Final answer:
The quote from Macbeth suggests the major theme of fate versus free will, as it relates to the prophecy given to Macbeth and the choices he makes which lead to his downfall.
Step-by-step explanation:
The quote "All hail, Macbeth, thou shalt be king hereafter!" from Shakespeare's Macbeth, embodies the major theme of fate versus free will. This theme is explored through the prophecy given to Macbeth by the witches and his subsequent actions. The idea of fate is presented through the inevitability of the prophecy's fulfillment, while free will is demonstrated by Macbeth's choices that lead to his downfall. Macbeth's reaction to the witches' prophecies can be seen as his internal struggle between letting fate unfold and taking action into his own hands to ensure the outcome.
