this is a classic retelling of the hero myth - like Campbell's "Hero With a Thousand Faces."
are you familiar with it? sounds like you are - or else instinctively came to the same kind of conclusion without realizing it!
How long, LORD, must I call for help, but you do not listen?
Or cry out to you, “Violence!” but you do not save?
Why do you make me look at injustice?
Why do you tolerate wrongdoing?...
Therefore the law is paralyzed, and justice never prevails....
