Some commentators have seen Jung's conduct as a professional boundary violation, while others have seen it as an unintended and forgivable consequence of early experimentation with psychoanalytic techniques. The historian and Freudian psychoanalyst Bruno Bettelheim commented on her treatment and the apparently beneficial result, noting that, "However questionable Jung's behaviour was from a moral point of view...somehow it met the prime obligation of the therapist towards his patient: to cure her”. By contrast, Peter Loewenberg (among others) has argued that it was in breach of professional ethics, and that it "jeopardized his position at the Burghölzli and led to his rupture with Bleuler and his departure from the University of Zurich".
