Having seen the affects of bad parenting firsthand in other families I have to say that my father was not bad, it was rough but not horrid.
My dad had control issues and got angry when I didn't do what he wanted. This control extended to my mom as well but trying to control her is like trying to stop a tsunami with a sheet of paper, so he focused on me. For a good ten years of my life I was extremely submissive, every time I tried to stand up to him I was punished, nothing too serious; the usual shouting, the occasional slap, groundings but the punishment never suited the reason. Every time it got too rough my mom gave him a choice: us or the road. It always snapped him back to reality and he stuck with us. When I was fifteen both me and my mom stood up to him, we showed him how his behavior influenced us, and he changed for the better. He still has the occasional issue that will irritate him now and again but he doesn't loose control of his temper anymore.
I don't hold it against him because I heard stories about how his father treated him, his siblings, and his mother. They were to be present but silent, they only existed when it was convenient for my grandfather. If they didn't do what he wanted when he wanted them to do it they were severely punished. They were going to be what he wanted them to be, my aunts are all stay at home moms and my uncles and dad are all pilots. With an upbringing like that, that being one of the only frames of reference he had for parenting... I just have to say my life could have been a whole lot worse.
However thanks to him I learned how to read peoples moods with almost creepy accuracy, how to diffuse heated arguments, and a shitload of humility. It has also made me who I am today, the fear of my early childhood combined with a mild chemical depression drove me to escapism which boosted my imagination and creativity. It also made me mature incredibly fast into a person that my dad now is proud of no matter what I do with my life.
