In "Perseus and Medusa," the behaviors of the gods can often be interpreted as reflecting their roles as both guardians and manipulators of fate. The gods in Greek mythology frequently intervene in the lives of mortals, helping or hindering them based on their own whims, rivalries, or allegiances.
One inference that is strongly supported by the story is that the gods play a significant role in shaping mortal destinies. For example, in the case of Perseus, he receives assistance from Athena and Hermes, who provide him with the tools he needs to defeat Medusa. This suggests that the gods are willing to aid certain mortals in their quests, but also that their assistance can be key to overcoming formidable challenges.
Additionally, the gods’ behaviors often reflect their personalities — Athena's wisdom and protection contrast with the more capricious or vengeful actions of other gods in different stories. Overall, the inference that the gods actively influence the fate of mortals and often take sides in their endeavors is a central theme that emerges from the narrative of "Perseus and Medusa."
