Actually... I know this will come as a streach to anyone on this thread, but Hitler's astrology had the potential to be a truly enlightened being, which he chose to abuse... rather than rise above. but thats a strech for most....
If you ignore the atrocities... the guy had amazing influence... had the stardome of a rock star, was considered a major sex symbol of his day. He had huge influence and manged to tap into the consious psyci to a near level of worship... and he is just a man - the big issue at the time was his influence on the collective consiouness.... not just himself in his own right I think.
It's easy to write evilness off as having poor social skills and inpatitude, but mass murderes tend to have high levels of social skills in order to influence... presumably Ted Bundy was possitively charming.
I'm not say for sure that Hitler was an F type (I was actually taking the piss about his being ENFP - just imaging him floating around talkign goobledy goop to people

), its all conjecture anyways, but he would have had to have increadible social skills to be able to comand that level of personal influence. I also think we get very little information about the man himself that is not spun beyond recognision, it's still increadibly rare/never seen in colour in the UK... such the propoganda... It's difficult to split him out from the reputation of the 3rd Reich.
