Don't let greed eat away at your heart, and be humane and respectful to all. After the initial mistake, Creon and Keller's 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 he's 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 else's 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 Antigone's 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 son's fiancée. 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.
