Strange, i talked with her almost everytime i could but she's the only one not present at the love shack invite screen.
I don't know if and when consequences will be added for that (maybe relation loss with your maids, or some dialog changing) but so far, there's no reward for this except being better than many other Masters would in the same situation.
IIRC destroying it will give you some quick headstone materials, but the psychic backlash will kill all the maids & butlers presents, + freeing the merchant from the accord at the nearby town.
Fixing it will ease their pain and allow them to regain consciousness.
I never tried to destroy it (wouldn't feel "right", especially after what Master lived through) and always tried to help them.
And spoiler for later on :
