ON Jurassic World...

The problem with making Dinosaurs for military operations isn't that it's inherently wrong--IIRC, that's kind of the purpose of the raptor pack: To see if raptors could have been trained to work with humans.

The problem is 1: The Indominus was made for military operations... At the insistence of one ACU commander(the guy who got eaten by a raptor and, IIRC, had no idea what he was talking about when referring to the raptors earlier) and Wu... Without the knowledge or permission of the CEO of either the Park or the Parent companies. They were basically going behind everyone's back to do it.

2: The Raptor training program wasn't completed yet... and yet they still made a bigger, smarter, more agressive, and more sadistic raptor that could turn invisible. Then they confined it and it's sibling alone in a pen that was far too small for one such animal, let alone two, which resulted in a large, inherently predatory and sadistic creature of near human, if not human*, intelligent becoming a complete and utter sociopath.

The problem isn't that they made a weaponized dino. The problem is that they took "make something scary" as blanket permission to screw everyone over and make a complete and utter monster for the personal profit of two people and mucked it up every step of the way.

(Trivia, apparently Wu had been working on weaponized hybrids for longer than just the dominus without getting caught--On the Jurassic World website, there's a hidden page that indicates that there's an agressive prototype-hybrid on the island from 3, with that implicitly being an explanation for the inaccurate even by serious standards Spinosaurus.)

A smart person who wanted to make weaponized dinosaurs for profit would have waited until the research on training raptors was back, and then hybridized the raptors with something more docile and easily trained.

*There's a distinctly primate looking nervous system depicted in a lab scene that revealed some of the Indominus' parent species,and while not explicitly stated in film earliar drafts of the film did have the Indominus and it's counterparts in earliar still drafts as explicitly part human.
