Maybe there's justice in the world after all.
Muldoon states this in the chapter, "Search," late in the novel when he and Gennaro find Nedry's dinosaur-mauled carcass. Nedry, by recklessly stealing fragile and potentially very dangerous bioengineered material, is the novel's most irresponsible character. As the novel careens to a close, many of its main characters meet death at the hand of the dinosaurs, and it is important to note that these deaths do not necessarily happen indiscriminately. For the most part, each character meets a fate that is largely deserved in light of their earlier deeds and attitudes. Though Nedry's death is the most obviously appropriate fatality, we must bear in mind that Hammond is the one responsible for the entire park in the first place, and there is no reason to believe his fate will not catch up with him as well. Likewise, the cowardly Ed Regis, the irresponsible scientist Dr. Wu, and the cocky John Arnold meet similar ends.
Although the implications of Malcolm's chaos theory are dark—that there is no way of predicting the future and that disaster is imminent for those who rely too heavily on computers and calculation—Crichton undercuts this concept by giving each of his characters there just deserts. By the end of the novel we have the impression that, despite the seeming chaos and randomness of the world, there may nonetheless be some underlying order to it.
