I'd imagine he's going to be coming out of his bolt-hole in the next day or two personally. He's done a dissapearing act before turning up fine later on.
With regards to the North Korean people there gaining "Freedom" from his death; That's an ideological fools dream. It'll never happen so long as there's enough of a grip by those with military power who want things to remain as they are; whether they were conditioned to think like that or truly believe it's them vs the world, etc. So this will never happen, not without an actual Leader of North Korea slowly guiding it towards a different path. Otherwise, there'll just be a power struggle.
But that's not the worst of it; all it'll take is one power mad, power grabbing wannabe to possibly ignite their still growing nuclear arsena on the (local?) world stage. It's never more apparent that having the Devil You Know here (Kim Jong Un) a gluttonous, self absorbed, celebrity fame hungry North Korea Leader like Kim Jong Un is better than a new one wanting to "prove their worth/mantle", and bring glory to their name and place in history, and end up being far worse than Kim Jong Un.
We've seen stuff like this before in Iraq with Saddam Hussein; his removal lead to destabilisation in the region, and if they had nukes, those may have been deployed or taken by others. And that is not a good position to be in.
