"The day the child realizes all adults are imperfect, they become an adolescent; the day they forgive them, they become an adult. The day they forgive themselves, they become wise."
(Alden Nowlan)
Most children do believe until some point that their parents are perfect and it is part of growing up to realise they are only human.
I do not think my parents are perfect anymore - I got violently pulled out of that belief very young, actually. I do realise that they mostly did what they believed to be best with the necessarily limited information, knowledge, perceptions, social conditioning they had at a given time. Mostly, they did good. I am very grateful for some aspects of my education and intend to reproduce part of it with my future children.
Word of advice: You will need to understand and deconstruct your education, even if it is to realise what was good about it and keep these good part, if you want to properly raise your own children. Try discussing these points of your education with your parents - possibly when you don't hate them for them anymore
