Love and hatred are often seen as opposites. From a standpoint of emotion classification, love can be defined as a mixture of joy and acceptance, and the joyful acceptance of and by another. The opposites of joy and acceptance are sadness and disgust, respectively. From this, it has been inferred (in the previous chapter) that the opposite of love is not hatred but rather loneliness-forlornness. Hatred and loneliness share the primary emotion disgust, as the object of hatred is rejected and even seen as morally disgusting. But hatred does not involve sadness; hatred rather involves a dynamic of anger and fear. More specifically, three primary or basic emotions—anger, fear, and disgust—are the hypothesized elements of hatred. These three emotions combine in pairs to form three secondary emotions: frozenness/tonic-immobility (anger and fear), revulsion (fear and disgust), and contempt (anger and disgust). This chapter identifies an absence of love as a causative factor in the mentality and behavior of hate-infused violent criminals, their hatred of life, and their hellish experience of life as the living death. A comparison is made of the present hierarchical-classification theory’s model of hatred and Sternberg’s triangulation theory of hate.
