The villain's way to tame the protagonist

Ansir Hydra, the greatest villain of the empire, saw a hopeless, predetermined future after devouring a strange being called a traverser.
The war god who crushed the army, the saint who bore the great sin, the sorcerer who saw the truth, the brave man who was most benevolent and kind... they would destroy the family, destroy the empire, and destroy everything he had.
When Ansel truly realized the cruelty and weight of fate, he became enlightened.
"If the empire needs to change, then there is no need for the so-called protagonist. I, who have this knowledge, can do better."
"And you, the destined ones favored by the world..."
"If fate has decreed that you cannot be destroyed, then I can only let you stay by my side... and fall to the end of the abyss."

In short, this is a story about a bad guy who rebels against fate, tries hard to tame the children of fate and the darlings of heaven, and in the process revolutionizes the world.
