I hate my dad, am I justified?

He hit me for calling him a bastard, which I only said because he was giving me the evil eye. And he ruined my mother’s life. He treats her like a servant or something and he never exercises so he has a HUGE belly to the point where my mother isn’t attracted to him anymore and seeks attention from other men. Also he looks at me inappropriately it’s unsettling. He also says bad stuff about my grandma, who is a really nice person.
