The Dark Knight2008

[Two-Face holds Gordon's son at gunpoint, and Batman arrives to save him]

Batman:
You don't want to hurt the boy, Harvey.

Two-Face:
It's not about what I want, it's about what's fair! You thought we could be decent men in an indecent time. But you you were wrong. The world is cruel, and the only morality in a cruel world is chance. Unbiased, unprejudiced, fair. His son has the same chance she had. [Shows both sides of his coin] Fifty-fifty.

Batman:
What happened to Rachel wasn't chance. We decided to act. We three.

Two-Face:
Then why was it me who was only one who lost everything?

Batman:
[quietly] It wasn't.

Two-Face:
The Joker chose me!

Batman:
Because you were the best of us! He wanted to prove that even someone as good as you could fall.

Two-Face:
[bitterly] And he was right.
