Lucifer Morningstar: There was this, uh, soul that I used to torture back in Hell. And like a good masochist, he’d call the shots. “Burn me.” “Freeze me.” “Hurt me.” So, I did. And this went on for centuries until one day, for some reason, he missed his daily punishment. And when I returned… he was crying. “Please, my king,” he said. “Don’t ever forget me again. I promise I’ll be good.” It was then that I realized he was so full of self-loathing, void of any self-respect, that no matter the depth of my cruelty, whatever miniscule attention I paid… gave meaning to his… pointless existence.

Amenadiel: Why are you telling me this?

Lucifer Morningstar: Because he reminds me of you. And you think I’ve changed? You… the former angel, powerless and pathetic, a disgraced failure with no better way to spend your days than yipping at my heels for scraps to remind you of a time of when you once mattered.
