The witch in the 'Macbeth' hailed with this words. To be scientifically true, Witch never exists. But it indeed exists in our mind. The fate of Macbeth is well known. Ambition leads Macbeth to the destruction. Being a reader I have an enquires...Macbeth is only responsible for his destiny? Can Lady Macbeth be ignored or she must be introduced to complete the story? Yes, Lady Macbeth is one of the central characters. I have no idea whether Macbeth's ambition was provoked or it was initiated by Lady Macbeth.
Apart from my quest to know Macbeth more deeply I want to express that I need this answer to solve a puzzle in my personal life which has become no better than a hell to me.
I urge to those whoever reading this post, to reply with a precise and compact answer.
