As a devotee and student of Crowley for many years, let me give a riposte to your finely written essay.
"Do What Thou Wilt shall be the whole of the Law" is but the first line, if people stop there, they deserve where they end up. The next line is "Love Is the Law". Go back up, rearrange the first line, and you get, Do What Thou Wilt Is the whole of Love".
Followed by the third line and final line of the message from Aiwass, "Love under Will."
Love under will is a duality, so the best source for that would be Crowley's Book of Thoth, on the Tarot. Look at the deuces. The two of wands act as a barrier, the two of swords, cancel each other out, the two of pentacles, balance each other, it is only in the two of cups that the image is presented. One cup flowing up to another above it, from which water falls down to fill the first, which then rises to fill the other. Love under Will.
If one is doing something, it should be one's will, if not why is one doing it? One's will should be what one loves, hence love generates the will and the will in turn nourishes its love. Will can never generate love, therein lies the problem for those who use love potions and such.
As for Crowley being a satanist, if you read Magick in Theory and Practice, the book makes very clear, that Satanism is a mistake, for Satan involves a duality and all God's are unities. Why settle for a second rate position, when Godhead is available?
Crowley wanted to be left alone to pursue his studies, one of the best ways is to make such a name for one's self that all but the ardent will do as he asked, stay away. The other is to be under the radar, just a face in the crowd, Crowley could not do that, so he did the former.
Just some thoughts, any ripostes eagerly sought.
