I think she assumed that her mom didn't use the powers in order to not force the spirits to commit murder. Admittedly I didn't question it much because the woman was fridged decades ago, who knows if that's accurate ? But it does seem odd that someone marrying a presumed enemy to help kill him would have such a boundary.
I'm sorry but that battle was so disappointing.
I know it's not over, but after all the build up and chapters of practicing using her powers.
No one thought to ask, 'Hmm I wonder why the other person who had these powers lost and was murdered?!
