The villain's way of taming the protagonist

Anser Hydera, the biggest villain in the empire, saw a hopeless and established future after devouring the strange existence called the traverser.
The valkyrie who crushed all armies, the saints who have committed great crimes, the warlocks who know the truth, the brave men who are most benevolent...they will destroy the family, the empire, and everything he owns.
When Anser truly recognized the cruelty and weight of fate, he came to his senses.
"If the empire needs to change, then there is no need for a so-called protagonist. With this knowledge, I can do better."
"And all of you who are favored by the world..."
"If it is fate 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, in order to rebel against fate, tames the children of destiny and the girls of heaven with heart, and revolutionizes the world by the way.
