I'm going to scream at my father to let him know he's an asshole. Do you think that will work?
I'm not sure. Why do you feel the need to do that to him?
Because he's a huge asshole.
Sometimes it can be healthy to let these bad emotions of yours out.  Repressing them just makes you into a miserable person.  I'd still suggest, however, that you let them out by talking to him rather than screaming.
I don't think I can do that, I'm going to go crazy and I just want to release some hate. He needs to know how I really feel.
How do you think he will respond when you start screaming at him? Don't you think that he will probably just start screaming at you also? Maybe if you try talking to him, he will be more receptive to hearing what you have to say.
