A hero is someone who is a brave leader, and who is always willing to help others,not for their own pride but for the good of being a kind person.
Odysseus does not portray the role of a leader
Odysseus was not a hero here because he put his men in a dangerous situation for no reason. He was being reckless and lost 6 men because of it.
Odysseus sent three of his men to go see if the Lotus Eaters where friends or enemies. Those three men end up wanting to stay and live on the island with the Lotus Eaters. Odysseus drags his men onto the boat and forces them away from the island.
Odysseus came up on a lush deserted island, however he was interested in the cyclops, so he brought 12 of his best men up to the cyclops cave. The men ate the cyclops's cheese and threatened him, but the cyclops ate 3 of the men. Later, Odysseus got cyclops drunk and stabbed his eye, and then escaped hiding under sheep so the cyclops can't find them. When Odysseus got the boat he yelled to the cyclops all his information and cyclops cursed his journey.
Odysseus sends his men to go check out circe, but she ends up getting them drunk and turning them into pigs. Odysseus then has sex with Circe so she'd turn his men into men again. Circe then asks them to live with her, which they do for almost 2 years. Then when they decide to leave, Circe sends them to the underworld.
