The witches for example were very vague and did not tell Macbeth to do anything, even if they did it would be Macbeth’s decision to follow or ignore them. Anyone can come up to you and tell you to murder someone but unless they threaten you it’s your own decision to follow through what they say. If he really wanted to he could have walked away and not believed in a word they said. Same with Lady Macbeth, while she did try to “convince” Macbeth, it was his decision to agree or not and she could not have changed that unless she had a gun up to his head or forced him, which she didn’t. Finally fate is not the outcome of Macbeth’s decisions because it was caused by them and did not determine them. If I run around with ice cream in my hand and the ice cream falls it’s not fate’s fault, the fate of my ice cream falling was caused by my decision to run around with it and if I didn’t, then it wouldn’t have fell. Macbeth’s fate was directly linked to his actions as he did them by himself . If I murder someone and go to jail that was my fate but me going to jail wasn’t because of fate it was because I killed
