In Act 1, scene 5 Lady Macbeth says “look like the innocent flower but be the serpent under it” Shakespeare is referring to the serpent which is an allusion to the Bible ad the story of Adam and Eve where the serpent (representing evil) persuades Eve to eat and give Adam an apple from the forbidden fruit tree. This simile means that Lady Macbeth wants Macbeth to come across as a loyal and great leader but remain cautious and hide the evilness inside him. This manipulation by Lady Macbeth towards Macbeth causes inner conflict about what is right and wrong and he struggles with his personal loyalty to King Duncan and also to his wife Lady Macbeth.
Lady Macbeth caused further conflict within Macbeth as shown with the quote in Act 1, Scene 7 “and you shall put this nights great business into my dispatch.” Lady Macbeth is telling Macbeth just leave it all to me. I will do all the organizing if you can just pluck up the courage to kill King Duncan. Her planning of this would make the murder of the King seem easier for Macbeth, which is adding to the conflict Macbeth has whether or not to kill King Duncan to inherit the throne.
By the time we reach the end of Act 1, Scene 7 we see a significant moment in the play because a the end of this scene is when Macbeth starts to lose the fight within himself causing the ruin of his understanding and therefore bringing out the evil in him. Shakespeare
