I know nearly nothing about this case. Presumably, real police and real forensic scientists will look into her claims, and will find out whether she’s on the level or spouting nonsense.
But yes, for me, her claims of Satanic influence make me think she’s either a nut or a con artist trying to position herself for an insanity plea later.
Would Charles Manson count?
The few people I ever knew who claimed to “worship Satan” were all annoying teenagers trying to shock people.
“But what if they’re true!” in the face of mountains of evidence and testimony that they are not is the hallmark of the Irrational Conspiracy Theorist. We see this over and over in pretty much every sphere of Human activity. People who are so fucking insane, so beyond reason, that they WILL NOT accept that their pet belief is wrong and keep shouting it from the rooftops.
Sadly, every so often completely ignorant people wander into the trap and, for a short time, ask the same stupid questions, which have long since been proven false, but hey, it’s new to them and they don’t know!
I don’t think Manson would count. No clear ties to Satanism. Manson himself was not involved or even present in any of the Tate-LaBianca murders. That set of murders happened in the space of a few days. “Pig” and “War”–words left by the murderers on door and on Leno LaBianca’s stomach are not related to the topic at hand, maybe are loosely related to the “times.” Charles “Tex” Watson, the actual leader of the actual murders had no connections to any of the factors under consideration here.
Wow. And here I thought I was being (relatively) polite.
Respectfully, I do not believe you are succeeding.
Well, I certainly wasn’t aware I had said anything of the sort. I have no idea how your personal faith is at issue here.
All I’m saying is that individual pathology, even to the extent of self-claimed “Satanism,” has almost nothing to do with religion, cults, or spiritual organizations. I am concerned that you have conflated them, and I consider that flawed reasoning.
I do not understand why you feel that I’m attacking your faith. Please help me understand.
When I was preparing to do my Psych rotation in nursing school, I was terrified of the patients. To make matters worse, I was assigned to the Aggressive Men’s Floor of a run down scary hospital in one of the worst west side neighborhoods in Chicago, known for rampant crime and drug abuse (the neighborhood, not the hospital).
When I was done with the rotation, I had a new appreciation for the plight of the homeless-and-maybe-a-little-mentally-off men in my city…and I was terrified of the Psych nurses.
This thread is reminding me why.
Okay, mark me down in support and appreciation for Whynot, too. 
Doesn’t it pretty much take a Nurse Ratched to handle 'em?
What does Richard Ramirez have to do with ritual murder?
Nah. Most of 'em (the patients) were kittens who wanted a warm bed and three meals during a Chicago winter. They knew that if they walked into the ER when their SSDI check ran out and said they were hearing the voices again, they’d get a bed and fed. Most had substance abuse problems that were far more troublesome than their mental illness diagnoses. (Always plural, often contradictory.) There were a few who were legitimately mentally ill and symptomatic, but they were easily handled even by me as a student, with the techniques we were taught - none of which involved being a bitch.
It wasn’t overbearingness or meanness in the nurses that I saw at all. It was apathy, laziness, jaded cynicism and general stupidity. I wasn’t so much terrified of what they’d do or say to me; I was terrified that I would become like them.
Please note: I just referred to an overabundance of jaded cynicism. I mean…really. That should tell you something. 
What does it matter how jaded, etc., they are? The way you tell it, they’re not really psych nurses anyway, they’re just hotel staff.
Mostly. But not entirely. As I said, there were some legitimately mentally ill patients with acute symptoms. It was watching how they handled - or rather didn’t handle - those exceptions that I found unacceptable and drove me out of psych nursing as a career choice. It was all sedate and isolate and ignore. The classes and groups on the schedule almost never happened, no one was interested in actually helping those patients to heal. While most of them were indeed overpriced hotel patrons, there were others who were not - but no one was interested in differentiating the two or treating the patients as patients.
Same thing I’m reading here. Her patient came in during “Satanic holidays,” because she was so upset that a hospital was the only place she felt safe, and she sat alone in her room. No interventions to draw her out, to help her learn how to deal with her anxiety, to get her functional enough so that she didn’t need to be hospitalized 8 times a year. This woman needed a nurse, and she got a hotel staff - a hotel staff who said nasty things about her in the break room while she sat quietly alone in her room in terror.
I’ve known a few people with dissociative identity disorder. They have indeed suffered from various forms of abuse as children.
I’ve known mentally ill folks who believe all kinds of things that aren’t true. I’ve got a friend who believes he’s a werewolf. Given that there is no evidence that SRA exists, I tend not to credit the testimony of these people. That doesn’t mean that they’re being deceptive or that they weren’t abused, it just means that there weren’t the victims of SRA,
He has to do with multiple murders at a young age that he personally attributed to his relationship to Satan. See Wiki.
I was thinking about Richard Chase, too. I’ll look him up now and post if it’s relevant.
I knew a guy who was convinced he was a Dragon. The worst, most unforgivable thing I said to him was to tell him that he was Human. The man died in his mid 30’s because he ignored serious medical issues that he was convinced were signs that he was physically transforming.
And he was! 
Well, yeah, sort of. Transforming into a dead man.
Seriously, how many times do you have to black out (not drug or alcohol induced), then wake up on the floor hours later, sometimes coughing up blood, with temporary amnesia, when you admit that you have astronomically high blood pressure, and not recognize this as a serious fucking medical issue that requires immediate attention and you’re lucky you actually woke up from it at all!?!
Until the day he didn’t wake up from it.
The wolfman has accepted that he can’t convince me he’s a werewolf and I’ve accepted that I can’t convince him he’s human.
I still work on changing some of his wolfish behaviors (like barking as a greeting). They concern me because they lead to his being unhappy. People see him as a dangerous freak and so never get to know the sweet, patient, giving, brilliant person he really is.
Richard Chase seems to be loosely connected to Satanism by various media sources. Though nothing I’ve seen convinces me, he was a young ritualistic killer who took out multiple victims in a very short amount of time. His obviously disturbed mental condition looks to be the biggest factor in his “career,” and not affiliation with Satanists or whatever.
The “Beasts of Satan” were a young group of death metal fans in Italy who killed multiple victims over six years. Some ritualistic acts are attributed to them and they claimed a connection with Satanism.
Details in wiki and many other sources.
I’m looking at these crimes because they show evidence that it is not unheard of for a person Miranda Barbour’s age to have committed ritualized multiple murder. YMMV
Sure, but his personal psychosis was not associated with Satanism or a cult.
