10. John Hammond - Jurassic Park

Talk about a guy who just doesn't get it. What about bringing back a species of reptiles that are hundreds of times the size of humans and a milion times stronger than any living thing sounds like a good idea? Dinosaurs are huge and sometimes scary, but Hammond brings the likes of T-Rex and Velociraptor back into existence with a big moronic grin. Not only that, but how does he plan to save the world from his horrible theme park? A couple of shot guns and a flimsy electric fence even your neighbor's dog could get through with enough determination. Speaking of electric fences, talk about the worst security system ever created. What happens if the power goes out, John?
