The Dark Knight (2008)
In the final encounter, Harvey Dent summarized the morality of the cruel world to Commissioner Gordon.
You thought we could be decent men in an indecent time. But you were wrong. The world is cruel, and the only morality in a cruel world is chance.

Unbiased. Unprejudiced. Fair.
– Harvey Dent (Two-Face)
