mind this is just one examples of many.
