Unfit king. A ruler can't allow themselves to be 'human'. The fallibility, unpredictability, and emotionality of your average person has no place at the highest seat of power. Only logic, wisdom, and comprehension.
If you make one teensy command or law based on a fit of pique, one moment of passion, thousands or far more can die without anyone able to stop it. Histories can be erased, entire civilizations turn to dust and blow away in the wind. Futures extinguished, lands laid barren, people slaughtered and enslaved, governments toppled, anarchy and tyranny going hand-in-hand like some kind of twisted waltz.
And this guy is so bad off he's tried justifying his rampant stupidity.
