This is what a renowned Freud researcher, Peter Joffre Swales (1948-2022), had to say about Freud:
Alluding to his own character's similarity to Freud's - always manipulating, never really being able to be forthright - Swales explained that in taking on Freud I was taking on the monster that existed in myself.
Freud was, indeed, as close to a monster as it is at all possible.
When I read The Interpretation of Dreams, I recognized the web of deception he was weaving, Swales wrote.
The way Freud’s mind worked was totally familiar to me. I knew the games he was playing, I was totally versed in his manipulative logic and rhetoric. And I knew there was a man hiding behind a mask - it didn’t add up otherwise. One can only agree.
Freud knew how to manipulate people, both in real life and in his writings. As Swales rightly pointed out, a man cannot write about sexuality the way Freud does and be so dispassionate toward it.
Without a doubt, until this day, Freud the pervert, and criminal, has been successfully wearing the mask of a saint,
Most people could never understand Freud,  Freud is much too complex, devious, sinister. Ain't that the truth?
Notably, Swales claimed that he was, the only person who has ever really understood Freud. Maybe not, but, once you have perused this site, you can judge for yourself.
This is how Swales explained his worldview: My starting point is that all people are devious and sinister, that they’re shits. For me, the world is full of shit, so I'm not disappointed. *
He may have had a valid point, most certainly, regarding Freud.

Sigmund Freud (1856-1939) was the inventor of the, by now, largely defunct, pseudo-science of psychoanalysis, reflecting his bizarre personality projected on humankind. This is what he wrote about his motivation for becoming a doctor, At the age of eight he was impressed ... that it was the doctor’s custom to get into bed with his women patients. (1)
The idea worked like a charm. Women came to him, of their own free will, or, even worse, brought to him by their unsuspecting friends, family members, and husbands even.
Freud was not interested in curing people, only in becoming famous and making lots of money. (Sexual exploits were a bonus). He was also enamoured in cocaine, more so than in his fiancé, Martha. In this regard, he was painfully honest in his letter to her of June 12, 1894, stating:

When I’ve thought sufficiently long about you and about cocaine, I think about money and again about money.  (2) As it is obvious, Freud lived for money.
Writing to his lover in Berlin, Wilhelm Fliess, five years later, Freud explained that his patients' money was laughing gas for him. (3)

As it is often emphasised, Freud's bizarre ideas had a deep influence on the thinking of Western societies, the American society, in particular. Considering the degree of Freud's insanity, perversion, and criminality, it is not surprising that our societies look the way they do.
Oddly, while lots of people complain about the current state of affairs, not many ask of what lies behind it. And part of the answer is obvious: the Freudian madness.

Bringing the plague

That Freud realised that he was a merchant in perversion and debauchery is apparent from his statement to his follower and crown prince, Jung, when they were arriving in New York, as recounted by the French psychoanalyst, Jacques Lacan:
Thus Freud's words to Jung - I have it from Jung's own mouth - when, on an invitation from Clark University [in 1909], they arrived in New York harbor and caught their first glimpse of the famous statue illuminating the universe, 'They don't realize we're bringing them the plague. (1)
Freud wasn't joking. With them, they brought the Viennese plague to the U.S.

Even though most people weren't aware of Freud's true, perverted, and criminal nature, there's been lots of research about the dark side of the psycho-prophet.
Freud .... was not only charged ... with murderous hostility ... he was also described ... as a plagiarist, as tyrannical and intolerant, ... as greedy for money, as hating his Jewish origin, as a corrupter of morality and ethics, ... and as one who created legends about himself.  And most of it, if not all, is true.
Moreover an author openly stated that Freud wanted his pupils to be castrated. (1) (Compare KIlling Tausk page.)
There's no need to "unfairly" charge Freud with murderous hostility. Freud wasn't hiding what he was about: wasn't it Freud who proclaimed his wish to kill his father?

Incestual Freud

Freud also, analyzed one of his daughters, as if this had been an act of incest. (2)
(Analysis of Anna was an example of a metaphorical incest combined with a real one. There were factual cases of incest in the family that also Anna was subjected to.)
Some biographers look on him as the primal father in the primal horde. (1) And they are right.
Freud kept his followers on a short leash. Sometimes if the leash wasn't enough to keep them at bay, Freud had a more lethal means of controlling them,.
The claim that Freud wanted to castrate his disciples - taking into account his bizarre ideas - sounds like something he would enjoy. And, most certainly, the analysis of Anna on the proverbial couch, confessing her obsessive masturbation, and not only, was without a doubt incestual. No wonder, Anna wasn't ever able to free herself from her oppressor.
There's no doubt that Freud was both acting as the father of the primal horde and as a pasha of his bisexual harem.

As Freud pointed out, it is impossible to understand anyone without knowing his sexual constitution.*
Thus, the question of his, and his family's sexuality, from a Freudian point of view, is an important one. As a matter of fact, not only Freud, but also the whole Freud's extended family, as it has been reported, was highly promiscuous.
Already in his teenage years, Freud was promiscuous, having both gay and heterosexual relationships. The true love of his life was his "dearest", doctor Wilhelm Fliess, from Berlin.
* Freud, S. & Zweig, A., The letters of Sigmund Freud and Arnold Zweig, 1970, p. 85. Letter to Arnold Zweig, July 15, 1934.

Freud married, and had six children, some of them, but not all, his own, since Freud was loaning his wife, and possibly the rest of his harem, including his sister-in-law, and his three daughters, to friends and acquaintances.

Freud's hospitality

I am sorry that I can give you no real hospitality, Freud told Jung when he came to Vienna for a visit, I have nothing at home but an elderly wife. (1) A case in point: Martha wasn't always elderly.
Freud didn't care about the societal rules. Already aged 19, like a true psychopath, Freud proclaimed that, a thinking man is his own legislator, confessor, and absolver. (2) This was to be his life's motto.

The Austrian Superman

Freud considered himself a Superman - a concept similar to Hitler's, Übermensch - originating in Nietzsche, thus a person that is his own master. Thus, in his dream book, Freud proclaimed, I was the superman. (3)
Among many others, one of the broken societal rules was the "taboo" of incest that Freud happily breached with his offspring, making at least two of the daughters pregnant. A couple of abortions were performed, leaving one of them unable to conceive.

As he confessed in his letters to Fliess, Freud was mentally ill all of his adult life. Having tried to find out the reason for his lunacy in his past, Freud came up with several bizarre ideas that, over time, he turned into the pseudo-science of psychoanalysis. Thanks to his likewise lunatic followers, in particular Jung, Freud managed to spread his mad ideas all around the world.
It was like an epidemic infecting otherwise highly educated people, who suddenly lost the capacity for critical thinking. Remarkably, some still insist that Freud was a genius.
Not all were blind, though. This is how Albert Einstein, writing to his son in 1935, and referring to Freud's crazy house of treatment, stated his position, I am almost positive that the thing with the Viennese doctor is a simple swindle. *
Without a doubt, Freud was one of the most famous and infamous people of the 20th century. His "controversial", or, rather, a madman's, vision of the human character a reflection of his abnormal personality.
In his writings, Freud promoted perversions and sexuality, as a panacea for all human ills. He knew, of course, that what he was promoting was degeneracy rather than a cure for mental illness telling his disciple,  
Insanely, projecting his murderous and incestuous urges on humanity in general, Freud claimed that every boy, like Freud, wants to kill his father and have sex with his mother.
Freud's main claim to greatness was the notion of the unconscious mind that, reacting to our earliest experiences, controls our actions. The notion wasn't even his own.
*Bachner, Michael, Freud’s a fraud? 110 unpublished Einstein documents unveiled by Hebrew U, The Times of Israel, March 6, 2019.

Freud considered himself superior to both Nicolaus Copernicus and Charles Darwin, even though his psychoanalytical invention had nothing to do with science but everything with Freud's deranged mind.
But everyone can dream of greatness, and Freud most certainly did, repetitively vying for the prestigious Nobel Prize. He was nominated for the prize several times, but without getting one.

Sick and twisted imagination

Considering Freud's last nomination in 1936, the Nobel Committee, wisely, rejected his candidature for the prize, stating:
Freud appears, more than any of his patients, to be possessed by a sick and twisted imagination, which speaks volumes, since he has an abundance of unusually strange patients.*
One can only agree.
* Svensén, Bo, ed. Nobelpriset i litteratur. Nomineringar och utlåtanden 1901–50, vol. 2, (2001, p. 24).

Remarkably, almost a century later, the infamous couch on which, behind the padded door, Freud sexually treated his patients is proudly on display in the Freud Museum in London.

"Will you walk into my parlour?" said the spider to the fly

This is what, according to one of his associates. Freud had to say about the couch's intended use:
We once visited the newly furnished consultation room of one of our colleagues. Freud, pointing to the very broad couch, said smilingly to me, That is rather for group analysis. (1)
As anyone realises, Freud needed a suitable piece of furniture for his hard work. It was to be the couch.  So what was Freud's business idea? To cure sexually abstinent patients ... Freud could give his patients sexual satisfaction. (2)
And he most certainly did, getting well paid for his endeavours. I guess, the name for a man providing this kind of service is gigolo

Disgusting fellow

Not all of his patients were interested in submitting themselves to the Freudian cure on the couch.
As one of the patients recalled, Freud, was a disgusting fellow. ... you were held to be half-crazy if you went to Dr. Freud. (3)

(3) Scammell, Michael, Koestler: The Literary and Political Odyssey of a Twentreth-Century Skeptic, (2011).

This is the picture that illustrates Freud's sexual theories. As it is apparent, the drawing by Freud's hand - pun intended - is a primitive depiction of the male sexual organ in the state of flaccidity. Freud himself suffered from partial impotence, among others, due to his cocaine addiction.
This is how, based on the pictorial representation of his phallus, Freud, the thinker, explained the sexual “anaesthesia” (impotence) of a male (himself).
One can only feel sorry for his unsatisfied harem.

Freud's psychological impotence

As Freud explained, We cultured people are all a little disposed to psychological impotence.*
At the time, Freud was 51, and already having severe problems with his erection. This is how Freud explained this problem:
The terminal organ is insufficiently charged and in consequence the discharge when copulation takes place is slight and V very small. Here we have the cause of frigidity.**

Freudian mumbo jumbo

Don't be fooled by the pseudo-scientific mumbo jumbo. This is what Freud is saying: if the penis is not stiff (charged) enough, and the amount of ejaculated sperm (discharge) during sex is small, then there's a problem.
What the small “V” stands for is not hard to guess (vagina).  Interestingly, in Freud's drawing, the Freudian terminal organ is bent. A curved penis is typical of Peyronie’s Disease.
Oddly - with this type of bizarrely primitive ideas -  somehow, Fred was (and sometimes still is) hailed as a genius.
