Villain: A Person Who Occasionally Goes Crazy!

What would a mental patient do after transmigrating into a fantasy world and becoming the villainous Holy Son?

Naturally, he'd wildly proclaim to those self-righteous protagonists who think the world revolves around them:

"Hahahahahaha..."

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

"Their requiem should ring out in my name!"

"I'll settle your score myself!"

"You think you can kill me?!"

"Feel my pain!"

"Ha↘ha↘ha↘ha→ha↗"

Or perhaps he'd clutch a long saber and swing it wildly, howling like a mad dog:

"Ah! Fight!"

"Or you'll be forgotten!"

"Protagonists, you deserve to die!"

"Come on! I could kill you a thousand times and it still wouldn't be enough!!!"

"Hack them apart! Cut them open!
