Very little of any of this is satanic, the first half of the thread is just either neo-pagan imagery or just edits of people with flowers in them. Christians like to say that any religion that isn't Christian is satanic, which is also where a lot of satanic imagery comes from because of Christians associating non-Christian deities with the boogymen of their religion.
The second half of the thread is all depictions of pedophilia and ritual sexual abuse, which is not at all linked to Satanism but rather to a new, undefined wave of western occultism prevalent among the elite. Modern Satanic religions(The Church of Satan, The Satanic Temple, etc.) have rules among their central tenets that specifically forbid any kind of sexual abuse, to minors or otherwise.
If you want actual explaination or analysis of satanism and the inspiration behind its imagery, I would suggest reading the Wikipedia pages for Satanism(theistic and atheistic), Demonology, Thelema, the key of Solomon, Dante's inferno, Wicca, and European paganism. Even if you're a staunch atheist or even devout Christian, it's a very interesting rabbit hole of history and culture that shows how differently the world looked at religion before the abrahamic religions became the dominant theology.
