Why did Hercules perform the 12 feats?

Hercules was a demigod in Greek mythology, the son of Zeus and the mortal Alcmene. He is renowned for his strength and courage, and is best known for performing twelve superhuman feats, known as the Labors of Hercules.

The twelve labors were a series of tasks assigned to Hercules by King Eurystheus, who had been appointed by the gods to oversee Hercules' accomplishments. The labors were intended to demonstrate Hercules' strength and courage, as well as to atone for his past sins.

The first labor was to slay the Nemean Lion, a monstrous beast that was terrorizing the people of Nemea. The second labor was to slay the nine-headed Hydra, a serpent-like creature with nine heads. The third labor was to capture the Ceryneian Hind, a sacred deer that was sacred to the goddess Artemis. The fourth labor was to capture the Erymanthian Boar, a wild boar that was terrorizing the people of Arcadia. The fifth labor was to clean the Augean Stables, which were filled with years of accumulated filth. The sixth labor was to slay the Stymphalian Birds, a flock of man-eating birds that were terrorizing the people of Arcadia. The seventh labor was to capture the Cretan Bull, a monstrous bull that was terrorizing the people of Crete. The eighth labor was to steal the Mares of Diomedes, a herd of man-eating horses that were sacred to the god Diomedes. The ninth labor was to steal the girdle of Hippolyta, the queen of the Amazons. The tenth labor was to steal the cattle of Geryon, a monstrous three-headed creature who was terrorizing the people of Erytheia. The eleventh labor was to steal the apples of the Hesperides, a sacred grove guarded by a dragon. The twelfth and final labor was to capture Cerberus, the three-headed guard dog of the Underworld.

The twelve labors of Hercules were intended to demonstrate his strength and courage, and to atone for his past sins. By completing the labors, Hercules was able to prove himself as a hero and was accepted by the gods and goddesses of Mount Olympus.
