Why was Heracles ordered to perform 12 labors?

Heracles was ordered to perform the 12 labors as a punishment for killing his wife and children in a fit of madness, which had been inflicted upon him by the goddess Hera. To atone for his actions and regain his honor, the Oracle of Delphi advised him to serve King Eurystheus, who devised these seemingly impossible tasks. Completing the labors would not only redeem Heracles but also prove his strength and heroism. Ultimately, the labors became a testament to his resilience and ability to overcome great challenges.
