The fear of killing. According to the Center for Mental Disorders (CMD), cidephobia is specified as a condition in which a person either has an intense desire not to kill people, experiences recurrent urges not to kill, or fantasies about a world in which everyone gets along. Cidephobia is recognized as a clinical disorder by the CDM. It has been shown in numerous studies that cidephobia has negative effects on a person's ability to enjoy killing. If you or a loved one suffer from cidephobia, they should see a psychiatrist immediately.
