How Does this Link to the Cornelian Principles?

Compassion: Hope itself shows an act of compassion, either by the gods allowing it to remain or Hope itself choosing to remain.  By remaining in the jar Hope gives humans the emotional support to endure life's difficulties despite the overwhelming hardship.

Courage: Despite the evil spirits surrounding her, Pandora still has the courage to close and reseal the jar. One could argue that she also shows courage in opening the jar despite not knowing what it will release. 

Generosity: The gods show generosity by giving Pandora so many gifts and attributes. 

Gratitude: Epimetheus expresses his gratitude for being gifted Pandora by the gods by readily accepting her.

Integrity: Pandora demonstrates her moral integrity when she realises the mistake she has made in opening the jar and then closes it in time to preserve hope. 

Joy: Both Pandora and Epimetheus experience great joy in the world and their marriage.  

Respect: Pandora and Epimetheus both respect the gods and revere them.
