No, I don't believe Lady Macbeth was an evil person, just an ignorant who allowed greed posssess her. I feel that the whole idea of becoming a queen got to her headand froze out her heart and conscience. She let her greedy ambition run away with her soul, leaving her very cold ad thoughtless. After Macbeth killed Duncan in the well planned manner she came up with, Lady Macbeth showed no guilt. Then as she saw how being queen wasn't that great and how it destroyed Macbeth, Lady Macbeth became so overwhelmed by the realization of her sin that she went somewhat mad and killed herself.
