In Greek mythology, what was Zeus seeking revenge for when he created Pandora?

Zeus created Pandora as part of his punishment for Prometheus stealing fire and giving it to humanity.

Prometheus is a Titan associated with forethought and humanity. In the myth, he helps humans and obtains fire for them, defying Zeus’s wishes. Zeus responds by arranging a different kind of punishment: he orders the creation of Pandora, a woman presented to Prometheus’s brother Epimetheus.

Pandora’s arrival is connected with the release of suffering among humans. Hesiod’s Theogony and Works and Days give related but not identical accounts of the conflict between Zeus and Prometheus. Works and Days develops the story of Pandora and the container most fully.

The myth is not simply a story about curiosity. It is also an etiological explanation, meaning a story that explains why a condition exists. In this case, Pandora’s arrival and the opened container help explain why human life includes hardship, illness, labor, and other troubles.
