I'll keep looking for the paper I mentioned above. For now, I've found this information. For a topic like this, I think it is important to find
facts to build a conclusion, rather than relying on emotional responses.
There is actually information out there about Hitler's upbringing and childhood.
Quote:
"
This parental style was defined by Baumrind (1991) as an authoritarian style. Such a parenting style is characterized by rigidity, obedience without questions, and physical punishment. Research suggests that authoritarian parenting style is closely related to the development of aggressive personality and antisocial behaviour (Blitstein et al, 2005; Ruchkin, 2002)"

– There was a recent study (in the news last week) that backed the idea that "psychopaths" often have one of two upbringings, authoritarian or completely neglected. Kids brought up with parenting styles somewhere in the middle are more likely to be normal/average.

"
Hitler was described as a troubled adolescent who tended to find refuge in a world of fantasy. Historians refer to Hitler’s typical personality traits as impulsive, egocentric, cold, aggressive, unempathic, and tough-minded. This description tends to fit well into Eysenck’s (1977) theory of personality which postulates that such characteristics are indicative of a high level of Psychoticism. Eysenck’s theory states that when individuals with high levels of Psychoticism are put under great stress, the probability of developing a functional psychosis increases (Eysenck, 1997). In his more recent work, Eysenck (1998) suggests that psychoticism is also based on the cortical arousal level in the central nervous system, and subsequently is linked to conditionability and

conscience development. Impulsivity would be the crucial trait in the link between conditionability and personality. Therefore, highly psychotic individuals, just like extraverts, have a low level of cortical arousal, and are less easy to condition and more prone to developing antisocial personality disorders (Eysenck, 1998; Gudjonsson, 1997)."

Quotes:
"
Findings from the Coolidge et al. (2007) study suggested that Hitler suffered from a multitude of Axis I and Axis II disorders."
"There was a consensus among the expert ratters that Hitler reached the criterion threshold for a range of personality disorders including paranoid, antisocial, narcissistic, and sadistic personality disorders; the features of which are all consistent with detailed reports of his adult life."
"...The consensus profile revealed that Hitler probably suffered from Posttraumatic Stress Disorder (PTSD), Psychotic Thinking, and Schizophrenia-Paranoid Type. The DSM-IV (APA, 2000) symptom profile for Paranoid Schizophrenia seems to describe Hitler’s personality features extremely well."
"Additionally paranoid schizophrenia tends to be associated with anxiety, anger, aloofness, and argumentativeness. Furthermore, persecutory delusions in combination with delusions of grandiosity and feelings of anger predispose individuals to violence, while persecutory themes can leave an individual susceptible to suicidal behaviour. Individuals suffering from paranoid schizophrenia very often exhibit a patronizing and superior manner in interpersonal situations."

Quote from an unflattering editorial about INFJs
"According to psychologist and researcher Paul Wink, there are two faces of narcissism: The Overt or Grandiosity-Exhibitionism type, characterized by extraversion, self-assurance, and aggression, and The Covert or Vulnerability and Hypersensitivity type, characterized by introversion, defensiveness, anxiety, and vulnerability to life’s stressors.
Mr. Wink’s research found both sides are extraordinarily self-absorbed and share a common core of conceit, arrogance, and the tendency to give in to one's own needs and disregard others (Wink, 1991)."

A lot of people have a knee-jerk reaction that Hitler was not an INFJ, so I included some links to show that it is possible he was. (We cannot be sure because he didn't take the test.) Part of being a human being of any type is humbly admitting that some very unlikeable people could be associated with one's group. It doesn't mean the rest of us are Hitlers. I hope the provided professional quotes give insight into the why and how of Hitler.
