Misery Loves Company (Please don't bully)

I hate this. I hate when miserable people do their best to make others miserable too. I have dealt with this from one person for four years now. I have reached my breaking point. Yes, I am venting. Sorry to anyone who reads this, but it needs to be said. And there is also a valuable message to this vent.
To You Know Who: I don’t care how much you hate someone. I don’t care what they have done to you. NOTHING gives you ANY RIGHT to do anything to that person. NOTHING gives you any right to threaten someone. NOTHING gives you any right to turn the whole school against that person. NOTHING gives you any right to tell lies and socially isolate that person. NOTHING gives you any right to have people send indirect insults through innocent people and then later get in their face and threaten them, with a finger in their face.
Four years! It has always backfired on you! The first time, you tried to have my friend all to yourself. You told lies about all her friends to her. For some reason, you also gave her death threats. She couldn’t sleep at night! She was afraid to come to school! The drama you caused split up the group of me and my friends. I permanently lost many friends because of it. And now you are up to your tricks again. You are threatening another friend of mine. You are turning everyone against her. You are doing your best to make her mad and ruin her life. And AGAIN you have split up a group of people. I have lost friends AGAIN. This time I had someone come and use an aggressive tone with me and shove their finger in my face, making threats to me. I am not involved! Why am I being targeted now? I never did anything. And my friend never did anything either. The things that happened to you were all your own fault. You made your own problems, not her!

NO ONE has the right to make someone else feel bad and miserable. NO ONE has the right to harass someone else. NO MATTER WHAT HAS HAPPENED! Everyone knows my passion for opposing bullying. Please people, turn the other cheek. Revenge only brings more chaos. Making others miserable may seem like it makes you feel better, but it only brings you down. You will still feel miserable. Stand up against bullying.
