Macduff goes to England to seek help in his quest to overthrow Macbeth, who has usurped the throne of Scotland. After the murder of King Duncan, Macduff becomes suspicious of Macbeth’s rise to power and fears for the safety of his family and country.
His journey to England is primarily to find Malcolm, Duncan’s son, who has fled to England after his father’s death. Macduff believes that by aligning with Malcolm, he can gather forces to challenge Macbeth’s tyranny. This is significant as it shows Macduff’s loyalty to the rightful heir and his commitment to restoring order in Scotland.
Moreover, Macduff’s trip to England represents his role as a noble character who takes action against the corruption and moral decay brought about by Macbeth’s reign. It also sets the stage for the eventual confrontation between the forces of good, represented by Macduff and Malcolm, and the evil that Macbeth embodies.
