It's Called Rehab for a Reason

This is a class 1-A rehabilitation AU. But instead of it being only one student in the rehabilitation program it's all students. It will make more sense as you read it.

Izuku Midoriya is a teenage boy who had delt with over 10 years of abuse and bullying. His mother died when he was younger by the hands of his father, his father never got convicted though. This lead Izuku to paying his father, bullies and heroes back himself.

Shoto Todoroki is the child of a low ranked villain Rei Todoroki and the second pro-hero Enji Todoroki. When he was a young child his mother was sent to a mental institute because his father had made such an impact on her that she burned her son and later admitted to her crimes. This lead Shoto to realize the difference between heroes and villains.

Katsuki Bakugou grew up with a very issued mom and a quiet dad who did nothing to stop her from mentally abusing his son. One day Mitsuki went as far as to physically abuse Katsuki in front of his father, who done nothing to stop it, and later Katsuki started theiving, drugs, bullying and then killed his mother and father and never left the habit of killing.

Eijiro Kirishima was a sweet boy, 𝘄𝗮𝘀, until he watched his father shoot his mother right in front of him. Something in Eijiro snapped which resulted in him killing his father and then running away killing, torturing, and stealing.

Denki Kaminari, he was always helpful toward people and enjoyed seeing people happy. Denki was that way until his mother came back which resulted in him getting beat on a day to day basis along with his father. One night Denki had had enough and killed his mother in her sleep and then left.

These five teenage boys along with others are now known as the highest ranked villains alive, Killer Bunny or Deku, Frost Burn, Ground Zero, Blood Riot and Chargebolt. How will these villains reacted to being given the chance to start over again. Or being able to live like semi-normal people.
