All The Grey in Between

"To expel a demon, you become a demon," Lilith says, eyes looking off to a distance too far for me to see. "In order to get what we want, we would do anything-be anything-just to see that wish-upon-a-star of ours to become reality." She looks at me, eyes filled with a feeling I've never seen her express.
Regret.
"Listen here, child," Lilith says, her tone in warning. "If there's a will, there's a way. You don't realize it now but our wants are stronger than our morality. You either choose morals or desires, virtues or sins. You can never have both, not in an imperfect world like this. So what is it you choose? Angel or demon? Heaven or hell?"
I look at her. "If heaven is being trapped in a convent," I say. "Then I'd rather perish in hell."
Her lips curl into a smile but her eyes look away.
"If that's gonna be your decision," she says, "then you better not have any regrets."

How far will one go to expel a parasitic demon?
Will you go as far as to kill seven virtuous people?
Or will you only let the demon consume you and become a demon yourself...
