That does not excuse sloppy prosecution in the form of blatantly submitting facts not in evidence:
Prosecutor Lily Stroud said the evidence was meant to show that Davis had chosen to affiliate with an organization that condones and encourages human sacrifice and other illegal acts.
In that context, ones belief system is relevant just as it would be if the convicted were a Muslim or a Branch Davidian.
If it were shown that he committed this or other crimes in the name of or even simply because of his religious beliefs then I would agree. That isn't the case here and that is the issue I have with it. As an example, I see a world of difference between a guy that happens to be Muslim that shoots a bunch of people while robbing a bank and a Muslim jihadist that blows up the exact same group of people at the same bank in Allah's name. In the first religion is not a factor at all. In the other it is extremely relevant.
The prosecution did a disservice to the people by cheapening the case with this puffery. Make no mistake, I don't think this lowlife deserves a free redo, but an idiot prosecutor gave it to him on a silver platter. That's all I'm saying.
It would seem to me that someone who is a "Satanist" is someone who already had come to the conclusion that they belong in hell. Square peg in a square hole.
