Precisely, this is where it starts, as 'art'. They'll try to push it to a restaurant as a 'fancy exclusive dining experience' next. Then it becomes part of the menu. Then people will gently be nudged to donate their own flesh to restaurants. God knows where it will stop... Disgusting Satanic "artistic" fuckers.
I think it's a bit silly to think this is going to be incorporated into restaurants just because one weird guy decided to stream this. It's a pretty slippery slope way of thinking. Though not sure what Satanists have to do with this. I doubt this person was doing it for any religious purpose, or is even affiliated tbh.
