Can you please edit my thesis for my essay? Thank you. The Prophecies in Macbeth by Shakespeare provoked Lady Macbeth and put the idea in her head which caused her to push Macbeth to carry out horrible acts and lead both of them to their tragedies. Lady Macbeth was influenced by the witches, she made Macbeth feel like he had to commit these acts because of the prophecies. Macbeth then completely shut Lady Macbeth out and took over.
