Is there any line that can't be crossed when it comes to love?

"In a world of deception, my obsession with you is the only truth I have left."

"I'll strip away every delusion you live in, until all that remains is the raw truth—I'll never be yours."

"I've suppressed my selfish desires for so long, yet with you, I'm tempted to sin once again."

"The longer I look at you, the more I believe that getting blood on my hands was worth it."

Do demons want love or power?

"I despise everything you are and everything you harbor within you."

"Yet I still don't see you pushing me away."

"How can you trust me? I'm a menace!"

"Because before, I always believed in what I could see, but now, I believe in what I can feel."

"Just like you, I'd do anything for the one that I love, even if it means going against the strongest entity of the universe."

"Why? What will you do? Kill me?"

"Kill you? No, I'll skin you alive and leave you to burn in the fire...just for the hell of it."

"Even villains have their own demons; who do you think will be yours?"

"What are you so afraid of?! If you love me, then let go of your inner turmoil and give into me wholeheartedly!"

"I'm nothing but a monster in disguise, and if  I end up hurting you, I don't think the world will ever have peace again."

 "One day the tables will turn. And your head will be under my foot."

"I'll ruin each one of you. Piece. By. Piece, from the silence of the shadows. And none of you will even see me coming."
