Undertale spoilers (and Charles Williams's _Descent into Hell_)
@kara_dreamer@witches.town Chara even suggests maybe taking a different course of action next time after accusing the player of a "perverted sentimentality" wrt recreating and destroying the world again. Choosing to not give your soul this time results in Chara saying "this is what I was talking about", then reminding you that you already "made your choice long ago". followed by a reset anyway after a jumpscare.
