Is it normal that i don't have a good relationship with my father?

I've never really had a good relationship with my father. I think it origins back when I was a little child and even before that. I believe my father's always been an aggressive person, lost his temperature easily and never respected anyone. As far as I can remember he always had fights with my mom (and when I saw fights I mean verbally, true though that he did hit my mom a couple of times), broke her porcelains, crashed her other objects like chairs and stuff. He treated her like a dog.. And still does.
Plus, back then my father wanted to make money. They established a firm with my mom - with my mom's knowledge and qualifications - but still, my father handles all the money they earn. Like he did some shit beside being like an assistant to my mom. He even threatened my mom that if she ever leaves him, he would kill my mom and my mom's family. So he kinda like bonded himself to my mom and us with my brother - and of course the money.

Well and I could tell stories like that the whole day, but the point is not that. I really don't know that is it just me that I can't have a normal relationship with my father after all the things he did (and I don't even want to)? Because he's not like that every day, he has periods when he's happier or acts normal or stuff. But still, that shit is still in the background that I can't forget or forgive. My mom says I could try to make a better relationship with him, and even she has (yes even after all that thing), but I just can't. Fuck it. Would I be the crazy one?
