In Parts 1 and 2, we have seen bravery on the part of Odysseus as he faces countless monsters. What is similar about the ways he faces danger for...

Odysseus is really brave in the face of danger, and he is willing to encounter danger himself for good reason.  When he forms his plan to kill the Cyclops, Polyphemus, he knows the risk of being one of the men to plunge the stake into the Cyclops' eye (as they have to stand on the monster in order to accomplish this), yet he insists that he be one of the men to take this risk....

Odysseus is really brave in the face of danger, and he is willing to encounter danger himself for good reason.  When he forms his plan to kill the Cyclops, Polyphemus, he knows the risk of being one of the men to plunge the stake into the Cyclops' eye (as they have to stand on the monster in order to accomplish this), yet he insists that he be one of the men to take this risk.  Further, when he and his crew land in Aeaea, he confronts Circe -- a dangerous proposition -- even though he knows that she has incredible powers, because he needs to save his men.  Then, after Calypso releases him, he sets out -- alone, on a raft, in the sea -- despite the fact that he has deeply angered Poseidon by blinding his son, Polyphemus.  He is quite willing to put himself in danger when the benefit seems to outweigh the risk.

Odysseus is actually more willing to endanger himself than he is willing to endanger his crew.  When their ship approaches Scylla, he arms himself so that he can try to kill her before she has a chance to attack his men.  Further, when their ship passes the Sirens, he stops his crew's ears with wax so that they will not be tempted by their song.  He has them lash him to the mast so that he, alone, will hear and be tortured by the song; his crew will not have to bear it.  Even in the land of the lotus-eaters, when the three scouts do not come back to the ship because they've eaten the lotus fruit and now no longer want to return home, Odysseus goes himself to physically force them back, risking his own safety instead of leaving them behind or endangering another crew member.

Ultimately, Odysseus is very willing to face danger to preserve himself or his crew, and he treats them -- for the most part -- generously and kindly.  He sincerely mourns the loss of each man.
