For the purpose of creating a peaceful society, the antagonist, Father, who is ruler of Libria in Kurt Wimmer's film "Equilibrium" (2002), eradicates the "true source of man's inhumanity to man" - one's ability to feel. In this way, he believes as humankind is one, war is gone and hate is a memory. However, without feeling, it has no point for humans to exist, and Libria becomes simply a seemingly placid society, where citizens are not content with their lives at all. Mary O'Brien, who is arrested for violating the law of Libria says, "To feel is as vital as breath. And without it, without love, without anger, without sorrow, breath is just a clock ticking" (Equilibrium 29:39). Having feeling, emotion, and expression is indispensable for human beings since the origin of mankind, but sometimes, having them ignites rage, wars, and conflicts. After all, it is basically the natural process they have to go through. "Equilibrium" is set in 2072 in Libria after the World War III. Father believes as long as people become emotionless, there will be no more war, thus enacting the law that people are required to take the daily injection of "Prozium", which temporarily takes away people's feelings. What's worse, Grammaton clerics are obliged to execute "sense offenders", people who refuse to take the injection. All emotionally stimulating items are also prohibited, such as art, literature and music. One of the rebel clerics Errol Partridge says, "Everything that makes us what we are traded away" (Equilibrium 16:55). As he is caught by another elite cleric John Preston reading a book "The Poetry of William Butler Yeats". Partridge states that life is meaningless without feelings and the exact meaning of humans' existence is merely of nothing. Somehow, Preston is not able to understand Partridge under the circumstances that he is emotionless, and therefore he kills him. Afterwards, Preston is assigned to destroy the underground society, where sense offenders gather. The turning point appears as Preston accidentally drops his Prozium and decides not to take it again. Actually, what makes his decision is because Father arranges that Preston's Prozium to be changed to a Placebo, which enables Preston to feel and seduces him to stop taking Prozium. In this way, Preston may seek to join the underground society and then Father is able to decimate all of the sense offenders. Instead, Preston plots with the Resistance to assassinate Father
