If you bully the bully are you a bully or a hero?

I think more so on the victim or (victims) standpoint, their a hero for making their bully know how it feels like to be bullied. Because some bullies don't even know their one until their called out for it, or more on a malicious pov they know what their doing but since no one is stopping them they just keep pushing the victims off the edge for their entertainment..worse case scenario go "rip" when it's too late.
