I think that a joint obituary of both might be appropriate. It will be essential, that at some level, the obituary discusses the level of responsibility each held in the descent into moral depravity that overtakes each. Certainly, there can be discussion of how each is, to a certain extent, devoted to the other. I do sense that there is a sense of love between them at the start of the drama in that both are driven to please or appease the other. Lady Macbeth would not have encouraged Macbeth unless she felt that her stock was interlinked in his own. Certainly, Macbeth listening to his wife indicates some level of devotion. I would also point out how their moral depravity ends up causing a sense of havoc on their marriage, for as each murder is committed a further and wider void becomes more present in their marriage.
If I were writing obituaries for these people, I would first be sure to mention the ways in which they died. (I would be writing as a news writer for a newspaper -- not someone trying to eulogize them).
I would then mention the things that made them notable. I would talk about how Macbeth was an honored warrior until he went crazy with ambition (maybe I'd say he hallucinated the witches). Of course I would have to mention all the terrible stuff he did as king.
For her, I would talk about her having been a great support to him, but also say that she had helped bring him down because she was ambitious and egged him on.
For Macbeth and Lady Macbeth, I would have written obituaries like the following:
After much of chaos, innumerable killings, and a long-time torment of the Scots, the age of the "butcher" is finally put to an end. Macbeth has been slain by Macduff, the Thane of Fife. Macbeth is lost in the battle against the allied troupe led by Prince Malcolm, who is going to succeed the throne very soon as the king.
The worthy "Gentleman" Macbeth, once, was a brave warrior and very favourite of King Duncan. It is he for whom the Scots achieved victory against the terrible war against the Norwegians. Nonetheless, it was the same Macbeth who killed Duncan with his own hand. It was Macbeth who is responsible for the death of Banquo, Lady Macduff and the innocent son of hers. More than that his intoxicating venomous ambition made him so greedy that he was almost blindly driven by the gang of Hecate. He lost the sense of humanity and morality out of his greed. And, at the end, he has reaped what he sew.
This man will remain alive as a legend, but not as a famous and virtuous one, but as a notorious brutal tyrant in the minds of the Scots for good. Thus is the finishing of Macbeth. After all, the people of the country are relieved now.
*In case of writing obituary on Lady Macbeth, I'd like to assume that, still, Macbeth is alive.
- Lady Macbeth:
The "fiend-like" queen, the collaborator and partner of Macbeth, Lady Macbeth has committed suicide.
Lady Macbeth, as it is known from a reliable source, had been insomniac for many a days, which is supposed to be an outcome of her sense of guilt. She could no longer bear what she along with her husband did so far, and finally, she gave up. Almost all the Scots are pretty sure that the queen is, to a great deal, responsible for the present chaotic situation of the country. So, it is said like- she has got what she deserved.
How much the fact of Lady Macbeth's death would influence Macbeth, the tyrant, can not be said certainly. But, it is very true that, he has lost one of his greatest powers with his wife's death.
