Okay, if you want to play semantic games with the word death camp you're more than welcome to. It's weird you feel the need to defend North Korea or draw moral equivalency between North Korea and South Korea when there is none.

The source you linked mention 50 people. North Korea has political prison populations in the tens of thousands.

There is a lot of criticism a person could level at South Korea, such as its people are overworked and a lack of social welfare programs that have allowed people to starve to death in their homes. Capitalist countries are not without their issues, but it's weird the indignation stops at authoritarian countries.
