"I spared her life."
"You let one of them go ... but that’s nothing new. Every now and then a little victim is spared. Because she smiled. Because he’s got freckles. Because they begged. And that’s how you live with yourself. That’s how you slaughter millions. Because once in a while, on a whim, if the wind’s in the right direction ... you happen to be kind."
Conversation between Margaret Blaine (Blon Fel-Fotch Pasameer-Day Slitheen) and the Doctor in the Doctor Who episode 'Boomtown'.
