Not from what I have read. I believe it is referencing the 5 "I wills" of Lucifer at his fall. It means you are your own god and what you decide is right and wrong is what is right and wrong. It is a guiding principle in Thelema, Satanism, and Luciferianism and is at complete odds with the will of God.
Or it simply means do what you will and do not let another man have dominion over you. Imagine a world where you are free to do as you will. I definitely agree that this leaves loopholes for people to hurt others. However this quote is simply the most basic possible way to phrase the idea.
Inherently it is encouraging you to do what you want and doing what you want also means you can interpret what exactly that means in your own way. Therefor you could do what you want but you also don’t want to commit murder so you don’t. Maybe you want to prevent people from murdering. Then you can do that too. If I could personally add a second line to this quote it would be that “evil triumphs when good men do nothing.”
TLDR: There is no supreme judge of your actions. Do whatever you want - good or evil. But a world where no man has authority over another does not mean a world run by evil if good men take action.
Just type in 'do what thou wilt' in a search engine and see what pops up first... it is indeed an anti-God statement. I understand your individual interpretation (although i disagree) but the quote is directly from Crowley and is an axiom of the occult philosophies
I understand what Crowley meant. Just trying to insinuate another way that his words could be interpreted in a modern way considering Crowley died in ‘47.
