Problem: God did not create everything to be perfect, only God is perfect.

God gave man free will and Satan is used to test man. God does not want us to fail but if he doesn't test us then how can we suceed?

As to saying God doesn't have a will, well he does becuase in the bible he makes decisions.

While I appreciate that you are well read I don't think that abstact philosophy applies. We are talking about religions. One, Christianity and the second, Satanism. Satanism is directly antagonistic to Christianity and as such can been seen as a work of Satan, not because Satan is evil but because turning away from Satanism would be turning to Christianity and so to God. The reverse is also true, which is why I say there's no real difference between devil worship and LeVay's Satanism.
