I'm curious about seeing the dark side of each type. Villains, antagonists, tragic antiheroes/antivillains, etc. I just want to see fictional examples of our type 'gone wrong'.
Here are a few I've thought of (I haven't quite figured out how to justify them yet, but here they are anyway):
WARNING: There could be spoilers.
INFP: Frederick Zoller (Inglourious Basterds), his dogged pursuit and defense of his ideals (be it himself or his nation) seems to be a complete instance of Fi/Ne, and he reminds me disturbingly of one of my INFP friends in his approach of things.
INTJ: Shosanna Dreyfus (Inglourious Basterds), could be an INFJ (but I could just be fanwanking. I've seen people type her as an INFP, but I feel like she's more Dom Ni than Aux Ne, and that her decision to...do what she does in the movie is partly triggered by what happened to her family in the beginning. In other words, I believe the seemingly 'Fi' nature people pick up on her could be a Ni-Fe loop if she were INFJ, or it could be her Tert Fi at play if she were INTJ)
ENFJ: Col. Hans Landa (Inglourious Basterds), many people type him as an INFJ, but I feel like he has more of an extraverted focus in his approach.
These are the only examples I can think of off the top of my head (I just watched Inglourious Basterds for the 111,225th time, so it was already on my mind). I want more examples, though! Please, share! =D
