I feel like a traitor.

I feel like a traitor for feeling glad that a kid I don't like got injured. This kid has been tormenting me during lunch duty for 4 years now. Most kids grow out of their middle school behaviors when they get to high school (at least enough to behave and be respectful) but not this kid. He continues to bully, prank, and disrupt. He makes fun of me daily and does his best to show disrespect to me in front of the other kids. Every time he does what I ask he makes sure he does it in a passive aggressive way just to prove he's not listening because he's scared of me but because he feels like it. He's ╤taken scissors to kids' things, hit a kid in the head with a baseball, lit a condom on fire and threw it in the trash, stolen food and eaten the majority of it but left a small piece on the ground, lit a piece of paper on fire, and countless other pranks that are disruptive or dangerous.<br><br>Today, a kid accidentally threw a ball at the back of his head and he hit his eye on a bar. I don't think he needs surgery but he's at the doctor getting it checked out. I'm upset because accidents can happen but I'm also glad that this kid isn't around to torment me for the day. Even if he's not there I have to deal with his friends who are just as bad. I feel awful that I'm not sympathetic to his injury but after years of being tormented I'm just relieved that he got what was coming to him. I feel like a terrible person and traitor of a teacher. What's wrong with me?!
