You think he was revolting from boredom? C'mon...
No. The fact that you would respond that way merely from me saying Che is ST means you seriously need to go back to the books.
I've read a lot about him, and he does definitely not come across as a Perceiver. My vote is on ENxJ.
His logic and tendencies towards emotional decisions were about equal, so i'll make that an X.
At least in my head. I'm not saying F's can't kill people, but he definitely valued justice higher than mercy. Nothing wrong about that. But a clear NF would maybe have pardoned a few more of the old fascist pigs officials.
As I said, he surely can't have been much of a Perceiver. Sure, he was adventurous and shit. But he was really a doer, with a ton of willpower and drive. He had struggled with asthma during his entire life, and even had attacks during the revolution. Didn't really stop him for long! He was also a workaholic, and not at all a laid back kind of person. An NF would have been more of a romantic, or at least caring for his family, Che basically ignored them. He quite literally spent all his waking time writing or working for the revolutionary movement.
A "doer" as opposed to what? A thinker? An observer? A commander? A doer as oppsed to any one of those things would be well suited for most EPs, as well as ISTPs (just maybe ISFPs, though I doubt Che was ISFP).
Those who use Judging functions first tend to be more deliberate and paced than those who use Perceiving functions first, espeically comparing the Extraverts. EPs are the most impulsive of all, while EJs are not only deliberate, they are more bound perameters than IPs are. That being said, IPs are for their own reasons the most deliberate of all (remember, they use Ji first... not Pi).
It is this "doer" behavior of Che that is one of the reasons I figure he is a Perceiver, actually. He was extremely experiential. Everything was an ongoing process, and unmeasured endurace test for him. I'm not saying all Ps are like that (not even close) but it's a lot weirder for a non-P to be like that.
Indeed, he is likely not a Feeler. He was terribly impersonal, and emotionally distancing. That he supposedly fought for an "idealistic" cause says nothing about his type. We all struggle for causes, and the very concept of a cause itself or how people are connected to them is extremely vague and interpretive.
The way he went about the cause is more important. He had a knack for the military way of doing things, but he was no great communicator, and not a sociologist. Part of his downfall came from not being good at gauging the minds of the people, or knowing how to persuade them. His approach was practical and tactical, and he took things one step at a time, not attached to the past, not planning for the future. He was in the moment.
So, being impersonal and unsentimental, and indeed, more inclined toward justice than mercy, he seems like a T. Being his focus was local, present, linear, concrete, and direct, he seems more like an S than an N (it's worth noting that Castro was probably a major Inuititve influence in his life). But being an ST, was he an STJ? Absolutely not. This man is not a man of strict guidelines, of familiar establishments, or familar facts. He was someone always throwing himself onto new experiences, hands on, with
ad hoc approaches (he did literally write the book on Geurilla warfare). He was an STP.
So E or I? I'm really not sure. At the moment, I'm inclined to think ISTP, but I'm not elaborating right now because it feels too shakey to me.
