Am I in the right in this situation?

well my mum and dad have split due to my dads miss treatment...my mums moved out of the family home because my dad d and abused my mum..since then it has been me,my brother and my dad living together...i have no respect for him...and have offered him out to fight many times...i hate him and he takes the moral high ground all the time...am i right to be distance and agressive towards him...its the only way ino how to deal with it
