According to Aristotle, a tragedy is a form of theater that replicates a solemn action with the intention of stirring dread and sympathy in the viewer. Sophoclesí Antigone and Arthur Millerís All My Sons both fit into this category. Both stories consist of a tragic hero, Creon and Joe Keller in this instance. According to Aristotleís Poetics, a tragic hero is someone not all good or all bad, and whose downfall is caused by a tragic flaw or "hamartia". Later the hero comes to a realization of their flaw, which usually comes too late for them to redeem themselves. Creon and Keller are both tragic heroes that fit into Aristotleís model, whose downfall is caused by greed, excessive pride and a belated recognition of their flaws. The misfortunes that Creon and Keller bring upon themselves teach us to avoid their mistakes, which is the purpose of all tragedies.

Selfish greed for material wealth and power is what causes Creon and Keller to make the serious mistake that ultimately ruins their lives. Keller ships out the cracked engine heads because his factory would bankrupt otherwise. He wanted money, a house, and a good, wealthy life for his family. His intentions are good, but he is wrong putting others at risk for his own prosperity. "Chris, I did it for you, it was a chance and I took it for you. (59)." This shows Kellerís selfishness in sacrificing other peopleís lives for his sonís career. Likewise, Creon decides to kill Antigone because he wants to appear as the all-powerful ruler of Thebes. He feared that any pardoning of Antigone would detract from his power as king. These examples show us that as common people, we should always put others into concern when making decisions. Donít do things out of selfishness that may hurt others, because it will eventually get back at you, whether itís just remorse or some kind of physical punishment. Donít let greed eat away at your heart, and be humane and respectful to all. After the initial mistake, Creon and Kellerís attitude toward what they had done brings out one of their most significant characteristics.

Pride is the major flaw of both Creon and Keller, robbing them of the chance to make up for their bad deed. Keller ships out cracked plane and refuses to admit to his mistake because he is too conceited to do it in front of his family. Since heís the father, he felt he had more wisdom because of his age. As for Creon, he cannot not put his pride down and pardon Antigone because if he the king issues an edict, then it must be obeyed. This shows that Creon wishes to appear as the supreme ruler of Thebes. Furthermore, he would not consider anyone elseís suggestions toward the matter. "Men that we are, must we be sent to school to learn discretion of a boy like this. (27)." He also rejected Antigoneís beliefs towards what she had done. This demonstrates that Creon is too proud to listen to anyone that he considered inferior to him, like his son and his sonís fiancťe. We learn from the heroes not to let arrogance possess your soul, because excessive pride can cause people to lose good opportunities to better themselves. Anyone can teach a good lesson, no matter of their age or gender. In the case of making a mistake, you should try your best to make up for your deed. It takes the heavy lead off the conscience. Because Keller and Creon give themselves reasons for not admitting to their mistakes, they are strongly convinced that they are correct until the recognition.

Keller and Creon both refuse to face their mistakes until someone points out something that makes them feel like they can no longer go on with their old beliefs, which is too late. This is what eventually causes the recognition. Keller believes that he is right in shipping out the cracked engine-heads, because he did it for the well being of his family. When he has the argument with Chris, he believes that Larry would be on his side. "Goddamn, if Larry was alive he wouldnít act like this. He understood the way the world was made. He listened to me. (63)." This example shows that Keller
