It's not starving its people to death though. Many people are on the edge of poverty, sure, but you will find exactly the same thing in USA, South Africa, Phillipines etc. I have been to Pyongyang and driven though country areas in North Korea so I've seen how good and bad it is.
The human rights abuses are what is truly shocking but again some of the things that go on in China, USA, Phillipines, Israel/Palestine for example are also truly shocking.
