Abusive parent

What are the obligations of a child to a parent who has emotionally abused their children and refuses to take responsibility or pay any bills relating to the children and household expenses? If this parent keeps late hours and is difficult to live with, can the children move out or make him move out (with the help of other relatives)? And will my lack of affection toward this parent ( my father) be a sin? I am afraid of him testifying against me on judgment day, but to be honest I feel life would be easier without him in my life. Am I evil for feeling this way? Please advise as I am very distressed about this.
