What are the warring feelings within Macduff? How does Macduff show his humanity in his reaction to Ross’s news? impact on the audience?

Macduff keeps asking Ross how his family is doing. I think that Macduff is aware of the danger he has put his family in by leaving. Macduff mourns and cries over the death of his family. Malcolm tells Macduff to, "Dispute it [the murder of his family] like a man" in Act 4:3.223. Macduff responds the very next line with: I shall do so. But I must also feel it as a man.
