I'd be the guy with all the answers. I'd have spies everywhere telling me what's going on in all areas of the world and not a single person working for me would know I'm the big guy on top. I'd have the type of organisation where everyone is sure they are evil, but no-one could prove it. With a single secret, governments could be toppled, wars started or ended, and heroes become the villains.
Then one day I'd just get bored, upload the whole load of secrets onto Twitter and get in the biggest most comfortable bunker and wait for all of it to blow over.
