User blog comment:Dinosaurus1/Why Maisie freed the dinosaurs (and why it is not as bad as you might think)./@comment-4864110-20190120220408

The way I see it. Mills would have gotten away with the bone sample of the Indominus rex if Maisie hadn't released them. Also, if she hadn't done that, Mills would use that bone sample to create more dangerous hybrid carnivores and perhaps do so on all the dinosaurs. Imagine if the I-rex DNA put in the Triceratops, Stegosaurus, Allosaurus, Carnotaurus, Pteranodon, Stygimoloch, Ankylosaurus and maybe even Compsognathus, which would become too dangerous for hybrids on be on this planet than the current dinosaurs in California. Because of Maisie letting them out, the T-Rex devoured Mills and destroyed that bone sample of the Indominus rex. So therefore, she probably saved the world from such catastrophe.
