you sit at home you're hosting a party and currently you're cooking. Within you there is an evil demon that is constantly telling you to do horridly evil things most would call these impulses but the advice from the demon was much much worse than any impulse. As you cook the demon speaks in your head

"You have a knife right next to you and 3 guests are already here... why not test the sharpness of the blade on.. their flesh? Do well, and I'll reward you. By making you mine~"
