I'm so fucking confused what the hell happened in the flashback

ml has a pheromone problem, bc he was forced to grow up in wolf form/his daddy refuse to give him proper medication.
he has pheromones shocks were he became basically a feral wolf and hurt everyone/everything on his path, including himself (remember when the puppy hide under the bed? It was one of those episodes)
he indeed hurt his siblings but didn't know it was him. He dad did it bc he wanted to make him a overseer, HE WAS A CRAZY MOTHERFUCKER

ohhhh thank you very much !!
