Yes, the while thing is so twisted.
I can't begin to imagine the mindset of wanting to act out, in person, some pretty sick abuse. That was already an uncomfortable and odd thing for me when I was watching it. Not the actual story, but RG himself and his reenactment of some awful and often torturous abuse.
Cathartic? Possibly. But not at all healthy.
Wanting to make something powerful? Successful? Shocking? Yes. Also likely. Pure revenge? Yes, also now seems possible.
But it also brings to mind (for me) the sort of situations whereby some people want to involve others in their fetish, fantasy or other odd behaviour. Similarly, trauma dumping without advance warning on the audience for the first time as has been said. I'd have been very uncomfortable being party to that without warning or consent.
Being applauded for that could be rather addictive, I'd say. Especially in a person who's been subject to abuse and is desperate for validation. It seems to have borne a need for further figurative self flagellation. So called 'Traumedy'
It makes me wonder; if a person was so inclined, they would write a screenplay of a depraved fantasy, star in it themselves, and act it all out publicly as it were. Involving other actors, TV crew and ultimately the viewing public. I'm not saying that's what's happened here, but there's a danger of it.
I also wonder if there were intimacy coaches on the show. Big things have been made of them lately on shows like Sex Education for example. And rightly so. Being involved in the filming of abuse and rape scenes must be quite harrowing.
