While fate can be determined by that of ones destiny or that of a person's free will, the outcome of the matter is generally the same. The only difference between free will and destiny is in how the subject goes about claiming its specific fate. Macbeth's fate was determined by both destiny and free will, but in the end, the life he had chosen was made more evident by which path he had taken. Macbeth's ambition was the only element that spurred him further into his decent to evilness. The outcome of Macbeth's fate was not determined by destiny, but by that of his own free will. .
Chance is an element that includes both destiny and free will. Macbeth's first wrongful act which was decided by his free will was to listen, and take what the three sisters had told him into consideration. At the beginning of the play, Macbeth's actions are more likely determined by chance than anything else. In act one of Macbeth, he is quoted as saying to himself, "If chance will have me King, why, chance may crown me,/ Without my stir" (Shakespeare, I, iii, 143-144). Macbeth knows that he is a grandson to a king, and therefore he has a legitimate claim to the throne, and also knows that disease could easily speed up his arrival, but Macbeth decides to eventually take matters into his own hands when he realizes that "chance" will only be rewarded with his aid. This is why he decides to go through with the murder of King Duncan. Therefore, Macbeth's state of chance was further pursued by his own free will which first led to the murdering of Duncan. Also as Macbeth is ready to commit acts of murder upon the throne, he calls upon the darkness to hide himself from the wrongful doings that he is about to willfully commit. "The eye wink at the hand; yet let that be,/ Which the eye fears, when it is done, to see" (Shakespeare, I, iv, 58-60). Thus, the previous quote displays Macbeth's acknowledgement to the acts he is about to commit and further trying to bury himself in his own pit of despair by masking his dirty deeds.
