I am not talking about the new age satanic church or anything like that but of cults with ritual abuse and what not.
Not really. Anton LaVey's Church of Satan is atheistic and believes in materialism and retribution in the styles of Nietsche and Ayn Rand. The few theistic Satan worshippers incorporated either Wiccan ideas or the idea of Satan as a benelovent Lucifer. Myths of ritualistic Satanic killings and Satanism in the Freemasons have been discredited. The only "evil devil" worship seems to be individualisic in nature or loosely affiliated on the internet.
