there are only 2 possible 'ways of thinking,' it's real simple

either God created everything, or everything created itself

existentialism is one of a myriad of confusing, deceptive labels given to the latter

to those who believe the latter, there is no sin, Do What Thou Wilt is the de facto whole of the law

depp falls into the latter, call him an existentialist, illuminist, satanist, it's all the same
