Actually the Leviathans are not only intelligent, but they're the most calculating villians ever shown on the series. They have no intention of destroying the natural order of creation because if they do, Death would get involved and they don't want that to happen. Humans are an easy snack. That's why they've painstakingly devised a master plan to breed and raise us into the perfect cattle instead of wiping us out without inhibitions. The world is their controlled barnyard. And we are their processed meat tainted with high fructose corn syrup to their tastes.

Let's hope in season 8, they put a complete end to the Leviathans. And start with the origin and introduction of Metatron and other cosmics - maybe like aspects of God.
