Yes, i'm an INFJ.
I've just read about BPD, i have some traits from there, but only few, since i don't have fear of being abandoned or alone because i need to be alone to recharge myself from other people, the traits i have are self harm and explosive anger, i'm in total control and it's real hard to get angry, it's rare and it hasn't been happening in years, but when it does it's like a devastating bomb that's harmful to me and others, i mean i don't even remember the outcomes of it when it happens, it's people who tell me what happened. You have been helpful, for that i appreciate your time.
I am very very vindictive and vigilant but only to those who deserve it and i'm in 50 / 50 control, for example when someone does wrong by my friends or me or is abusing animals and i see it, i have this feeling even in my hands like burning from within to restore the justice, so much ambition and strength, the very feeling of power and that the world feels like it's mine, it's real dark and bad, i'm happy it haven't been happening in a while, it used to when i was in my home country, the thrill and the revenge can be like an addiction, it was very hard to control myself from it, when it happens i feel like my skills are set to maximum and i first break em mentally then physically.
It's easy to loose it, once i was very close to the end line but i managed to stop myself from going further and i crushed my hands into the wall so that i don't become a murderer, i know it sounds bad but it's truth i'm an animal lover i have 2 cats and 1 dog and i have always lived with animals, they are sacred to me, no one can hurt animals in front of me and get away with it. I think sometimes being vigilant is nessecery, i can also live and breathe without being vigilant, that side comes only when nessecery.
About the universe, i do have faith in it, i'm a nature lover also, when i go to the woods i speak out loud and it feels like the universe is somehow getting my message, i say i want this i want that, and after days weeks or even months i get opportunities that if i take em successfully i can get what i wanted.
You might be close but i don't think you're like me, i don't think i'm a psychopath anymore, even though when i was in the navy for 2 years i've seen murders and it doesn't move me, my mind is bulletproof and i'm not paranoid, i agree that psychopathy is a scale, but impulsiveness i think is more of a sociopathic trait.
