I agree with the initial post as my default "door slam." I may dissect the unfortunate foes' character to their core before I leave (I like to think it's a loud slam before the door closes). But, that's the point when my attack ends, but during that phase, the point of no return, I'm invigorated.
*disclaimer: I use metaphors to illustrate my point of view (INFJ thingy), here I like to use Star Wars and Vampire lore metaphors.
Being endowed with "the counselor" and "the protector," when my "protector" circuit is activated, I step up to bullies, with the mindset, I'm all in to make him or her stop. I Jedi Mind trick them with precision guided psychological jabs, with soul piercing gaze to make sure they get what Im saying on a soul level, I'm fully committed to fight as a fall back, adds to my convincing and convictions stance. Bullies beware.
However, when I'm betrayed by a friend turned frienemy, and are of the cluster b category (no to low empathy) I get fired up to go head to head with interests, it's surgical and it's improv in the moment, so I don't have tactics, just strategy. I use their core issues, and drive a stake through their hearts. The darker the soul (dark triad) the more I'm invigorated, and I feel, INFJs are polar opposite to the darkest predators. INFJ have the same reading of people as a dark triad, but our compassion adds to our character, where they are predictable in patterns, our depth gives us an edge. I get pretty good at predicting the next move, sometimes surprised, but that just adds to my web of intuition and can only make me stronger. But, the dark triads are sadistic, and I get a trapped lone wolf mentality that's Machiavellian (being evil for the common good version). My subconscious picks up on everything, I connect the dots, I see the possible future outcomes. Wolves in sheep clothing are shocked to see my namaste change into a lone wolf, maybe its their energy I absorbed, but lone wolves are strong to leave a pack, and when injured (emotionally and/or psychologically) I'm a force to be reckon with, I'm a Master Jedi up against a Sith Lord, in real time I'm gathering info in disguised as flattery, I'm making remarks that slips under their radars that I'm aware, as my "hey, if you were paying attention I was cluing you in." (protector circuit).
I reach my tolerance top level, then the slam door circuit kicks in...game over (out of sight, out of mind)
I owe my enhancement to my INFJ traits to my developing observing ego skills.
