John had real bitterness and Jealously and hate toward Paul. Paul never felt anything but deep respect and reverence to John Lennon.
John Lennon was a great musician but he was an evil, selfish, greedy, person. He was the kind of guy who got off on hurting people. He was a lousy father (ask his own son - Julian. How could any man go nearly five years without once seeing his own son!) As Julian said, Lennon preached peace and love to the world but didn't apply it to his own family. Further, Lennon was an uptight, highly paranoid man almost incapable of being a loving and supportive friend. Did he ever seek to patch up his lousy words in 1970 to George Martin, Paul, Ring, and the others. In fact, Lennon destroyed almost every friendship he ever had. His closest friend at the end of his life was the evil and dishonest Eliot Mintz, a man so sleazy and so swarmy, you literally have to bath and apply deodorant after he speaks. Lennon was a sociopath and a man incapable of being a true friend. I love his music to death and i love his talent and his greatness in the Beatles is without question and he and McCartney are both equally talented - but as a person - he is slime!
Paul McCartney doesn't have an evil bone in his body. And never got off on hurting people. McCartney is a true family fan and a guy that you would like as a friend.
Say what you will - Lennon was jealous and envious of McCartney's talent, good lucks, and overall comfort in his own skin. Case closed.
Lennon can never be forgiven for not loving his own son. As his first wife so elqouently said, "He was a right bastard"
