An example of utilizing a functionalist or Durkheimian approach towards explaining the social phenomenon of modern terrorism is sometimes made by going back to Durkheims' original study of suicide in France and applying the different types of suicide types (Egoistic, Altruistic, Anomic) to similar forms of suicidal terrorism types. A more contemporary example of this theoretical application of Durheimian thinking is visible in a book chapter written by Sociologist Mahmoud Sadri who applies these suicide types to suicidal homicides whether they are egoistic, altruistic, or anomic and their visible frequency in both western and non-western cultural domains. According to the Chapter written by Mahmoud Sadri, in western and non-western cultures, egoistic suicidal homicides often resemble suicide pacts or simple murder suicides, whereas altruistic suicidal homicides which are found in western and non-western cultures might consist of suicide missions, ideological suicide missions, or acts of Terrorism (Ex: Kamikaze attacks). Finally, anomic suicidal homicides also frequently produce acts of terrorism in both western and non-westerns cultures and likely involve mass suicide pacts or mass murder suicides (EX: In Western cultures, for example, Columbine Murders , Heaven's Gate, Jonestown or Branch Davidian mass suicides, while in non western cultures, for example, ISI of Pakistan;PKK or activities endorsed by the PMO).
