You said she won the cosmic lottery. Lotteries are random. That means she was randomly chosen. That’s what that word means. And whether she was “chosen” or not is completely debatable.
Touché, but considering how virtuous, and perfect she is, I take back the cosmic lotery statement, and maintain she was chosen to be the hero:
“Darkness rises, and light to meet it.”
She is thus her destiny to be the defender of the light, not by choice.
That’s still your interpretation. It was someone’s destiny to defend the light. She made the choice to be that someone.
