Isn't pancreatic cancer one of the worst possible cancers you can get?
I'd say that it's good that the megalomaniacle, unstable, autocratic threat to everyone and everything around him is on his way out, but I've got to worry that having a terminal cancer is going to do bad things to ol' Kim's already ample supply of crazy. The nutty bastard might try to take everyone else out with him and launch a nuke somewhere that'll make all the fingers on the red button a little twitchy.
Though I don't see it doing much good. His repressive regime is likely to outlive him if he doesn't decide that ending the world with a bang would be a whole barrel of laughs. It'll just mean we'll get his nutty SON, instead, who is apparently a chip off the old block.
