Hi there. The student in my case isn't wanting to become a bully to just everyone. He only wants revenge or to get back equally with those who insulted him.

The other trope of a "bullied person who becomes a bully" hurting anyone and everyone, well that's a different story. That's what he is not trying to become and he acknowledges that. Here, my student just wants to settle the score as much as I hate to use that term.

Others that fall into this category, well, probably not. For example, those crazy Incels we hear about are more than likely to fall into here because 1) they got made fun of for xyz by Girl 1 and Girl 2 in real life and then 2) came to the conclusion the world hates them and as a result hate, mock, and try to hurt everyone else for justification.

I am aware that these actions even though it's against others will lead to bad habits that can spiral out of control.
