He used the concept in Othello as well - Iago used Guilt to deceive Othello against Desdemona
Both Macbeth and Lady Macbeth are necessary for the play. Neither would have murdered Duncan without the other. Shakespeare also wanted to explore the effects on their relationship of the guilt they experience after the murder.
Fate and fatalism--to what extent do we have control of our destiny? Guilt--what is the effect of guilt? Legitimacy of succession--although Macbeth's succession was legitimate by Scottish law, the English would not view it that way. Moral decline--how one evil act makes one inured to other evil acts.
Since you have added this question to the William Shakespeare catedgory, you won't be surprised to find that these three plays were all written by William Shakespeare, the most famous playwright ever.
Macbeth was not a fictional character made up by Shakespeare. He was based on a historical character, although he is not in any way like the real historical Macbeth. Shakespeare took most of the story of Macbeth from the history book Holinshed's Chronicles which contains most of the events shown in the play. Shakespeare did develop the character of Macbeth found in Holinshed, but he did not invent him.
My guess it is Chloral Hydrate or some other form of Knockout drops. If you stop and think, this is adding drug abuse- surely a deliberate misuse of these products- to the Shakespeare canon- and it was only suggested by the remark ( Dagger of the Mind) in Macbeth- which Polanski took ( he directed the Macbeth film) to make tie-ins to Droggs!
Shakespeare's tragic plays include Romeo and Juliet, King Lear, Othello, Macbeth, and Hamlet. Other classical tragedies include Euripides' Alcestis, The Medea, Hippolytus and The Heracleidae.
That quote is from the William Shakespeare play Romeo and Juliet.
That word does not appear in Shakespeare's Romeo and Juliet. Maybe it is in some other one.
Shakespeare's most popular play is Romeo and Juliet. It is a tragedy that was written some time between 1591 and 1595. Shakespeare is also famous for having written many other popular plays. These include A Midsummer Night's Dream, Othello, and Macbeth.
Macbeth is a tragic hero. In the beginning of the play the audience sympathizes for Macbeth and view Macbeth in the right when he kills Duncan. By the end of the play however views have shifted and Macbeth is seen as a villain because he has used his power for bad. In Shakespeare's plays the villains are not usually tragic heroes.
Shakespeare shows many different kinds of marriage. Romeo and Juliet are passionate, the duchess in Alls Well clearly had a companionate marriage. Petrucchio and Katarina (in Shrew) fight to a standstill, Beatrice and Benedict (Much ado) seem to fight for the pleasure of it. Macbeth and Lady Macbeth are toxically in love with each other (it is love that drives Macbeth to murder), Imogen and Posthumus (Cymbeline) use their love to carry them both through extreme tribulation. I cannot think of a single aspect of marriage which Shakespeare does not cover somewhere or other. Perhaps your teacher is cleverer than I am.
"That which we call a rose by any other name would smell as sweet" are words spoken by Juliet in William Shakespeare's Romeo and Juliet.
