And somehow dr Freud hypothesized that Hitler actually get the Syphilis from a Jewish prostitute that looks like his mother. After his disease cured by then prototype Antibiotic, he also cured from his racism and megalomania.
Actually, Hitler was pretty much cured using Compounds 606 and 914 by 1935, mostly because that strict vegetarian diet he maintained helped in his recovery (in a way). I'm not sure if he was ever given antibiotic treatments, though.
I think the loss of so many of Hitler's close associates at the Beer Hall Putsch was why the Conservatives in the Nazi Party were able to "ease out" him from running the Party. Prominent of the friends killed were Rudolf Hess, Alfred Rosenberg, ex-World War I fighter ace Hermann Goering, and a fast-rising "star" of the Party at the time, an agronomist named Heinrich Himmler. We know that Ernst Roehm subsequently resigned from the Party, took a job advising the military in Bolivia in 1928, and spent the rest of his life in Argentina after the a military revolt in Bolivia in 1930 forced him to flee that country. Roehm's memoirs of the early Nazi Party--published in 1940--provides much of the insight of what Hitler intended for the growth of the radicalized Nazi Party.
