Why does he feel ashamed that poseidon saved him?

He feels ashamed that Poseidon saved him because he believes he should have been able to fend for himself without divine intervention. This reliance on a god undermines his sense of personal strength and autonomy, making him feel weak and unworthy. Additionally, he may struggle with the idea that accepting help from a powerful deity diminishes his own accomplishments and resilience. This internal conflict leads to feelings of inadequacy and shame.
