Only a week after Tausk’s death, Freud wrote to his Hungarian follower, Sandor Ferenczi on July 10, 1919, thus a week after Tausk's untimely death:
Tausk shot himself on July 4, a week before the date set for his wedding, leaving behind tender and conciliatory letters. Etiology obscure, probably impotence and the last act of his infantile struggle with the ghost of the father. Despite appreciation of his talent, no real sympathy in me. (2)
Notably, on this occasion, Freud found the reason for Tausk’s suicide obscure. In addition, apparently projecting his own sexual inadequacy, Freud denigrated the dead alleging that Tausk’s motive for the suicide. - was his impotence. This slur was, no doubt, a reflection of Freud’s jealousy of Tausk’s romance with Lou; Freud had a long memory.  Tausk had a short romance with Lou Andreas-Salomé when they met in 1912. At the time of Tausk's death in 1919, though, the erotic tie between Tausk and Lou had been over for five years now.  (3)
And the fact that Freud felt no sympathy for Tausk is a confirmation of his ill-disposed attitude toward the latter. Oddly, in his letter to Ferenczi, Freud made a dating “mistake” claiming that, Tausk shot himself on July 4, even though Tausk died a day earlier.(What this "mistake" may have symbolised is uncertain. What is certain is the fact that Freud never made mistakes of that kind.)
Notably, Freud neglected to mention the fact that, besides shooting himself, Tausk also hanged himself, which couldn’t have been unknown to him.

iI a letter to his Swiss follower, and pastor, Pfister, of July 13, 1919, thus ten days after Tausk's death, Freud was even briefer, writing: Dr. Tausk has committed suicide. He was a highly gifted man, but was a victim of fate, a delayed victim of the war. Did you know him?
Notably, unlike in the letter to Ferenczi, Freud doesn’t mention Tausk’s impotence, or the struggle with the father, as the motives for his alleged suicide. There’s no mention of Tausk’s ill health, and his marriage as contributing factors either. Instead, on this occasion, Freud was speculating that it was the war was to blame for Tausk’s demise. Was it the war, or was it Freud?

In the summer of 1919, in the letter of August 5, thus almost exactly a month after Tausk’s demise, on July 3, 1919, Anna Freud, Freud’s youngest daughter recounted her terrifying night life. Most of the time now, she informed her father in the summer of 1919, something bad happens in my dreams, about killing, shooting or dying. (1)
Without doubt, Anna’s dreams had an uncanny connection to Tausk’s death since, as she informed Freud on July 24, 1919, only three weeks after Tausk’s death, She dreamt that Dr. Tausk's bride had rented an apartment at Berggasse 20, across the street from the Freuds, in order to shoot her father dead with a pistol. (1) Notably, Tausk died by a gunshot.
Could Anna have had this kind of dreams, never having experienced this kind of lethal event of lethal eves?  Or maybe, acting as her father’s assistant, identifying with the aggressor, she had been the witness to Tausk's assassination?
But what was really her dream about? As Freud stated in his Interpretation of Dreams, Dreams … take the liberty of representing any element whatever by its desired opposite. (3)
And, if we apply Freud’s dream interpretation method to Anna’s dream, it clearly reveals that it wasn't Tausk’s bride that wanted to kill Freud, but rather it was Freud that was going to shoot Tausk dead with a pistol.
Could Anna have assisted Freud in his murderous endeavours? The following quote from one of Anna’s poems hints at her possible involvement in Freud’s repeated murders:
And you really believe, because in bright Daylight my appearance has become familiar that you can talk about how I think! Perhaps in the night I am a murderer?  Perhaps she was, just like her father.

Freud’s callous, even hostile, attitude to Tausk is apparent from his letter to Tausk’s former lover, and Freud’s devoted follower, Lou Salomé-Andreas, of August 1, 1919, thus written almost a month after Tausk’s death. n the letter, Freud wrote:
Poor Tausk, whom you for some time favoured with your friendship, committed suicide on 3.7. He returned worn out from the horrors of war, was faced with the necessity of building up under the most unfavourable circumstances the practice in Vienna which he had lost through being called up for military service, had intended to remarry only a week later - but decided otherwise.
His farewell letters to his fiancée, his first wife and to me were all equally affectionate, insisted on his clarity of mind, blamed only his own inadequacy and his failure in life; they gave therefore no clue to his last act.
In his letter to me he swore undying loyalty to psychoanalysis, thanked me etc. But what was behind it all we cannot guess. After all he spent his days wrestling with the father ghost.
I confess that I do not really miss him; I had long realized that he could be of no further service, indeed that he constituted a threat to the future.
I had an opportunity of taking a glance or two at the foundations on which his high-flown sublimations rested; and I would have dropped him long ago if you hadn't raised him so in my estimation.
Of course I was still ready to do anything for his advancement, only latterly I have been quite powerless myself owing to the general deterioration of conditions in Vienna. I never failed to recognize his notable gifts; but they were denied expression in achievements of corresponding value.
For my old age I have chosen the theme of death; I have stumbled on a remarkable notion based on my theory of the instincts. *
* Freud, Sigmund, 1856-1939; Andreas-Salomé, Lou, Sigmund Freud and Lou Andreas-Salomé; letters, (1972. pp. 98-99).

In her reply to Freud of August 25, 1919, Lou wrote: Poor Tausk. I loved him. I thought I knew him and yet I would never have thought of suicide. ... I imagine his death was that of a violent and yet, at the same time, a suffering man. (1)
And she added rather indifferently: Believed I knew him; yet would never, never have thought of suicide ... I cannot even guess which means he chose (poison would have been ever so easy for him, a doctor, to obtain). (2)
One can only agree, from what is known about Tausk, he wasn't the type that commits suicide, rather a seeker trying to find a fulfilment in life. As she told Freud, she considered, Tausk a frenzied soul ,,, with a tender heart. (3)
Apparently, Freud's belief that Tausk wanted to kill him was a figment of his paranoid imagination, rather than of a real threat to his life. Without doubt, it is highly unlikely that this kind of sensitive, tender-hearted person would even consider murdering the very mentor he worshipped is bizarrely improbable. But, blinded by his paranoia, Freud only saw in Tausk danger, not only to his own life, but also to his elevated position of a “pope” of the new “religion” of psychoanalysis.
Remarkably, Lou agreed with Freud that Tausk was, a kind of 'threat to the future' both for you and for psycho-analysis. Apparently, she shared Freud’s idea that Tausk's death, was a good solution to the "Tausk problem". After all, the dead don’t count, and she was, definitely, a survivor, siding with Freud rather than with her dead ex-lover, whom she allegedly loved.
The dead do not count, the world belongs only to the living, she may have said. Apparently, also in her view, having passed his “use-by-date”, Tausk was expendable. Without doubt, Freud and Lou were two psychopathic peas, in a psychoanalytical pod.

Three days after Tausk's death, on July 6, 1919, Freud informed his follower in Germany, Karl Abraham about the "suicide". Tausk shot himself a few days ago, Freud wrote, remarkably omitting the hanging, this time blaming Tausk's death on his wartime experiences.
You remember his behaviour at the Congress, Freud wrote. He was weighed down by his past and by the recent experiences of the war. And he made it clear that, even though, he should have been married this week, Tausk, could not struggle on any longer.
Notably, depending on whom Freud wrote, he provided a different explanation for Tausk's death, which confirms that neither was true. Showing his true attitude toward Tausk, Freud explained that, Despite his outstanding talents, he was of no use to us. (1) Apparently, this is the true explanation why Tausk was dead.
Almost a month later - after all the dead don't count - on August 3, 1919, Abraham replied. I had not heard about Tausk's sad end, he informed Freud, adding that, He had made a disturbing impression [at the congress] in Budapest. Siding with Freud, Abraham denigrated Tausk claiming that the latter was: The typical neurotic, who finally turns his painfully suppressed violence against himself. Even though, knowing next to nothing about Tausk, Abraham had his own explanation for Tausk's death. (2)
Even though Freud claimed that Tausk found it hard to adjust to the life after the war, he contradicted himself in the letter to Abraham of January 6, 1920, in which he informed him that, Tausk's courses, interrupted by the war, were attended by an average of 20–30 people. No wonder, jealous of Tausk's financial success, Freud informed Abraham that, The honoraria, at any rate, were high.
The professional jealousy may have been also caused by the fact that, unlike Tausk, Freud wasn't giving any lectures himself. I have given no lectures since the “Introduction” in 1917, he wrote, and will not do so despite having been given the title of Professor, because this “distinction” does not carry any teaching assignment. (3)
As the editor explained, Freud had [NOT] been appointed Full but only Titular Professor, a merely nominal title. And, the title was received not because of Freud's academic qualifications but, because of a bribe. (See the webpage: Fake professor).
