Dennis Nedry, Jurassic ParkRead about another entry on the list.
Granted, Nedry didn’t have a world-ending catastrophe in mind when he betrayed his employer, stealing a bunch of dinosaur embryos and shutting down Jurassic Park’s security systems in order to make his escape. He just wanted to make a quick, cool million bucks. But for sheer scale of consequences, Dennis Nedry is one helluva turncoat; even Benedict Arnold fell short of unleashing a horde of hungry velociraptors on an unsuspecting public in the process of changing sides.
Jurassic Park is among Chuck Wendig's five books that prove mankind shouldn’t play with technology, Jeff Somers's top seven books that explore what might happen when technology betrays us, Damian Dibben's top ten time travel books, and Becky Ferreira's eleven best books about dinosaurs.
