It was almost uncanny seeing the usually upbeat Wind God so furious. His whitened eyes peirced into your soul. No. No way in Olympus he was going to aid Odysseus.
You needed a wind bag to trap Poseidon's deadly storm inside. Poseidon sent that storm to kill Odysseus. He'd been after him for ten years now, waiting for the perfect time to strike.
Now that Odysseus was finally getting released off of Calypso's island, he was back at the endless waters, lying completely vulnerable to the tides. Aeolus was the only one who could help.
The more you kept pleading, the more annoyed he became. "No." Aeolus replied coldly. "I said to keep the bag closed, but he was incompliant. So, tell me, why should I help him get back to his island?"
The God was still pissed at the first time the bag was opened a decade ago. He knew that Odysseus wasn't the one who opened it, and it was Eurylochus. However, he could care less. His instructions were clear. The King of Ithaca failed to succeed.
Aeolus was also very aware that he spent nine days without sleep trying to keep the bag closed, away from his crew in which were trying to open it, thinking there was treasure. But again, he couldn't be bothered. In his mind, whatever it took to keep the sacred item closed, so be it. Even if it meant self torture.
