Why John Lennon? Didn’t he beat his wife?

Yes, he absolutely did. I don’t want to speak ill of the dead, but he himself would be the first to admit that he was angry and violence prone. He often confessed to interviewers that he could be quite mean to people. Some have theorized that it had to do with his mother being killed by a drunk driver when he was a teenager. Listen to the poignant, tear-jerking Beatles song Julia.
