Why do stormy think the sea has betrayed him?

In Shakespeare's play "The Tempest," Caliban feels that the sea has betrayed him because it was once a source of life and connection, but now it has become a symbol of his isolation and suffering. He perceives the sea as a barrier that separates him from his freedom and rightful place on the island, which he believes should be his. This sense of betrayal deepens his resentment towards Prospero, who he feels has usurped his home and subjected him to servitude. Ultimately, Caliban's feelings reflect a profound disconnection from both nature and his own identity.
