I once read somewhere that being an enneagram 8, in its interactions with MBTI, theoretically lowers one's "feeling" and raises one's "thinking" and "sensing." As a particularly ersatz ENFJ, I definitely relate to this. I vibe very "mild" EXTJ/ESTP in my day to day interactions, especially at work.
1.) I have a confrontational, in your face, intense, aggressive bent and I love "conflict (arguing, debating, martial arts)." The emotion I'm most familiar with is anger. Admittedly terrible (lol), but I generally channel it to drive my endeavors, primarily in the form of righteous indignation.
2.) Most of the time, I'm very much the lone wolf doing his own thing, going where he pleases, without people (and their thoughts, wants, desires, etc...) factoring much into what I do or how I feel. I use Fe to get things done and accomplish my goals (via people) but I don't possess a general, all encompassing Messianic love and sentimentality for humanity.
3.) Objective truths, logic and rationality are extremely important to me. One of the reasons why I never resonated with most ENFJ profiles is because there seemed to be an emphasis on weepy, maudlin hyper-emotionality, irrationality and a struggle with logical systems.
4.) I'm more so willing to do what others might see as mean or callous for the sake of the greater good rather than selflessly martyr myself and others in the name of being "nice" for the greater good.
