I have a question regarding behavior towards our parents. I realize kind behavior towards one’s parents is obligatory. However, what should one do if one has a father who abuses his/her mother verbally and verges on physical abuse? Ofcourse, neither party is infallible, but the husband keeps criticizing his wife for every minute thing. Like criticizing her while eating and the food she cooks, using foul language, demeaning her all day. If the children try to intervene, the husband gets angry and says he can do whatever he wishes with his wife. What is the responsibility of their children in this case?

The children can defend their mother without being rude to their father.
They need to continuously remind the father about the good days. And then observe patience, however if it comes to physical harm the kids need to call the authorities and seek protection for their mother.
