Others...aren't. There are plenty of brutes and despots, incompetents and grifters, villains and bumblers.
One of the notable Biblical stories of failed leadership is that of Rehoboam, the son of Solomon, the king who broke the people of Israel in two.
Under Solomon, there were tensions between the northern tribes and the southern tribes, tensions that had been carefully managed. But where Solomon used a balance of force and wisdom, his son lacked any and all capacity for diplomacy. The leaders of the northern tribes came to him, and asked that some of the pressures of punitive laws, predatory taxation, and oppression be removed.
The advisors who had served the Solomonic court told Rehoboam that he should show mercy, that he should be gracious, and thus earn the respect and loyalty of the north.
But Rehoboam was a fool, the spoiled child of wealth. Instead of making peace, he listened to his own ego, and to his hangers-on and sycophants. "Double down," they said. "Show them who's boss," they said.
"Tell 'em your little finger is thicker than your father's loin."
That's "loins." Ahem.
Anyhoo, that's exactly what Rehoboam did. He doubled down. He bullied and provoked and threatened. The northern tribes, led by Jeroboam, son of Nabat, rose up in revolt, and the young nation fell to ruin.
Rehoboam destroyed the Davidic reign, which would make him sort of an anti-messiah.
As it so happens, Rehoboam's name means "the enlarged people" in Hebrew. Or, equally...if more pointedly but fairly translated: "The People Made Great."
I mean, it's all there in the Bible. Straight up.
Those who don't know scripture are doomed to repeat it, eh?
