Is obedience to a father permissible after he has sexually harassed his son's wife, and is boycotting him considered an act of disobedience to parents?

If a father harasses his son's wife, this is an abominable act, and he must repent. The wife must not uncover her head in front of him, nor be alone with him. Despite the father's misconduct, obedience to him and treating him with kindness are obligatory upon the son. The son must denounce his father's action and call him to repentance gently and kindly.
