Whom did Macbeth kill in the battle with the English forces?

Hard to say exactly. He killed Duncan himself, so he doesn't count. He has Banquo killed. He has Lady Macduff killed. He has Macduff's children (unclear how many of these there are, but more than two anyway) and Servants (again unclear how many) killed. Do we want to count the soldiers who died fighting for him? Probably not.
