Funnily enough, that may have actually kind-of happened to Fred Phelps. He didn't have a stroke AFAIK, but some of his family remembers claim that not long before he died and when he was kind of losing his marbles he'd go over to the building owned by protestors across the street and chat with them, and said they were good people. He was excommunicated from the church right before he died so there might be something to it lol.
