Moral fiber is the capacity to do what is right, no matter what the circumstance. A business person with strong moral fiber, for example, would decline a bribe, and put his self interests aside for the benefit of the company and its shareholders. A parent with strong moral fiber does whatever it takes to help their kids succeed, even if it means they have to make sacrifices. A person with moral fiber does not do things to intentionally harm others, and when given the opportunity, does things to help the less fortunate.
When Abraham Lincoln pushed to free slaves despite hostility from his own political party, he showed great moral fiber.

Bernie Madoff was severely lacking moral fiber when he took billions from investors.

A parent that would rather drink and get high than pay rent or electric bills has no moral fiber.

"Moral fiber's about finding that one thing you really care about. That one special thing that means more to you than anything else in the world. And when you find it, you fight for it. You risk it all, you put it in front of everything, your life, all of it. And maybe the stuff you do to help her isn't so clean. You know what? It doesn't matter. Because in your heart you know, that the juice is worth the squeeze. That's what moral fiber's all about."

- Movie: The Girl Next Door
"You know, he's got great moral fiber. Regardless of circumstance, he stands by his convictions."

The one thing you find that makes you completely happy... the one thing you cant live without. Once you find your moral fiber, you continue to chase after and do whatever it takes to help your moral fiber.

You are my moral fiber.
