So I came across this quora question recently that said, "Who are some people historically seen as heroes who were horrible people in reality?". One person answered, "John Lennon, one of the finest songwriters of the 20th century and wrote the book on modern rock stars. He's often seen as a man of peace and certainly used his position to promote unity, and equality, writing songs about female subjection and refusing to play gigs with a colour bar. But in his private life he was a bully, a wife beater, viciously unpleasant to and about the other Beatles and Epstein and seemingly incapable of keeping a faithful relationship. I'm a great fan of his work but not a nice human."
While this is a bit harsh, I think it is quite true that John could be unpleasant to others and he wasn't at all faithful to Cynthia (in fact he didn't treat her or Julian as he should have), but do you think he was a wife beater? I remember he did hit Cynthia once while they were dated (he was jealous of her speaking/supposedly flirting with Stuart Sutcliffe, if I remember correctly), but according to Cynthia it never happened again. Do you remember any other occasions?
