In Greg Laurie's book, Lennon, Dylan, Alice, and Jesus: The Spiritual Biography of Rock and Roll: he relates a second hand account of John and Yoko bicycling through a part of Japan where she grew up, was recognized by some people they knew, so she and John turned around and came back to talk to them. Apparently one of them turned out to be a Catholic nun (or maybe a missionary ?) if I recall the anecdote correctly, and she began to take John to task for some of his more infamous comments, especially the one about the Beatles popularity that got him in so much hot water. He reported told them he never should have said it, acted embarrassed, and passed it off with a comment about how when they were in the midst of all that craziness they often said things when talking to reporters and interviewers just to be outrageous. He said it was a ridiculous thing to say.
One can only hope the story is accurate. Of the four, his was the most dysfunctional and troubled life growing up, and as the oldest he no doubt took himself too seriously with the wealth, fame and notoriety that was thrust on them in that time. That he and McCartney produced some enduring works of music and had enormous impacts on the world's culture is indisputable. His death was not 'deserved' any more than any of the rest of us, and only facilitated by the lunacy of a sick mind.
