Why Did I Accidentally Redeem the World-Destroying Villain?

One sentence introduction: What you picked up is not a poor thing, but a crazy person who will destroy the world. [The ultimate pull of redemption and reverse taming] "I once picked up a scarred little demon from the wild swamp. His eyes were beautiful, and he looked at me with a gentle and dependent look. I pity his loneliness and heal his wounds. I love to see him smiling quietly under the pear tree in the temple. I once thought that what I picked up was a poor homeless little one. " No one expected that the goddess's one benevolent thought would bring back not a baby bird in need of shelter, but a world-destroying madman. Pei Xiu, a monster born from the abyss of evil, is an anomaly that cannot be tolerated by heaven. On the day he lost his memory, the goddess above the sky lowered her eyes and became the first color in his black and white world. "Come home with me." The gods took pity on him, brought him from the mud into the temple, gave him a name, and protected him from the wind and rain. He suppressed his anger and pretended to be the gentle person she loved most. He is addicted to this game of redemption, willing to lie at her feet and play the role of a pitiful victim, but every night, he despicably and darkly covets the protagonist of this game—— He wants to monopolize the gods. When the disguise peels off, the fangs finally appear. The devil is ridden with evil desires, but he is willing to take the initiative to put on the rope called "love". The other end of the rope was held in her hand. "Your Highness, I am willing to be your sword. I am willing to be your servant and run as you please." He leaned over and pressed her hand against hers, devoutly like the most loyal believer. "All over the world, ten continents, the demon world, the Netherworld... Whatever you want, I am willing to offer it to you."
