Why do Odysseus men get killed in sailing from troy?

Odysseus's men are killed during their journey home from Troy primarily due to their disobedience and poor decision-making. After winning the Trojan War, they encounter various obstacles, including the temptation of the Cicones, the enchantment of the Lotus-Eaters, and ultimately the wrath of Poseidon after Odysseus blinds the Cyclops Polyphemus. Their failure to heed warnings and their indulgence in reckless behavior lead to disastrous consequences, resulting in the loss of many lives.
