Macbeth is evil

      I think he is evil in the final analysis. Just because the witches give him a prophesy, does not mean he needs to act. He kills wantonly, sometimes when it doesn't even necessarily benefit him at that moment. While there are many plausible 'excuses' for some of his actions, killing for power is its epitome.Blood is everywhere in Macbeth, beginning with the opening battle between the Scots and the Norwegian invaders, which is described in harrowing terms by the wounded captain in Act 1, scene 2. Once Macbeth and Lady Macbeth embark upon their murderous journey, blood comes to symbolise their guilt, and they begin to feel that their crimes have stained them in a way that cannot be washed clean. “Will all great Neptune’s ocean wash this blood  clean from my hand?” Macbeth cries after he has killed Duncan, even as his wife scolds him and says that a little water will do the job.Blood symbolises the guilt that sits like a permanent stain on the consciences of  Macbeth.
