Attention Shakespeare fans: All you need to know about MacBeth

[Aristus]

9. Excellent! But I have to disagree with you on one point:

"Macbeth has no internal conflicts before he meets the witches,
and he has none to speak of during the final duel with Macduff."

This is just my opinion, of course. But consider:

"Of all men else I have avoided thee. But get thee back, my soul is too much charg'd with blood of thine already."

He regrets killing Macduff's family, but he is prepared to kill Macduff to secure his own power.

"Get thee back." This may be a warning, and also a form of self-protection. He hasn't yet learned that Macduff was from his mother's womb "untimely ripp'd", but he has seen the other prophecies come true, so he has no reason to expect that the "no man of woman born may kill thee" prediction will hold. Indeed, in the next few lines, he mentions this to Macduff, but with the air of a man trying to convince himself, rather than who he is talking to; whistling past the graveyard, as it were.

I think he's conflicted like crazy...
