Hero of Competence

Five men met at a crossroads and one slew the other four. That was common enough, but strangely, he said this.
"Each of those men committed a crime. The first was weakness, the second incapability, the third powerlessness, and the fourth clumsiness. Until now you have regarded trivialities as sins and ignored the true transgressions. Correct your behavior."
Everyone who heard the story reconsidered his way of life, not wishing to be killed by a powerful warrior. In the end, the people as a whole concluded they ought to hunt him down and kill him rather than be found wanting by his standards instead of their own.
They confronted the man, but he simply laughed. "Don't you know? The men I killed are the north, the south, the east, and the west, for everyone in every direction is at fault and will die someday until you realize your own incompetence are what keep you from immortality. As for me, I don't represent anything. I'm just the first to figure it out."
The people of the world stabbed him for hours without killing him, at the end of which they admitted they were bad. He told them that was the foundation and left. From that day, true sages began to appear in the world.

A Harsh but Deserved Penalty

"Once upon a time, the people were troubled. They all had the same question and no answers. In their confusion they went to the temple and prayed. 'King of the gods, please tell us how we can tell when spring ends and summer begins! We offer you six thousand bulls as sacrifice.'
"The great god heard them. He descended from his palace and said this. 'You don't have nearly enough problems if this is what you're praying for. I've decided you'll all die, most of you within a century of your birth.' And that is how humans became mortal."
"Wait," one of the children objected. "Why do I have to be mortal then? I never bothered any god about anything dumb like that."
"Maybe not, but you did wake me up to bug me about when's the next time we're going to the city," the father said, and that shut the little twerp up. But not for long, and therefore immortality is denied us still.
Moral: Don't pretend you don't know.

Revisiting Old Ideas

Technology has solved problem after problem. It became unexceptional to read about this disease eradicated, that famine averted. The only difficulty, people expected, that could never be solved was achieving perfect government. They held that belief so firmly that nobody noticed when it was.
Join us now as we go behind the scenes to get a glimpse, if we can, of how this little lab ended the scourge of poor road repair, riots, and expensive campaigns all at once. Analysts assure us it's not mind control, but what if they're the ones being controlled? Ha, ha!
Here's Dr. Ermeyer. Give to us straight, Doc. What's the secret?
"Well, you know the old saying about magic and technology? We synthesized a chemical which gives people magic powers. After some trials, one thing led to another, and, well, the government is now run by immortal wizard-kings."
Amazing! What made you think to try that?
"We read a bunch of books with immortal wizard-kings in them. This was usually presented as a suboptimal situation, but quite frankly, none of us saw a good argument why. It seemed like a good arrangement to us. I'll leave it to the rest of you to judge."
There you have it. Magic is back, and it's more helpful, and less fell and dolorous, than ever! With the joys on offer today, our immortal wizard-kings don't need tyranny to have a good time. Even magic has been fixed by technology.

A Question to Diablo Lore Experts

Wouldn't Diablo being immortal cause a lot of problems? Lootwise if nothing else. The plot might be a little unsatisfying as well. There's a reason there isn't a Tuck Everlasting game, and I imagine this is it.
