What is the director wanting to tell us about W.C.K.D and all governments that wish to do the same thing?

Authoritarianism permeates The Death Cure: not only do we have WICKED operating trials and hunting Thomas, but we also have the anarchic regime of the Right Arm as a counterpoint to WICKED. No matter which way Thomas and his friends turn, they are confronted by powerful organizations that bend the will of their members to their overall objectives. It is no wonder, then, that the reader oftentimes questions whether it is even possible for people like Thomas to make decisions and act as free individuals. Human history is riddled with authoritarian regimes. The author warns how easily the world can fall into them again.
