Debate: people should be wary of joining Odysseus’s crew, for the reward is not worth the risk.

On the whole, it's probably not a smart move to sign up as one of Odysseus's crew. Although you get to experience more adventure than most people could ever possibly imagine, things get pretty hairy most of the time. Sea monsters, irate one-eyed giants, vengeful gods, and vindictive witches that turn you into pigs are just some of the occupational hazards that a voyage with Odysseus involves.
Violent death is an ever-present possibility, and though the captain of your ship is a brave, bold, and mighty warrior, there's only so much he can do to protect you. After all, as a member of Odysseus's crew, you're little more than a pawn in a cosmic game of chess being played by the gods. Everything is fated; it's been determined in advance that you're going to die, whether it's by being eaten alive by a Cyclops or a race of blood-thirsty cannibals or by being wiped out by a flash of lightning sent down by mighty Zeus. There is no reward, only risk. And if you do end up in Hades, you'll most probably realize like the noble Achilles that it's better to be a lowly slave on earth than to rule the underworld as the shade of a dead warrior.
On balance, it's probably best to stay at home. It'll doubtless be a lot more boring, but you'll live longer.
