Who Is Responsible For Macbeth's Downfall

To what extent is Macbeth responsible for his own downfall?

The tragic downfall of Shakespeare’s Macbeth can be attributed to his forceful ambition which leads him to commit terrible deeds, selfish greed and weakness that allows him to be easily manipulated. These influencing factors are nourished and encouraged by the three witches and the deceitful Lady Macbeth. Macbeth’s actions of murdering innocent children and women and his damning act of genocide show that he is primarily responsible for his own demise.
Macbeths ‘ambition which overleaps itself’ leads him to commit heinous crimes that show his depravity and ultimately leads to his downfall. Macbeth lets his ‘ambition’ rule him and his decisions; his ambition comes before everything
The power that he has ‘played most foully for’ allows him to do what he wants as he thinks of it stating ‘the very firstlings of my heart shall be the very firstlings of my hand’.

This shows his weakness in character, because his mind is conflicted; yet, his decisions, which result in a great tragedy, are his own but are heavily influenced by his scheming wife. At the end of the play, the moral weaknesses of Macbeth are totally revealed along with his mental weaknesses. He is no more the worthy warrior of battle fields. Indeed, he is a paranoid king who copes with guilty hallucinations and tries to secure himself by killing innocent people. For example, in the banquet scene, he sees the ghost of Banquo whose death was ordered by Macbeth and the guests start to suspect his mental health and talk unpleasantly of him.
