What is an example of odysseus' curiosity?

nobody except Odysseus wants to go to the island of the cyclopes

the events that occur on the island are therefore as a consequence of his curiOSity adn it can be argued that he is therefore responsible for the death of his companions who are eaten by Polyphemus

also how he wants to hear the sirens song

He is curious to figure out just who among his servants have stayed faithful all these years -- so he will know who to rely on in the upcoming battle with the suitors
