Villain: The Protagonist? Blood's Flowing, Leave No One Alive!

What would a mentally ill man do after transmigrating to a fantasy world and becoming the villainous Holy Son?

Naturally, he would face those self-important, self-centered protagonists and loudly proclaim:

"Hahahahahaha..."

"Their screams will be like the faint chirping of insects at dusk!"

"Their elegies should sing my name!"

"I'll be the one to settle your debts!"

"You think you can kill me!!!"

"Feel my pain!"

"Ha, ha, ha, ha, ha!"

Or perhaps, gripping a long blade and swinging it wildly, he would roar like a mad dog:

"Ah! Battle!"

"Or you'll be forgotten!"

"Protagonists, you deserve to die!"

"Come on! Even killing you a thousand times wouldn't be enough!!!"

"Chop them down! Cut them apart!
