Suicide to Harass Others

Suicide among Animals: A Review of Evidence

Naturalists have not identified suicide in nonhuman species in field situations, despite intensive study of thousands of animal species. In this review, evidence on suicidal behavior among animals is analyzed to discover analogies with human suicidal behavior. Literature was retrieved by exploring Medline/PubMed and PsychINFO databases (1967–2007) and through manual literature searches. Keyword terms were “suicide or suicidal behavior” and “animal or animal behavior.” Few empirical investigations have been carried out on this topic. Nevertheless, sparse evidence supports some resemblance between the self-endangering behavior observed in the animal kingdom, particularly in animals held in captivity or put under pressure by environmental challenges, and suicidal behavior among humans. Animal models have contributed to the study of both normal and pathological human behaviors: discovering some correlates of suicide among animals could be a valid contribution to the field.

Animal model and neurobiology of suicide

Animal models are formidable tools to investigate the etiology, the course and the potential treatment of an illness. No convincing animal model of suicide has been produced to date, and despite the intensive study of thousands of animal species naturalists have not identified suicide in nonhuman species in field situations. When modeling suicidal behavior in the animal, the greatest challenge is reproducing the role of will and intention in suicide mechanics. To overcome this limitation, current investigations on animals focus on every single step leading to suicide in humans. The most promising endophenotypes worth investigating in animals are the cortisol social-stress response and the aggression/impulsivity trait, involving the serotonergic system. Astroglia, neurotrophic factors and neurotrophins are implied in suicide, too. The prevention of suicide rests on the identification and treatment of every element increasing the risk.

Rethinking Suicide Bombing

Background: Current issues in the emerging psychiatric literature on suicide bombing tend to center around the pathologies of suicide bombers and the role of psychiatry as an adequate tool for analysis. Aims: Attention to broader social science research may allow mental health professionals to develop more accurate models of behavior to explain and possibly prevent future attacks. Methods: The psychiatric literature on suicide bombing was reviewed and compared to similar anthropological literature. Results: A probe into the methodologies of researching suicide bombing, definitions of “war” and “terrorism”, and beliefs on life, death, homicide, and suicide demonstrate that most of the psychiatric literature reflects a particular perspective which aspires towards a certain universalism. Conclusions: Anthropological approaches can disclose standpoints taken for granted since any interventions with respect to suicide bombing must eventually account for values which are ultimately culturally determined.

Attitudes toward suicide bombing in Pakistan

Although suicide bombing is a historical phenomenon, there has been a recent upsurge in such incidents. In Pakistan, over the last year, more than 1,000 people have been killed in suicide bombing incidents. Assessing the attitudes and perceptions of people toward suicide bombing can help understand some of the root causes of this phenomenon. In this pilot study, we conducted a cross-sectional survey of people (N = 215) in Karachi, Pakistan, to assess their attitudes and perceptions toward suicide bombing. The majority of the respondents condemned suicide bombing and disagreed with the notion that Islam or any other religion supports it. Belonging to the Sunni Muslim sect and strong adherence to religion predicted support for suicide bombing. The majority believed suicide bombing to be a result of religious fundamentalism. Opinion was divided as to whether suicide bombers have an underlying psychiatric illness. Further studies with larger sample sizes are needed to determine the attitudes and perceptions of the Pakistani population regarding this important issue.
