Why did Aeolus think Odysseus was cursed by the gods?

Aeolus believed Odysseus was cursed by the gods because, despite providing him with favorable winds to sail home, Odysseus's journey was thwarted by misfortune. When his crew opened the bag of winds, they were blown off course, leading to further troubles. This series of unfortunate events suggested to Aeolus that Odysseus was fated to suffer divine wrath, prompting him to refuse further assistance.
