what does the goddess Hera suggest about the worth of femininity?
about psychological development? about maturity? about relationships?
what positive and negative values does Hera represent for modern human
beings?

That although it is worth a lot it is often repressed and discarded.

That certain emotions when unchecked can form a strong character and
eventually dictate the persons actions.

That maturity is realized not through age or experience but rather
through the coming through experiences in a fashion that benefits
society.

That love and hate are the two closest emotions and when trust is
broken once it is harder to repair than any other part of your
character.

Positive: Dedication, Power, Love.  Negative: Hate, Spite, Revenge, Cruelty
