The wrong people. In order to thwart the prophecy about Banquo's children becoming kings, he has Banquo killed, but not his son Fleance. Fleance will go on to become the ancestor of kings. Macbeth killed the father when he should have killed the son. Then, in order to try to thwart the prophecy about Macduff, he has Macduff's son (and wife and other children) murdered. Macduff will go on to defeat Macbeth. Macbeth killed the son when he should have killed the father.
Lady Macduff tells her son that his father is dead because he has fled and left them without protection, which she views as a cowardly act. She emphasizes that his father is a traitor and no longer cares for them.
