Too, too many to list, but here's some of the darker one's:
From Black Hawk Down...that moment in life when all hell is breaking loose and someone looks for sympathy when there's no time for sympathy, only action. 8 of 10 people will likely know a situation when this was applicable:
Colonel: Get into that truck and drive.
Sergeant: But I'm shot, Colonel.
Colonel: Everybody's shot, get in and drive.

From 'The Dark Knight".... about the extremely small percentage of people who do things that are simply beyond our comprehension:
Bruce Wayne: Targeting me won't get their money back. I knew the mob wouldn't go down without a fight, but this is different.
They crossed the line.
Alfred Pennyworth: You crossed the line first, sir. You squeezed them, you hammered them to the point of desperation.
And in their desperation, they turned to a man they didn't fully understand.
Bruce Wayne: Criminals aren't complicated, Alfred. Just have to figure out what he's after.
Alfred Pennyworth: With respect Master Wayne, perhaps this is a man that *you* don't fully understand, either.
A long time ago, I was in Burma. My friends and I were working for the local government.
They were trying to buy the loyalty of tribal leaders by bribing them with precious stones.
But their caravans were being raided in a forest north of Rangoon by a bandit.
So, we went looking for the stones. But in six months, we never met anybody who traded with him.
One day, I saw a child playing with a ruby the size of a tangerine. The bandit had been throwing them away.
Bruce Wayne: So why steal them?
Alfred Pennyworth: Well, because he thought it was good sport. Because some men aren't looking for anything logical, like money.
They can't be bought, bullied, reasoned, or negotiated with. Some men just want to watch the world burn.

And the last of the dark quotes:
"Not everybody is the perfect person in the world," Pryor said of Vick. "Everyone does -- kills people, murders people, steals from you, steals from me. I just feel that people need to give him a chance."
September 6, 2009 after win over Navy, Terrell Pryor who had the word VICK on the eye black sticker under his left eye, showing his support for Michael Vick.
