Grey's Anatomy, Season 6

Owen:
[voiceover] Living is better than dying... until it's not. But even if letting a person die is the right thing to do, it's not what surgeons are built for. We are arrogant and competitive. We don't like to lose and death feels like a loss even when we know it's not. We know it's time. We know it's right. We know we did everything we could. But it's hard to shake the feeling that you could've done more.
