Did you know Freud's daughter was a 50 year old virgin? That begs the question, how did Freud become so popular back in the day? Well, it turns out the answer is the wealthy at that time wanted women to remain virgins so they could peruse them for selection and marrying them off.
If the results were horrifying the means to the end were even worse. You might take a look at Edward Bernays, Freud's nephew, for some interesting information about controlling populations through mass media.
Edit: The point being, Freud and his family were NOT healthy emotionally. They were analyzing their own behavior and acting out horrifying experiments with horrifying consequences. In my opinion, the holocaust was a result of their influence. Control seemed possible. E=mc2 too.
