It's a classic case of 'suicide by cop'.
Dude's got the country so fucked up, he knows it's over. And he's crazy enough to try to take the rest of the country with him into oblivion rather than see Korea united and westernized. As a bonus, an attack by the US would help to polarize its opposition.
Seems like a case where it would clearly be in the best interests of the rest of the world for a North Korean group of malcontents to take matters into their own hands and rid their country of this psychopath. If they were trained and resourced by US interests, well... who needs to know about that?
