Both of them threaten to kill both Odysseus and his crew. However, there is no way past except to sail past at least one of them. Charybdis is the bigger danger, as it threatens to destroy the entire ship.
Charybdis is a giant whirlpool and Scylla a monster that feeds on men; it is the question of certain doom versus losing only a few of his crew.
Circe warns Odysseus of the dangers in store for him and his crew on their journey home. These dangers include the Sirens, Rovers, Scylla and Charybdis, and Helio if his cattle are slaughtered.
Odysseus uses intelligence during his encounter with Scylla by strategizing to minimize his losses. Knowing he cannot defeat Scylla, he chooses to sacrifice some of his men to save the ship and the rest of the crew. This demonstrates his cunning and ability to make tough decisions for the greater good.
Odysseus' crew lost six men when passing Scylla, one man for each head of Scylla.
Circe advised Odysseus to sail closer to Scylla and sacrifice a few sailors rather than risk losing his whole crew by getting too close to Charybdis and potentially sinking the entire ship. She warned him that it was better to lose a few men than risk the lives of everyone on board.
Scylla snatched 6 of Odysseus' best men as they passed, one for each of Scylla's six heads.
In Book 12 of "The Odyssey," Odysseus and his men are slowed down by the Sirens, Scylla, and Charybdis. The Sirens sing enchanting songs that lure sailors to their doom, while Scylla is a six-headed sea monster that devours passing ships. Charybdis, on the other hand, creates a whirlpool that threatens to swallow the entire ship. These obstacles force Odysseus to navigate carefully and strategically to ensure the survival of his crew.
To make sure that his crew stay calm and not think that he's crazy to go up against a giant snake and whirlpool

The crew is less willing to obey Odysseus now because they have grown tired of the long journey and faced numerous challenges and losses along the way. They have also become more skeptical of Odysseus' leadership abilities as he struggles to bring them back home. Additionally, the crew's morale may have been affected by their encounters with dangerous creatures and gods during their journey.
