Medea on Trial

Medea is an anti-hero because she became consumed by hatred and eventually killed 4 people, two of them her own children. At the beginning of the story, she states that she hates her children as well as Jason, their father. The children are like reminders of her traitorous husband to her. As the tale went on, her madness grew stronger. Anti-heroes digress as time goes by. She plotted how she'd kill Creon's daughter the princess using a poisoned golden diadem and dress. Her motives were out of her own personal gain of seeing Jason in pain. In fact, she even kills her own two children. No person in their right mind would kill their kids. These events Medea did caused her fall to an anti-hero as well as a break in tradition at the time.
Greek tradition in her time was that women's roles were to have kids and do chores, lacking a say in their relationship with their husband. Jason left Medea but Medea couldn't legally do anything about it. Her angry demeanor to the situation does speak out against her status as a woman. Naturally, a woman would be very angry if their husband cheats on them. However, the way she acted was unjustifiable. Jason's wife-to-be dies due to Medea's poisonous gifts along with Creon who got stuck to his daughter. Also Medea stabs her own children before she fles from Corinth. There is a fine line between anger and causing havoc with it; Medea crosses the line. Therefore, she is guilty of planned murder and being an anti-hero.

Jason the Anti-Hero

As Jason and the Argonauts progressed, it became more clear that Jason was an anti-hero due to his selfishness, but one moment stood out in particular. Many years ago, his father the rightful king was killed by King Pelias. Fast forward to the quest for the Golden Fleece when Jason got into a sword fight with Acastus over how to approach King Aeetes about the Golden Fleece. Jason's greed for the throne and the Fleece got in his way and he wanted to kill Acastus, who was son of King Pelias. He wanted revenge for his father's death. Although Jason forced Acastus to jump overboard, Acastus was still alive. Normal heroes weren't greedy, fought against friends, or out for revenge. However Jason was as well as Two Face, also known as Harvey Dent from The Dark Knight.
Harvey Dent (Two-Face) was the district attorney of Gotham. He wanted to take down the Joker, however that changed when his girlfriend Rachel Dawes was killed from a bomb explosion due to the Joker. Death turned both him and Jason to darker heroes. After that, he wanted dead the people he deemed responsible for the death of his girlfriend. That was simaliar to how Jason wanted Pelias dead. In fact, he attempted to kill James Gordan, Gordan's son, and Batman with the fate of their lives up to a single coin flip. On the other hand Jason got into a fight with the son of King Pelias, Acastus. Both of those heroes were driven to digress by their lust for revenge and selfish wants.
