Throwaway for obvious reasons.

I stopped smoking pot about a year ago for just this reason. Whenever I was stoned I would get so violent and aggressive that I would find any excuse to horseplay with my friends and I would never want to stop. There were two particular instances where I choked my friend unconscious and another where I dislocated my friend's shoulder via kimura. That was all fun and games. Then it started getting psycho.

It started at my friend Val's house. We were all blowing down in his living room, smoking joint after joint, when my friend's spoiled-rotten dog walks in with this goofy-ass smirk on it's face and jumps on the couch next to me. Everyone is in the other room cooking food to quell their munchies at this point and I'm all alone with the dog. I remember just looking at it's wet eyes and thinking about how much my friend's family spoils it and how it's never felt pain before. I start small. I pinch it a little bit here and there and it gets annoyed and barks which bring my friends back in the room. They eat on the coach and go back for seconds. The second they leave, I turn to the dog and beat it senseless. Everytime it tries to get away I pull it back and slam my fist into it's jaw. Everytime I strike I can feel that this dog is feeling fear for the first time and how I'M the cause of that fear. I feel power like never before. Soon it evolved. I broke my friend's pet bird's wing with a punch and I would catch snakes in my backyard and drown them. Once I stopped smoking weed I thought it was all behind me. But another friend of mine has pet rats and I want to hurt them so bad. She's always skyping me and showing me how she fucking spoils them and cuddles them. I want them to feel fear and pain so bad that sometimes it aches inside. I plan on going over her house and torturing them. I go to my local pet store every other week and kill rats. Rats are my favorite. They show so much emotion when they suffer.
<bot>: something's wrong with me. I kill animals for fun and it feels so good. I dont do anything illegal but that. Rodents are my favorites. Two rats have died thanks to me.
