I care that they say all the people on the cover of that album "were great influences" on their music. Aleister Crowley was a luciferian black magician who "made Anton Lavey's satanism look like kindergarten recess" according to one author who wrote about what Crowley had said, done, and wrote. Crowley wrote that, "we (meaning his fellow luciferians) should use music to influence young people..." and many wicked, twisted, and evil things. He called himself 'The Great Beast 666' and wasn't shy about it. I doubt that the Beatles were unaware of those facts when they were "inspired" to put him in that group on their album cover.
