Or younglings. Because of his actions, he caused his wife to lose her will to live (which was totally in character, too) . (What I think really happened is that she was supposed to die from Anakin force-choking him, but Lucas wimped out.)
I don't think Ne is very tied to the unconscious at all. It seems more like a mixing matching of ideas.
I wonder if it even makes sense to think of the behavior of functions "by themselves." It probably makes more sense to think of function pares... a perceiving function and a judging function acting in concert, like Ti Ne or Ti Si. I mean, the judging functions need preception, "food", right?
You're mentioning a few ideas here, and I'm not sure how they're all related. But in general, the more the introvert tries to strengthen himself against the objective influence of the external world - especially that of people or society (this is the Fe you're referring to) - the weaker he becomes with regard to it.
Judging functions need something to judge. But more interesting is the fact that introverted judging (Ti and Fi) is insecure in its judgments regarding the external realm. It has "poor" judgment toward that, but excellent judgment regarding things of the mind - theories (math, science, sociology, psychology, etc.). Extroverted judging, on the other hand, appears to have excellent judgment with regard to external matters, but it has "poor" judgment regarding things of the mind.
So if you meet anybody who appears to have poor judgment, that person is a Perceiver. Those with excellent judgment are Judgers. But keep in mind that, with regard to internal focus or attitude, which is more difficult to discern, they are quite the opposite.
I would say that extroverted functions are not consciously tied to the unconscious, and that introverted functions are more consciously tied to the unconscious.
