Macbeth is brutally killed in Act Five. What other event in Act Five does this parallel in Shakespeare's Macbeth?

In Act Five, of Shakespeare's
Macbeth, the tyrant Macbeth, who murdered Duncan and others, will
be killed by Macduff, who has vowed to take Macbeth's life to avenge the death of his
family and servants at the King's command.

The other event
that parallels Macbeth's death, but takes place in scene five, is Lady Macbeth's death.
She, too, was complicit in the murder of Duncan, but the guilt of what she and her
husband have done has driven her mad. She has taken to sleepwalking and reliving the
murders, and cannot sleep without a light next to her bed. Lady Macbeth ultimately kills
herself.

Upon hearing of her death, Macbeth notes that she
would have died sooner or later. I think he has become so numbed by his tyranny, that
even the death of the woman he loved so much at the start of the play fails to rouse any
real sorrow at her passing.
