Out of all masonic secret societies that worship Satan is the Illuminati the most demonic of them all by offering blood sacrifices to Bahomet or is the Illuminati just another conspiracy theory?

The masons do not worship satan. While they maintain their secretes, enough of them have died that their books are available in used book stores. Anyone can read their dull books and find out about their dull doctrines.

The illuminati attempted to join the masons in Germany but the masons refused to admit them. The two are separate groups.

There never was a unified group under one leader with one doctrine called the illuminati. There were groups with somewhat similar doctrines placed under the heading of illuminati. Secret groups lend themselves to conspiracy theories.
