I honestly wouldn't be surprised if Hitler was an INFJ or close to that type. He had a gift with worlds, he fought hard and planned extensively for a large-scale "ideal" (obviously a perverse, skewed one... there are UNHEALTHY INFJs afterall), despite being a public speaker he showed many signs of introversion. And he was a vegetarian and showed passion when he spoke, which may push him towards the F type.
Obviously he did horrible things that we can't fathom doing, but there's all different perspectives and personal codes that an INFJ can have, so who's to say he couldn't have been an INFJ.
Is it that by its indefiniteness it shadows forth the heartless voids and immensities of the universe, and thus stabs us from behind with the thought of annihilation, when beholding the white depths of the milky way?
