Ah, well, the thing is, Yui has been BLOWN UP TO PIECES and was still alive from that, and she had regenerated. She has also been stabbed multiple times, everywhere. Although, she knows that she could become a zombie, and unlike MacBeth (if I'm reading the summary correctly) she kinda wants to die. Although, she doesn't want to become a zombie.
Basic[VERY] breakdown of MacBeth
MacBeth is a Thane
Banquo is his friend
Three witches give both prophecies
MacBeth's says he will become Thane of Cawdor[which he isn't at the time of the prophecy, only Thane of (can't remember name)]
Banquo's says he will not be king but his children will be kings
MacBeth soon after becomes Thane
The current King decides they should celebrate at MacBeth's castle
MacBeth's wife convinces him to kill the King so that the witches prophecy shall be fulfilled
MacBeth kills King, then becomes King
He is a terrible King
He slowly goes insane
He hires assassins to kill Banquo and his son, but they fail to kill Banquo's son[Banquo is now dead]
MacBeth gets new prophecy
Witches tell MacBeth that he will not fall until Birnam woods come to Dunsinane hill[where his castle is]
That no man born of woman can kill him
and something else that is inconsequential to the ending
MacBeth is happy thinking that their is no way he can die
MacDuff, who suspects MacBeth of murdering the King plans with the one of the Kings sons[who ran after the king was murdered, making him look guilty]
They band together
They attack MacBeth's castle, hiding their numbers by cutting down the trees of Birnam woods to block his view[fulfilling the first prophecy]
MacBeth's soldiers give a half-assed fight because MacBeth is a terrible king and they don't want him in power anymore.
During the fighting MacBeth's wife kills herself out of guilt for convincing her husband to murder the King
MacBeth and MacDuff face off in a duel, and it is revealed that MacDuff was pulled from his dead mothers womb[second part of prophecy filled]
MacDuff kills MacBeth
The king's son takes the throne, all is happier.
Except sometime before MacDuff and the king's son make an alliance MacBeth has all of MacDuff's family, friends, and servants killed[this was to show MacBeth's ever decreasing sanity]
Their is the short of MacBeth, although the book isn't that long and its actually pretty good.
Does this help?
