Remember the name

Over the course of my life journey, I have met many good people, and made some rivals as well as a few enemies; I am no angel. I'm just a normal human being, personality-wise. And all these enemies/rivals, can we even consider them real enemies or rivals when we forget about them after awhile?
Some we have an instant loathing for, but even when we see them on the streets we nod to them, tell our friends: hey that guy is a douche, and forget about it tomorrow. Some used to be the best of friends, but became enemies by a twist of fate; either due to a mismatch in personality, or even escalating of simple misunderstandings.
But throughout my 22 years, I have never ever met someone that i could loathe and hate so much with such passion and consistency that even after 3 years, the mere mention of her name or a thought of her brings a burning rage into my soul. Someone who has proved herself to be pure evil; bad to the bone. Someone who will bring harm to another without even the possibility of benefiting herself; one of my friends once called this: shun ren bu li ji. If you harm another to benefit yourself, you are a dick, but there are millions of people like you in this world. To reach the level of harming without benefits... you are truly one of a kind.
F.C <- remember the name. I know i will.
