Some news sources saying he's dead, some saying he's been perfectly fine. Which is it?

Hopefully dead, but then again, that would mean replacing him with another git with a god complex and a stupid haircut. By this logic, Karen could potentially be the new leader of North Korea.

South Korea says he's "Alive and Well" but who knows...

Alive, maybe. But a man who starves and enslaves his own people to literal cannibalism just to build up his military is anything but well.
