We start by considering the role of intraspecific aggression within an overall adaptive strategy of survival and reproduction that may have an attendant effect of producing collateral harm to others, and then proceed to a theoretical analysis of risk-taking behavior as potentially producing harm to the self in certain environments. We conclude that social deviance is not as pathological as traditionally supposed and propose a strategic, rather than hydraulic, model of aggressive motivation. We consider the major characteristics of what has been called social deviance, particularly in relation to aggressive behavior that may occasion harm to other members of society, and how social deviance and aggression relate to critical individual differences in reproductive life history strategy.
