In a well-written response, establish where you believe the turning point is in Macbeths mindset that turns him from an ambitious but loyal individual to a cold-blooded murderer? Firstly identify who he seems to be (add support); secondly who we believe him to be (add support) and thirdly provide / explain where that line between moral and immoral behaviour becomes blurred, confused, or quite simply no longer relevant for Macbeth.
