realisation for macbeth that he has been tricked
"and be these juggling fiends no more believed, that palter with us in a double sense"
prophecies that once gave him confidence have deceived him
"juggling fiends" are the witches
prophecies are supernatural as they are knowledge of the future which is beyond the human realm of understanding
they are deliberately ambiguous and misleading
macbeths downfall is directly linked to his belief in and reliance on the supernatural prophecies
