It's cool to celebrate Lennon the great artist. But, like most artists and most geniuses, didn't Lennon once say "Genius is pain", he had some very human flaws. In my view, Lennon the artist was amazing. Lennon the person - vicious, cruel, and almost toxic. The man he sang "All u need is love" was a cruel and despicable family man who showered all of his love on one son and ignore the other one. The kind of guy who when dealing with his best friend (Paul) was a jealous, insecure, swine. Rather than be protective of his friend or even supportive, instead, Lennon the vicious was a cruel and manipulative back-stabber who ran to the press with every single silly and hurtful kernel of half-truths and distorted lies. Celebrate the artist - absolutely. His greatness was beyond reproach. But, curse the man and his contradictions and his ability to be vicious and cruel to the people who was supposed to love. "All u need is love" indeed but be cruel and vicious to your friends and family.
