Myth is ripe for interpretation and I hope you often find yourself putting the book down and speculating on what the Greeks meant (or thought they meant) by Chrysaor and Pegasus bursting from the severed neck of Medusa, or how they distinguished between the Harpies, the birds from the Isle of Ares, and the Stymphalian birds. Myths are not crossword puzzles or allegories with single meanings and answers. Fate, necessity, cause, and blame are endlessly mixed in these stories as they are in our lives. They were no more soluble to the Greeks than they are to us.
