macbeth

• Lady Macbeth goes from calling Macbeth 'worthy cawdor' to 'coward' (Lady Macbeth Act 1)


  -
• 'a good and virtuous nature may recoil / In an imperial charge. But I shall crave your pardon - Malcom to Macbeth

  -
•  “all the perfumes of Arabia will not sweeten this little hand” 


  she portrays the weight the metaphorical blood has on her conscience, which entices the idea of guilt. The use of the hyperbole establishes her changed attitudes, as she had previously manipulated Macbeth though phrases such as “a little water clears us of this deed”, a euphemism for the regicide that had not affected her then but seems to now.
• 'perfumes of arabia'


  the description of “perfumes of Arabia” can also connote wanting to be cleansed of sins, such as through religious sacraments such as anointing, which is done with oil. The perfume she mentions may not presents just the fragrance which will give her temporary salvation from the memory but rather her wanting redemption from God through undergoing a holy sacrament such as the anointing, which will rid her of the guilt she harbours due to the regicide plaguing her mind.
