Lennon was an ex-Satanist at the end, I'd say. He takes a huge dump on them in the song "Free Da People" calling them out by name ("666"). "Working Class Hero", too. In fact, almost all of John Lennon's songs after Magical Mystery Tour (mystery school initiation) could be summed up as "This sucks. I feel guilty. I wish I had never done this. I hate myself. I even hate my rock and roll." Paul was the irredeemable one.
