Doctor: I can't. Only... it's always easy to see a great mastermind at work behind thing. And they do exist - believe me, I've met quite a few. But the thing is, people are such frail, weak beings. It doesn't need a man twirling a black cape. Some of the worst decisions in history have been made in rooks by people who meant well. There's a reason they say nothing good ever comes out of a commitee. Beware of Focus Groups, Working Parties, Conference Calls, and people who find ninety-nine reasona to say no before they find a single reason to sat yes. It's these people who are responsible for most of the evil in the universe. And it's why they're all unaccountable. None of them can even remember making the big, awful decision. No one person decided to build a Death Ray. Perhaps someone can remember making some useful tweaks to the firing nozzle, a few good suggestions at an away day about the Death Ray logo, or perhaps deciding that the nice big button should be red...but...oh, I'm always asked what the end of the universe will be like. It'll be a room full of people fighting politely over the last chocolate biscuit as they squeeze in one final meeting about how terribly dark it's getting.
