We don't even believe in the existence of Satan or hell. That kind of negative darkness is an invention of Christianity, so please stop lumping Witchcraft together with Satanism! One has absolutely NOTHING to do with the other. 

It crossed my mind how for even as of the 1970's how this episode pushed those societal limits on subject matter in general and also with what you said in regards to your point number 4. I would rate this episode about 3.5 out of 5 hallucinations for good but not great. I like it for some of the points it makes on right and wrong and the results of the choices one makes.
