How did the values expressed by Achilles in this quote along with the development of a basic system of democracy help the Athenians to dominate the Mediterranean? How would their democracy and their values eventually lead to the collapse of their empire? Heres the quote

“My mother Thetis, a
moving silver grace,
Tells me two fates sweep
me on to my death.
If I stay and fight, I’ll
never return home,
But my glory will be
undying forever.
If I return home to my dear
fatherland
My glory is lost but my life
Will be long,
And death that ends all will
not catch me soon.”

Thanks!!
