Everyone uses both T and F, so to the extent that he is part human, so will Spock. The T/F in our type just indicates which we prefer. I associate kohlinar more with the stereotype of INTJs trying to act like robots and claim they have no emotions. (Not true, but could be a goal and possibly achievable in the aforementioned fantasy world process.)
Yes. I'm remembering how Spock decided to back off from the process after V'Ger showed up. V'Ger was just a destructive child, as Spock pointed out. Again, I think Star Trek: The Motion Picture is underrated.
I don't think that Kohlinar would make Vulcans like V'Ger, but I'm not sure how Vulcans who undertake the process act.
I'm gonna get myself in fighting trim... scope out every angle of unfair advantage. - The Mountain Goats.
In the human world he's ISTJ, in the Vulcan he's ISTP
