You cannot break your sister's boyfriend's legs. It is illegal to directly take measures to injure someone else. However, you can report his abusive behavior to the authorities and request legal action be taken against him. You can also look into resources in your area that provide victims of domestic abuse with assistance and advice on how to get away from their abuser safely.
