He is already guilty enough from killing Duncan and doesn't want to have more guilt by killing his friend Banquo. he think that the murderers would tell others that macbeth is the one who kill people
The play doesn't say so, but it is a plausible interpretation. Macbeth wants to be safe; it wouldn't be safe having these cutthroats who know he was involved in Banquo's death hanging around.
At first he believes he does not have to because he has already become the thane.
To ensure the murderers will 'dispatch' (kill) Banquo, Macbeth tells them, 'Banquo was your enemy, So he is mine'. Basically, you do not like Banquo and therefore, neither do I. So I encourage you to kill him. It was very manipulative of Macbeth to say this to the murderers. He also threatens their manhood, compares them to dogs and applies various other tactics so he can feel certain they will kill Banquo and Banquo's son, Fleance.
Ya he hablado con ella. (I have talked with her already) Or...Ya hablé con ella. (I talked with her already.)
Macdonweald. Macbeth split him from the nave to the chaps. Don't say the Thane of Cawdor; the text does not say he was captured by Macbeth and it wouldn't make any sense to say he did.
did you think about what we talked about in my car.
It doesn't say that anywhere in the play. Also, Macbeth is a male.
In Macbeth, the three witches are referring to Macbeth when they say "Something wicked this way comes." They are speaking about Macbeth as he approaches them, indicating his dark and villainous nature.
You would say "Jack and Jill talked briefly."
Macbeth get told by the witches say "hail thee, thane of glamis" which he already was then "hail to thee thane of cawdor" which he was but he hadn't been told because he had been in battle then "thou shalt be king hereafter"
Macbeth
The true reason is unknown and only inferences can be made. It is possible that MacBeth feared that the other two murderers would not do as he told them and MacBeth sent a third murderer to keep and eye on them. He may have also thought that two murderers alone would be unable to carry out the killing of Banquo and after realizing the fact he decided to send a third. If this was the case then MacBeth was partially right because although the murderers were able to kill Banquo his son, Fleance, escaped. Also, there's a theory that Macbeth himself was the third murderer
