Guilt is a very powerful emotion that an individual always feels in relation to others and has its genesis in the wrong done by one person to another. The two important literary works Macbeth and The Kite Runner, although invented centuries apart, revolve around an incessant sense of guilt felt by the central characters who are Macbeth and Amir, and the ordeal they had to face due to the psychological difficulties and practical consequences of such guilt. In the Shakespearean tragedy Macbeth, although Macbeth manages to kill the Scottish king Duncan to actualize the prophecy of the three witches, the guilt resulting from such nefarious acts and intentions continues to foreshadow Macbeth's life throughout the plot. The moment Macbeth approaches Lady Macbeth with his hands dipped in Duncan's blood, his deep guilt exudes as he says, "I thought I heard a voice cry 'Sleep no more; / Macbeth kills sleep ( 2.2.45-46)”. Thus, from this moment on, Macbeth is strongly affected by an inexorable and continually nagging sense of guilt that leads him to perform strange and suspicious acts and ways. Yet, Macbeth repeatedly interprets his guilt as a sign of cowardice and continues to shed more blood to consolidate his control over an ill-gotten throne The torment and anguish inherent in these lines which are steeped in the seeds of guilt eventually transform into a real sense of. guilt and shame that continues to torment his soul. As the play progresses, the consequences of Macbeth's deep sense of guilt assume such gigantic and vivid proportions that they are personified in the apparition of Banquo who materializes before Macbeth, while sits in the middle of the card. ....of Amir in his childhood not only severely colors his relationship with Hassan, whose innocence he failed to protect from the evil and domineering Assef, but this guilt continues to remain with Hassan as he moves to America and a new life begins. In the end Amir chooses to redeem himself by choosing to protect Hassan's son, Sohrab. The guilt that in a certain sense separated Amir from his childhood friend manages to reunite him with Hassan, albeit in a different way. In this way, the two works Macbeth and The Kite Runner not only present humanity with the immense power and potency of guilt, but also emphatically reveal the possible consequences of guilt that can be traced back to an evil act or an act of cowardice or betrayal . These two works expose the psychology of guilt in a very vivid and well-worn way, which explains their charm and the human interest they arouse.
