Not sure he was ever sane or normal. I was watching Jon Stewart last night and he recounted a story from back in 2019 or whenever where he and a handful of first responders were going around and meeting US senators and reps to help support potential legislation to get 9/11 first responders treatment for cancer and other toxic cleanup ailments they had. Stewart said they met with Lee and the first responders took turns telling their stories. A police officer recounted his emotional experience of being in one of the towers that collapsed. When he was done telling story, Lee had this smile/grin on his face and said, “Man, I bet you’ve got a lot of stories.” Stewart said they left the meeting and as soon as they walked out, they all looked at each other and said, “What the fuck was that?” He said it was the only meeting of many they had where they had that experience. Needless to say, Stewart is no fan of Lee.
