I'm the villain but i'm not wrong

In a medieval fantasy world ruled by magic, swords, and a mysterious System, absolute power has always belonged to those who possess overwhelming strength. The strong rule. The weak submit. And villains are always destined to lose. Until a strange soul awakens inside the corpse of Theodore Van Astrea—the legitimate heir of a powerful noble family who should have been dead. He is supposed to be nothing more than a minor villain destined to disappear from history. But the person who now occupies Theodore's body has a different idea. He doesn't seek overwhelming physical strength. He doesn't need legendary swordsmanship. Instead, he chooses a path no one believes can exist: Perfect Control. If absolute strength is the ability to destroy anything, then he will create a power where destruction itself becomes meaningless. Using nothing but intelligence, manipulation, deception, and an understanding of human nature, Theodore begins constructing his own game board. Demons make contracts with him and regard him as a companion. Angels praise him as though he were an apostle. Humans, meanwhile, fear and despise him—not because he is the strongest, but because he is simply too clever to be controlled. Yet Theodore has one peculiar dream. He wants to prove that a villain does not necessarily have to stand on the wrong side. Perhaps morality is not as simple as heroes and villains. Perhaps the world has simply never understood the villain's perspective. And so, while everyone else fights on the battlefield with swords and magic, Theodore wages a different kind of war. A war of information. A war of deception. A war where the battlefield is the entire world. This is the story of Theodore Van Astrea—the legitimate heir who should have remained dead, yet returned through the possession of an unknown soul with an absurd dream. A man who refuses to play on someone else's board. Instead, he creates his own.
