I'm going to bully a bully.
Why would you act in that way?
I don't like the idea of bullying. My parents told me many times that the root cause of bullying is always loneliness.
You said it yourself that bullying people is wrong, so you shouldn't sink to that level in revenge.  You should stick up for people who are being victimized, but don't victimize the perpetrator in response.
I have no idea why you think that is the best way to handle the situation... You are not making sense.
Well, bullying is wrong. Bullying bullies is still wrong, two wrongs don't make a right.
