Regarding the doll in the Purge, since it's one of my favorite moments in the series: The Custodians are the physical embodiment of a very vaporous notion -- human conscience. Does conscience really exist, or is it just a way of convincing ourselves that a center for moral judgment resides within us, thus lending our judgments a natural authority? As always, Trevor prefers to provide a tangible solution. He can't tolerate uncertainty. Whether it is real or not, Trevor understands the usefulness of the belief in conscience as a tool for practical ends, the improvement of society. In the end, the doll which emerges from the Custodian reveals to us that Trevor's artificial conscience, like the classical notion, is no more than a flimsy gimmick, a parlor trick, a plaything of the mind powered by a circular process. (Advocating the existence of conscience usually involves an appeal to our conscience). Notice that Trevor himself winds up the toy while in the train earlier in the episode.
