I really hated one of my former classmates. He was vulgar, annoying as hell and would always disrupt class which would often lead to all students being punished. He would also always bully younger students, going as far as to beat them up, then take their money. At first I would just try to avoid him, but then, after having classes with the guy for almost 2 years I snapped:

I really wanted to kill him.

I would constantly sneak stuff into his lunch, gross stuff at first, but then it became more dangerous. He had quite a lot of bad food allergies so I took advantage of that…
One time he just vomited in the cafeteria, another time he ACTUALLY amost died because his throat got really swollen from the allergic reaction.

Other times it was less subtle.
We had really big staircases in our old school with big wall like pillars, so you couldn’t see who was coming down the stairs next to you, if you were coming up. I’d often push him down the stairs, then hide. One time it broke his collarbone and two ribs.

I often fantasized about kidnapping and killing him, but I never did it because I knew I wouldn’t get away with it and then my (at the time 7 y/o) little sister would hate me…
(Ironic, isn’t it?)
I wanted him to suffer because he made everyone’s life hell. I wanted his dumbass parents to suffer, because they would always find some excuse for their brat.

I.
WANTED.
HIM.
F******.
GONE.
FOREVER.
WHATEVER.
THE.
COST.
MIGHT.
BE.

In the end I didn’t do it, cause of my sis, as I said.
And now I’m really thankful for it.
