Three reasons:
 * 1. Animals lack a morality. They can neither be good nor evil. We even have a rule in the Manual of Style stating not to use the villains category on animal articles or characters that are animals.
 * 2. You added character related categories to Mosasaurus and Indominus rex. These articles are meant to cover the whole species, not just a single individual. There could very well be another movie that features an Indominus that is male and is a hero like Blue making categories such as "Female characters" and "Villians" invalid.
 * 3. Using your logic, Charlie would be considered a villain rather than heroine because unlike her sisters who resided with Owen Charlie dies sided with Indominus which is the film's dinosaur villain and does not redeem herself.
