What did Zeus do to retaliate against humans?

In Greek mythology, Zeus retaliated against humans primarily through the Great Flood, which he unleashed to punish them for their wickedness and impiety. He decided to wipe out humanity after observing their moral decline and disobedience to the gods. Only a few, like Deucalion and Pyrrha, were spared, as they were deemed virtuous and went on to repopulate the earth. This act demonstrated Zeus's authority and the consequences of defying divine order.
