Dennis Theodore[1] Nedry was the main antagonist during the first half of the original Jurassic Park film. He was a computer programmer at Jurassic Park. Due to his financial problems and low salary, he accepted a bribe from Biosyn to smuggle dinosaur embryos off the island.
In both the film and the novel, he is slain by a Dilophosaurus. He was directly responsible for the events that happened in both the novel and film. A combination of factors led to his demise: despite working in a career around dinosaurs and other prehistoric creatures, he had a limited knowledge of them, and greed, which was intertwined by desperation to pay off his debt collectors and make himself rich after that.
Stories about “science gone awry” are almost always about non-scientists screwing up.
