The scary bit is when you realize that Bond villains were invented by Ian Fleming—former journalist, secretary to the Chief of Naval Intelligence during WW2, and UPPER CLASS NOB WHO KNEW THESE PEOPLE IRL. (By "these people" I mean rich entitled bastards with hench-thugs.)
I'm pretty sure his creative process was, "what would that dirty rotten scoundrel from my year at Eton do if he was put in charge of a crime syndicate? And was in a position to get his hands on a couple of H-bombs? Ah, yes." (Type-tappity-type.)
