Comics are the last morality plays
In the real world there seems to be precious few "heroes" left anymore.
If you think about comics or even our popular novels, heroes come in many layers.
When we are children,
we believe heroes fight injustice
because it is the right thing to do.
As we mature, we realize that what prompts someone to fight the good fight
can differ greatly from one person to the next.
Some fight AGAINST something or someone, say like Batman.
Others fight FOR something or someones, like Captain America.
Then, there is the complex reasoning behind Wonder Woman
who steps outside the box of our heroic expectations:
Why does your protagonist
fight the "good fight"
and what makes it good
in your eyes?
