I'm not really worried about Kim wanting to launch a first strike when he has a solid grasp on his regime. I could see a scenario where he is petty and childish and where a coup is launched, he is about to lose control and makes a decision that amounts to "if I can't run this country, then noone can". He does seem to genuinely dislike the United States, so would be a two birds with one stone decision. I don't know how likely it is for that to happen or whether or not he cares about his countrymen. The purges that he ran to consolidate power early on make it seem like he is not averse to violence.
