Is it bad that I'm nice to my dad?

I didn't have a very good childhood because of my dad. He was always drunk. He drove drunk with us in the car. He often passed out, and my underage sister would have to drive. He would often spank us too. Sometimes with a belt. I remember we had a dog, and one time the dog chewed up a shoe and mu dad kicked the dog do hard she pissed all over the place. Well, my dad has been sober for 10 years. He is certainly a better person. He's apologized for always being drunk, and for being a jerk. He hasn't apologized for spanking us or anything. I think he still thinks kids should be spank. Same with dogs too. Thsnkfully he doesn't have a dog. Well, we have a really good relationship these days. I call him every few days, and he calls me too. Just to see how we're doing. I was gonna call and tell him happy father's day, but im not sure if I should considering how he treated us. What do you think?
