The story of Macbeth takes place in Scotland in the 11th century. Shakespeare has written a tragedy about how a Scottish nobleman (Macbeth) who plots the death of the King in order to become King himself. Due to the tragedy aspect, things do not really go according to plan!

"For brave Macbeth" (I, 2, 16) is used by an army Sergeant to describe his actions in the battle. Such phrases as "worthy gentleman" (I, 2, 24) are used by the King. This shows that Macbeth really was a hero, as such a compliment from the King was considered a great honour.
The first murder Macbeth commits, is that of King Duncan. This murder, was inspired' by the witches. The witches first meet Macbeth while he and Banquo are riding by.

Hail to thee, thane of Cawdor" (I, 3, 49). At this point in the play Macbeth had just become thane of Glamis, and the thane of Cawdor is still alive and well. Next, the witches greeted
Macbeth as the King of Scotland: "All hail, Macbeth! That shalt be King hereafter" (I, 3, 50).

I believe that this is the point in the play where Macbeth starts to think as a villain. If the witches had never greeted him as King on Scotland, then he would probably...
