Terrorists are sometimes considered psychopathic, and comparisons may be drawn with traits such as antisocial violence, a selfish world view that precludes the welfare of others, a lack of remorse or guilt, and blame externalization.[citation needed] However, John Horgan, author of The Psychology of Terrorism, argues that such comparisons could also then be drawn more widely: for example, to soldiers in wars. Coordinated terrorist activity requires organization, loyalty and ideological fanaticism often to the extreme of sacrificing oneself for an ideological cause. Traits such as a self-centered disposition, unreliability, poor behavioral controls, and unusual behaviors may disadvantage or preclude psychopathic individuals in conducting organized terrorism.[57][58]
