how she helped Jason steal the Golden Fleece She betrayed her father and killed her brother These acts lead Creon to perceive her as cruel and heartless He fears that she will again use her power for evil Medea s history gives him enough reason to distrust her His decision to exile her comes from his knowledge of her crimes His suspicion is based on truth not on false belief Fear of Magic and Tricks Creon fears Medea s magic powers He knows she has the skill to harm through spells and poisons He believes she can destroy even from far away Medea herself says I m dangerous to enemies but well disposed to friends This line proves Creon s fear correct He knows she is clever proud and cruel when betrayed His fear of her wisdom and revenge makes him act quickly and send her away from Corinth Thus Creon s suspicions against Medea come from fear truth and experience He knows her anger and her magical power Euripides shows that his fear is wise though it cannot save him from death
