(2) Where a person commands the killing of another person, knowing that the killing will be unlawful, then, although the offence of the person so commanded maybe reduced to manslaughter, or to an attempt to commit manslaughter, if he or she believed that he or she was under a legal duty to obey the command, the person giving the command commits the same offence as if the person commanded had not believed himself or herself to be under a legal duty to obey the command.
