Inspired by a post I responded to in a specific thread about MBTI on a Swedish forum, a user who asked for some examples of INFP bad guys, which I shared a few of my own conjectures. I thought it would be interesting to have a thread about evil people/wrongdoers throughout our history. This thread is of course limited to real life people, although comparisons to fictional characters of the same type as one of your specimen can be tolerated. Due to my extensive interest in criminology and forensics, I am much more well-versed with serial killers and gangsters, rather than dictators.
I'm just going to start off with some people I typed a long time ago that I can think of at this very moment. Will return later with more and eventually even new extrapolations of mine.
John Gotti (ENTJ, my all-time favorite gangster)
John A. Gotti (INFP)
John List (INFJ, took a very long time for me to finalize despite being my favorite case of all time)
Mary Bell (INFP)
Andrei Chikatilo (INFP, possibly ENFP, Fi-Ne vs. Ne-Fi)
John Christie (ISTP)
Anyone have any suggestions for people like Herman Webster Mudgett or Albert Fish? I haven't really ruminated one bit about their type, but my impression of them is that they would be comparatively easy to make a qualified type guess, once you start thinking about them from a Jungian perspective.
