Kim Jong-un doesn't care about the 'little people' of North Korea any more than Chelsea Clinton 'cares' about coal miners in West Virginia. Neither of them would lift a finger to stop massive starvation...
Hitting dams would cause farmers and innocent families to starve.
Kim Jong-un would retaliate out of pride but all his horrors would stay in place.
Maybe it'd be better to identify every top person in North Korea - political and defense - and kill all of 'em at one time. One full sweep. Some of them will be at 'installations' which makes those deaths a twofer.
Of course before doing this we need to have signed Statements with everyone in the world -(other than Iran and China) that this choice was necessary and we're ALL in on it...
But without electricity, the NorK military grinds to a halt.
Their two primary sources of energy are coal from China, and hydroelectric from their dams. Almost all the artificial light they generate is in Pyongyang. Which is also where most of the coal is burned.

The rest of the North Koreans seldom benefit from electricity or coal for fuel. This is why most of the North has been deforested, as fuel for heat and cooking by the rest of them.
So, you blow up their dams, especially in winter, you mostly hurt their government and military. Only when it is planting season will the rest miss the irrigation for their crops.
