Macbeth is building up a case that Banquo has caused injury to the murderers, so the murderers, in attacking him, are fulfilling some kind of moral duty. So he outlines the injuries the murderers have suffered and the First Murderer says, perhaps a little ironically, "You made it known to us." As in, we didn't know that we were so hard done by until you told us.
Macbeth responds by asking, "Do you find your patience so predominant in your nature that you can let this go?" This is a roundabout way of calling them cowards, the kind of guys that people can insult with impunity.
The Murderer responds "We are men, my lord." As in, "What do you think? Any real man would respond to such offences."
This is all part of the "Real Man" dialogue that runs throughout the play. Remember Macbeth in Act 1 scene 7: "I dare do all that may become a man; who dares do more is none."
If by Macbeth's murderer you mean Macduff (although it wasn't murder because he killed him in a fair fight) he aligned with Malcolm the elder sun of King Duncan.
It means that Macbeth is so paranoid he doesn't even trust the murderers.
The "filthy witness" which Lady Macbeth talks about washing from Macbeth's hands is, of course, Duncan's blood. "Filthy" because it is dirty and smells unpleasant. (Have you ever been covered in blood?) "Witness" because its presence on his hands marks him as the murderer--it testifies against him.
"Dolofonos" in Greek means "murderer" or "killer."
murderer
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
It means you have to give him a Dirty Sanchez first
I am not sure which character you mean: Siward, an English general, or Seyton, one of Macbeth's servants.
Do you mean Macbeth the person or Macbeth the play? Because it is possible to like the play and not like the person much.
That depends on who you mean by the guest, and when. In Act 3, Scene 1, Macbeth calls Banquo "our chief guest." Macbeth is the one who dismisses Banquo after that conversation, saying "Hie you to horse. Adieu, / Till your return at night." If you mean the guests at the dinner party in Act 3, Scene 4 (after Banquo has been murdered and is appearing at the dinner as a ghost), Lady Macbeth dismisses them by saying "At once, good night. / Stand not upon the order of your going, / But go at once."
Assassin, Killer, Murderer.
