Those who are not familiar with such conditions can hardly imagine the results, especially when the mutual differences express themselves in the form of brutal attacks on the part of the father towards the mother or to assaults due to drunkenness." (Langer, "Mind of Adolf Hitler"). He also seems ha have been his mother's favorite and the beneficiary of generous flows of love from her part, contrary to his father's severity. Langer also draws the conclusion that Hitler was influenced in a very serious degree by his father's personality and often confusing way of behaving. His father's deeds seem to contradict themselves in his attempt to present an entirely different image to the society than what he really was at home: an unreliable drunk who physically and verbally abused all the members of his family. As Langer also points out in his study, Hitler looked in his first adult years as a soldier to the prominent male figures to replace his father authority, just as many Germans looked at him, later.

His sentimental involvements are also casting some light on the roots of his neurotic mind. His sexual life is impossible to be described because the reliable sources are...

Fact is that all his partners were women at least twenty years younger than he was and they all attempted suicide at one point or another. (Waite, Adolf Hitler's Guilt Feelings: A Problem in History and Psychology, p. 234)
Hitler suffered from a severe form of neurosis that made him unable to distinguish reality from fantasy and allowed him to see all the atrocities he gave birth and agreed to, that is beyond any reason of the doubt and it is proven by his deeds above anything else.
