In line 319 the chorus says, “Yet if he has a share of fear at all, his courage will not stand firm, hearing your curse”. I think this line means that if Oedipus is not completely sound of mind, he will fail in his endeavors. Word like these would have probably led to him having growing doubts about his own character. It also recognizes fear as a defining force in his life, with the trauma coming from the problems with his father. Usually in stories about Greek mythology, one’s own fear leads them down the path that faith has decided. One example of this was when Kronos ate his children because he foresaw them ruling over him. His actions fully lead to the gods rebelling against him and killing all the titans. One with courage within themselves and their family would be able to change fate and lead their own lives.
