Omega,
This guy is not a Satanist in the way you might think he is.
He's not a blooddrinking, animal sacrificing satanist.
This guys faith goes a lot deeper than that. His religion goes about human accomplisments on a spiritual level...
Almost sort of buddhist/hindu kind of faith, but aspects of most world religions and ancient religions appear through it.
Research his faith first, and then you'll probaly understand why he chose it.
As far as I am concerned, the name satanism doesn't really apply to this.
Enki&enlil-ist would apply more or something similar.
