to be fair, the reason the wytch is holding you is to teach you a lesson, which she has mentioned several times, and i just view that changing you is just part of it, so even if you do complete her chores, its obvious the only way to be certain you aren't just trying to fake having a change of heart is to change you anyways.I get what you mean, but it does make sense story-wise when you think about it this way. though i guess one special ending could have been where the player did so well that the wytch does decide to let them go without changing them at all, but if i were in her shoes, not sure i would be capable of doing that either. if someone tries to kill you, i doubt you would let them off that easily (i know i wouldn't).
