Polite Leader

The "Polite Leader" is the main antagonist of the sci-fi thriller known as the Purge - though the film is set in a dystopian future so it can be argued the bigger bad of the movie is the government itself, however the Polite Leader acts as the main antagonistic force in the film alongside his gang of "purgers".

The Polite Leader is a genocidal criminal who seeks to cleanse America of unwanted (such as homeless) and threatens to kill the protagonist's entire family unless they surrender a homeless man that stumbled onto their property, he shows a perverse sense of respect for those of high social class and does not wish to kill his "own kind" if possible but has no qualms with murder, rape and other atrocities towards the lower classes.

The antics of the Polite Leader and his gang are allowed due to the dystopian rule of the annual Purge - in which all crime is legal and no emergency services are called out, part of a Social Darwinist agenda by 2022 America to get rid of the "unwanted" members of society.
