My father displays abusive behavior towards me and my family. He is physically and emotionally harmful, forced me to work inappropriately, and has had many issues leading to police involvement. Am I allowed to cut ties with him?
Not at all. Your father remains your father and you must keep respecting him and treating him in the best way even if he was a very bad person. Even if your parents were Mushriks (Polytheusts), you must treat them nicely as we read in Quran. (Sura Luqman ; 15).
Wassalam.
