Indominus Rex is a highly intellegent creature. It remembered where the tracking device in it was and ripped it out. It is killing other dinosaurs and controlling them, and allowing them to kill humans.

It just seems to be using it's intellegence to not be controlled by the humans, being "indominus," or not being able to be dominated. As such, it wants to free the dinosaurs and/or let them take the natural course of nature (which was Indominus hunting the dinosaurs). However, Rexy may want her position back as the top of the chain, and I believe will battle Indominus in a final duel. (And I'd love it if Rexy won. Rexy is freak'n awesome.)
