Actively harassing someone or a group of people is bullying behavior. you are not the victim, you are the bully. There is no 'well he/she/they did this to me so that makes it okay for me to do xzy to them'. No, it doesn't. I do not care what narrative of events you've cooked up in your mind to try and explain away the bullying and stalking; you are not a good person at all.
