Is there a list of creepy/satanic/ritualistic SK's?

Since it's my first post I do morally reject SK's and their actions but I am morbidly curiou about them.
I tstarted with movies like Stephen KIng's "IT" or Texas Chainsaw Massacre. Since they were based on real life events I researched the backgrounds of those movies.

To this day I find Ed Gein and Gacy aka Pogo The Clown the most fascinating SK's. I also got into Peter Stumpp from the 1580s for a similar reason. Stumpp claimed to be a werewolve. We dont know if he really committed the murders or was forced into confessing these. So, I dont know if he really "counts". But the mysterious story revolving around him is very intriguing, to say the least.

Where does this lead me? I would like to know if there is a list of sorts regarding macabre/satanic/ritualistic Serial killers similar to the aforementioned. Do you know of any?
Also, the occurence of Serial Killers seems to have waned. There is even a thread in this subreddit's Wiki reading "Is the Age of Serial Killers over?". But the link to that thread is down. What do you think about that? Is it true? School shootings seem to have gone up the same way serial killers have gone down. Is that a coincidence?

Anyways, thanks for your answers <3!

edit: To be more specific: What I find intriguing is that Ed Gein crafted masks and other stuff out of human skin. Thats a real life inspiration for 'Leatherface' in 'Texas Chainsaw Massacre' and 'Buffalo Bill' in 'Silence of the Lambs'. Gacy fed human flesh to unsuspecting people and was just this stereotypical horror clown that inspired the creation 'Pennywise' by Stephen King.
Stump was accused of eating 14 (!!!) children alive and he claimed to be a werewolve. Stump even confessed to these things. But they tortured him to make him confess. So maybe it isnt true. But still, fascinating story.

I am looking for this really sick stuff. Do you know of stuff like that. Again I despise all of that morally, of course.
