Wow, free will/determinism & order/chaos are huge
topics that we are not going to be able to resolve here...not by a long shot!
In fact, I don't even think those topics are appropriate for this particular forum which is simply dedicated to:
Examples of the Satanic Philosophy, Articles, Essays, News Clippings, Videos, Interviews, etc.
What I will say, though, is that Satanists tend to not spend too much time speculating on such issues (theories on which cannot really be proven). Satanists focus on what is practical and useful!
