I think people who are unfairly(subjective) disliked become narcissist.
Eg
If I am training at a place, there are many training partners, and With all of them, I'm training fine, they are fine n happy, and okayness is there, and it's a good experience.
But then if theres a person, they dislike me, cause of just the way I am, my personality, maybe my reservedness, when I have to train with them their energy their body language, everything they don't want me to be practicing with them, they are not talking they got dead face, I feel bad and I don't execute properly, i execute at 50% . To do the practice right I gotta care about my self over what they feel about this, there's no other way, i gotta chose narcism in there.
I understand why narcissist, they just got hated and tried to do everything else n just said fuck it.
And I know people relate more to the victims of narcissistic abuse, so this will trigger those.
