Unfortunately, not all placements turn out to be success stories, and I don't think PP has anything to do with a good person taking in a desperate soul.
Parelli hasn't done anything in this case, if he had, there would be a rescue foundation that he invested his training fees into, which I don't think there is. I'm sorry, but I just don't see putting Parelli on a pedestal as something beneficial. That stuff is basic common sense anyway, he just had the smarts to make it profitable, for him.
I truly hope this story has a good outcome, I'm just trying to be realistic.
