Answer:
Revenge and Character Flaws
Step-by-step explanation:
Generally, many characters cause problems for their flaws. Odysseus reveals his own name to the Cyclops because he wanted Polyphemus to know who had tricked him, which cause major problems later on. Also, Penelope doesn't ever send the suitors away. She promises them that after her mourning period, she'll choose someone to be her new husband. She doesn't intend to betray Odysseus, though, but it seems that she enjoys the attention that she is receiving.
Although it does talk a lot about human nature in many ways, the idea of revenge is frequently shown in the story. Odysseus wants revenge against Polyphemus, who then wants revenge against Odysseus. Later on, Odysseus eventually also kill all the suitors who were at his house taking advantage of the fact that he was absent.
