Generations of Pain, Ends now

This is something placed in the My Hero Academia universe, with a villain being controlled by his father, just being another victim in the lines of people just forced to pick up villainry. He was never taught right from wrong, just being taught what he should do and listen to. He never knew that there was a world he could have chosen. Until he was put to be undercover in UA, the school of heroes. Over a little over a year he met some of the greatest people he ever knew, finally learning what being happy was and what having friends was like, and when he's forced to leave this once again and betray them all; it turns him upside down. He begins to spiral out of his mind, his kills he enjoys, feeling no remorse. He forgets happiness, not caring of others thoughts and blindly follows his father for the fear that his bloodlust may take him over if he tries to stray. What happens if he's given a chance at redemption?
