Odysseus is a legendary hero in greek mythology. He was also important in the Trojan War and is notably the main character of "The Odyssey." in the Odyssey it is explained that Odysseus got lost on his way home from Troy after the Trojan War and is trying to make his way back.
Odysseus is a leader who shows examples of self-control, quick wit, and determination. In fact, a good many troubles during the voyage are caused by the crew themselves.
One of many islands that causes trouble for the crew is one called "The Island of the Lotus Eaters," where a group of people try and convince the crew to eat a lotus that will want to make them stay on the island forever. But Odysseus resists the lotus and has to drag his crew who ate the lotus back onto the ship, showing a great level of self-control.
Polyphemus is the next great challenge in the crew's way. Shortly after eating some of the crew and traping the rest in his cave, Odysseus makes a plan to escape, this shows his quick-wit and level-headedness in the face of danger.
The final example I'll use is what happened to Odysseus's crew on Circe's island. The witch Circe turns Odysseus's crew into pigs with magic, however, will a magical herb given by the gods, Odysseus becomes imune to Circe's magic and frees his crew.
In conclusion, Odysseus was a better leader than many people in the trojan war, but of course, not everybody is perfect including Odysseus. You could blame Odysseus for the greek god Posinen having a large disliking for the entire crew. But I would spread the blame to more then just Odysseus.
