Ethical dualism (from ancient Greek ἔθος (o ἦθος), ethos,"character", "custom", and Latin duo, "two") refers to the practice of imputing evil entirely and exclusively to a specific group of people, while disregarding or denying one's own capacity to commit evil. The consequence of such stance is the creation of an "Us" versus "Them", thereby polarizing social configurations into extremes in a way that mutual understanding between the two "poles" is made very difficult or impossible, since the "Them", the "Other", is demonized, dehumanized.
