Well, he's your father afterall and you should never kill him
unless it's life and death situation and he's taking a knife going
to take your life. If that's happens, go ahead and defence yourself
and hack off his head. 
You know, there're some people who grew up without knowing and
having their father beside them and how they wished they had one
from hell. :p
Ignore him if you really dislike him that much and don't let him
take up any memory space in your mind constantly. There're better
things to think of, especially your own future. Your father is not
going to be in your future till you die, and you're definitely
going to outlive him. When that time comes, won't you be real sad
and wished that he'll be alive again and irritate you? 
Regardless of how terrible your father is right now, he is your
father and you should look forward and remember the good and happy
things that both of you have experienced. Anything that's bad
memories should be forgotten once it's over...don't bear grudges
against family.
Family will always be there to support you in whatever situations,
and I'm sure your father loves you a lot and will definitely stand
by you if you needed him to be. I'm sure he'll gladly donate a
kidney for you if he have to do so to save your life.
Some people became evil because they grew up without their
father...for example, Dr. Evil from Austin Powers? 
Ignore and Forget, for forgive is divine and forgiveness need to be
earned.
Good luck.
