And why does it have so many fans and views? I don't think I know anyone who listens to it and the Americans that apparently do I highly doubt they understand Korean.

If you read Korean comics online, they idealize and fetishize abusing those weaker than oneself. I'm not even slightly surprised by the state of North Korea after exploring a bit of South Korean culture.
