In fairness to the first Thelemite, Francois Rabelais, it should be noted that the origin of "Do What Thou Wilt" and the "Law of Thelema" was benign: http://www.thelemapedia.org/index.php/Rabelais
They were transformed by Crowley, and then Hubbard.
From Aleister Crowley's 'The Book of the Law':
"We have nothing with the outcast and the unfit; let them die in their misery. For they feel not. Compassion is the vice of Kings: stamp down the wretched and the weak: this is the law of the strong: this is our law and the joy of the world.
"...I am the snake that giveth knowledge and delight, and stir the hearts of men with drunkenness. To worship me take wine and strange drugs. They shall not harm ye at all. It is a lie, this folly against self...
"...The Kings of Earth shall be the Kings forever: the slaves shall serve.
"Them that seek to entrap thee, to overthrow thee, them attack without pity or quarter; and destroy them utterly."
The 'Law of Thelema' is "Do What Thou Wilt."
From one of Jack Parsons' letters to Aleister Crowley, re. Hubbard: "He [Hubbard] is the most Thelemic person I have ever met ..."
And from Jack Parsons, Hubbard's Magickal partner for a time in 1946. Parsons wrote this poem, which appeared in 1943, in the 'Oriflamme' Journal of the O.T.O:
"I hight Don Quixote, I live on Peyote, Marijuana,
"Morphine and Cocaine,
"I never know sadness, but only a madness,
"That burns in the heart and the brain.
"I see each charwoman, ecstatic, inhuman, angelic, demonic, divine.
"Each wagon a dragon, each beer mug a flagon
"That burns with ambrosial wine."
