The witches' predictions that he will be the father of a line of kings.
One example of dramatic irony in Act 3 of Macbeth is when Macbeth decides to have Banquo and Fleance killed in order to secure his throne, without knowing that Fleance will escape. Another example is when Macbeth expresses concerns about not being able to enjoy his newfound power, unknowingly foreshadowing his descent into paranoia and guilt.
In the last scene of MacBeth, MacBeth is killed offstage by MacDuff in their brawl. After their fighting goes off stage MacDuff returns to the stage with MacBeth's head. This event is very similar to the beheading of Macdonwald the traitor by MacBeth early in MacBeth.

In 'The Tragedy of Macbeth', I found Fleance and Macduff worthy of pity. Fleance was so young to lose his father in such a despicable way. He may not have been able to see the heinous deed. But he had to have figured out what was happening. Undoubtedly, he subsequently heard the gory details of the throat-slitting end to his father. Also, he had to make the difficult choice of saving himself and his father's family line, over not letting his father die alone. Macduff was pitiable, because he lost his entire family. It must have been horrible to learn of their bloody, painful end by brutal, savage murderers. Somehow, he had to keep himself from falling to pieces long enough to organize the successful overthrow of Macbeth.
