If we are honest, we all have an agenda. My own agenda is shaped by a passage my mom taught me, Micah 6:8. It teaches that what God requires is that we seek justice, love mercy, and "walk humbly with our God."
The question of whether we see the world through the eyes of Javert or Valjean amounts to our understanding of justice. For Javert, justice is retribution in the interest of maintaining an abstract order; for Valjean, justice is solidarity in the interest of personal love.
