if your brain blocks out things from your childhood, it's for a reason

recently i watched this tv show, the prodigal son, his father was a serial killer and something happened during his childhood, but now he's trying to figure it out, but the more he figures it out the crazier he gets, and it's just like i would rather live without whatever that was blocked out of my memory, i don't remember certain times of my childhood, and i don't want to find out what it was, i don't know my just my opinion, what do you guys think?
