Revenge Doth Not A Hero Make

Two boys consumed by spite

One is a smart but quirkless freckled boy who finally snapped and vows to get revenge on his bully as well as the messed up hero system around him.
The other, the son of the number 2 hero, is a pawn of his villain older brother and of the League of Villains in a game to recruit one of UA's finest upcoming first years to help in destroying hero society.

What happens when both target a student known as Bakugou Katsuki?
What if one of them is hesitant?
What if both are blinded by short-term revenge?
And what happens when these two meet each other?

Villain!Todoroki and villain!Deku au kind of thing :)
