A decision made to stop a fear will build that fear into everything you make afterward.
Fear is an efficient designer of vehicles, because a frightened man will take any solution that reliably removes the threat, and gold calves remove his. The need underneath is certainty: hold the throne, hold the people, make devotion local enough that loyalty never has to travel anywhere he cannot see it.
It works, and that is the danger. A strategy that delivers certainty gets built into an institution, and what one king settled in a single frightened hour becomes the worship his nation is handed for generations. A man who takes counsel from his fear rather than from what he was given keeps the thing he was protecting and loses everyone who comes after him.
