Doing the same thing/s the bullies did to their victims as a punishment is a bad idea

I believe that tormenting the bullies, just like the bullies did to their victims is a bad idea. I'll tell you several stories about why it isn't a good idea. Story 1: The Result For Physical Bullying [One day, some guy decided to go out and torment somebody. Then, he found his victim. He punched and kicked his victim, until the bell rang and lunch time was over. The tormentor warned his victim not to tell anyone, or else there'll be serious trouble. This happened day after day. Until one day, the victim was tired of keeping the secret and told his teacher. The teacher then called the tormentor/bully to come over to her. Then, she called for the class's attention. After she got her classes attention, started to punch and kick the bully, until there was severe bruising. Then, the teacher explained to her classed what had happened every lunch time to the victim. Then, the bully got into rage and started crashing and ruining everything he can. He threw chairs, and got the classroom into a mess. The teacher got mad and sent the bully to the principal's office. When it was home time, the bully told his parents that his teacher was abusing him. The next day, his parents talked to his teacher and his teacher told him everything that happened yesterday. Then, they saw the victim's parents and the the 2 families started to argue with each other and the teacher.] This is one problem. Story 2: The Result For Verbal Bullying [There was a fat girl in some boy's class and he decided to torment her about her obesity. "Fat pig," he said, blowing a raspberry at her. "You're no fit to be in any sports team, so don't even dream of making it in the try-outs." he said with a smirk. The girl looked upset and walked away. The boy ran in front of her and stopped her before she could go any further. "Oh, no. Not so fast, Fatty because we're not finished." he continued. "What do you want?" asked the girl. "What do I want, huh? What I want is to tell you that you are too fat to be useful or sporty." he replied. "I don't have time for this. Now, if you excuse me, I want to go somewhere." she said. The boy blocked her way again. "No, I don't excuse you, Fatty." he said. "What is your problem?" she asked him. Then, the bell rang. "You are to meet me here tomorrow. If you don't, you're dead pork." he warned her. The girl got more annoyed and upset by his harassment by the minute. This happened day after day, until the girl was feeling very sick of keeping this secret and told her teacher. The teacher then called for the bully and the class's attention. Then, he grabbed the bully by the shirt and started swearing and teasing him. Then the boy got scared and talked back. Then, they argued and argued until the bell rang for home time. The teacher quickly told the class what the bully had been up to every lunch time. When the boy got home, he told his parents that his teacher grabbed him by the shirt and swore and teased him. The next day, his parents went to complain to his teacher about how he was treated. The teacher told them that their son had been a bully. But they argued and argued.] Which is why I think that tormenting the bully back isn't a good idea.
