What is the bet of Perseus if the monster is killed?

If Perseus successfully kills the monster, typically referred to as the Gorgon Medusa in his myth, he stands to gain glory, fame, and the gratitude of those he saves. Additionally, he would likely secure the hand of Princess Andromeda, whom he rescues from a sea monster, thereby solidifying his status as a hero. The victory would also affirm his lineage and the favor of the gods, particularly Athena and Hermes, who aid him in his quest.
