Macbeth Quote Analysis

After hearing that no one born of woman can harm him, Macbeth concludes he need not fear Macduff but immediately decides to kill him anyway.

Macbeth's rhetoric collapses in on itself: he asks 'what need I fear of thee?' then instantly pivots to 'But yet I'll make assurance double sure,' revealing that the prophecy has not actually made him feel safe—it has only given him a new rationale for murder. The phrase 'take a bond of fate' is absurd: you cannot force fate to guarantee anything, but Macbeth speaks as if killing Macduff will lock fate into place, showing his desperate need to control what the prophecy already promised was secure.

Use this to argue that the prophecies do not comfort Macbeth—they deepen his paranoia. Even when told he is safe, he immediately seeks 'double' assurance through violence, showing that tyranny is driven not by strength but by an insecurity that no amount of killing can ever satisfy.
