5. John Hammond - Jurassic Park
The moment a man declares not only do I want to bring dinosaurs back from the dead, but I want to build a theme park around them, you know hes taken megalomania to giddy new heights. His level of power-madness is rarely seen outside of a Bond villain, but even Max Zorin would baulk at the prospect of reversing extinction. And then monetizing it. The most worrying thing is its all for the sake of a tourist attraction, rather than for, say, a scientific world that could very likely benefit from the use of advanced cloning technology. For another madman of a similar calibre, see
The Truman Shows Christof, who kidnaps a small boy so he and the rest of the world can watch his whole life develop thanks to a hidden, 1984-style camera set-up.
