In "Macbeth," how does Macduff receive the news of his loss?Macbeth act4

Macduff undergoes different emotions when Ross brings the news from Scotland concerning the massacre of his family. At first he asks, "How does my wife?" (4.3.203). Ross is not honest and answers that all is well. However, as the conversation continues, Ross relents and gives him the news of his family's destruction. Macduff's first emotion is overwhelming grief and guilt; he did leave his family unattended while he went to England to enlist Malcolm's aid. Then, when Malcolm says, "Dispute it like a man" (4.3.259), Macduff vows to get revenge on the fiend of Scotland, and Macduff's anger and rage are apparent. This is a pivotal moment in the play because we know that only a man not born of woman can defeat Macbeth, and this man is Macduff.
