Most evil

I think the most evil character in Macbeth has to be lady Macbeth. Lady Macbeth is very sly. She pressures Macbeth into doing the deed and then badgers him to hide what he has done. Macbeth killing Duncan is totally out of Macbeth's character. It was Lady Macbeth's original idea. She is very conniving and seems to get her way. I think that she ultimately isn't worried about weather Macbeth comes into power. Instead she is worried about her own ranking in the world. This deed will advance her and Macbeth alike.
