Having experience with this, as some of you may know, yes she should be held accountable.

Those accusations hurt my dad to the point he was drinking himself to death. He was able to pull himself out of it successfully. It also ruins the relationship between children and parent.

While she may believe the accusations and truly thinks abuse happened, she needs to be institutionalised, and held accountable for her accusations. They are serious crimes to accuse someone of, and despite no evidence to suggest the accused did anything at al, it will still utterly ruin their lives. With the internet these days, even the innocent will have an extremely difficult time with their future jobs and relationships. They will be seen as untrustworthy at the very least.

However, with all that said, there is a very real chance that none of that will help her. It's still ultimately up to her to recognise her disordered thoughts and understand that she needs serious mental health help. Schizophrenia is insidious, especially in women, and just alters their reality to the point that it is almost impossible for outsiders (be it family or partners) to help, especially if it's paranoid schizophrenia or religious-based (as is the case with my mum).

I have sympathy for the woman, but it just isn't right to go around accusing everyone of doing that heinous shite.

I feel for the children and father in this, and the people who have lost their jobs because of this.
