There could be a group of 20-30 in a modern illuminati for sure, leaders of their own secret societies - people like bloomberg, rockefellers, cuckerberg, obama, etc.

I think at the highest levels they 1000% believe and serve satan - enacting his plan. I think most freemasons are agnostic larpers (sheep work/recruitment pool) and the better you are at controlling people, the eviler you are and higher you rise in society - the more promotions you get within their clubs.
