The motif of evil is seen throughout the play, Macbeth, written by William Shakespeare. The motif is used to help the theme of darkness along, making it seem more sinister. Along the way, many of the characters use evil to their own ends, such as Lady Macbeth, in the way she helps in the assassination of King Duncan.
