“…Thus, substance misuse had a major mediating role between psychosis and violence but it exerted a lesser influence between psychosis and homicide (Fazel, Gulati, et al, 2009). Bennett et al (2011) found higher rates of substance misuse in homicide offenders with or without schizophrenia, than in the general population. They concluded that comorbid substance misuse could not explain the association between homicidal violence and schizophrenia.…”

The aim of this article was to compare the characteristics and outcome of homicide and non-homicide mentally disordered patients all of whom had been hospitalised. Seventy-four patients with a homicide conviction were compared with 521 convicted of a non-homicide offense. The former group were older, were more likely to be diagnosed with schizophrenia but less likely to have suffered from childhood adversity, and had less criminality. They also had fewer convictions during the follow-up. Little distinguished these two groups with both suffering from multiple disadvantages suggesting the need for ongoing care and support.

“…However, as these are cumulative results from up to 32 years of follow-up, with varying duration of followup for each proband, comparison to incidence rates of murder or rape in the general population could not be calculated. Nevertheless, relatively high rates of murder committed by patients with schizophrenia have been described by other authors (Eronen et al 1996;Wallace et al 1998;Fazel et al 2009b;Bennett et al 2011).…”

“…A number of studies have concluded that a greater proportion of individuals with schizophrenia are involved in violent or aggressive behaviour than individuals from the general population, particularly during untreated first episode psychosis (Bennett et al, 2011;Fazel, Gulati, Linsell, Geddes, & Grann, 2009;Large, Smith, & Nielssen, 2009;Nielssen & Large, 2010).…”

“…This is because factors that predict violence in the general community including social disruption, history of abuse, low income and drug and alcohol abuse also predict violence in schizophrenia (Bennett et al, 2011;Bo, Abu-Akel, Kongerslev, Haahr, & Simonsen, 2011;Elbogen & Johnson, 2009;Fazel et al, 2009;Wallace et al, 1998). In particular, impairments in empathy associated with substance abuse may increase propensity to violence (Bragado-Jimenez & Taylor, 2012).…”

Introduction. Disordered moral behaviour and understanding of moral rules were described early in the literature on schizophrenia; however, moral cognition has received scant attention in spite of a large literature focused on social cognitive impairments and violent behaviour in schizophrenia. Methods. We conducted a narrative synthesis of the literature on violence, moral judgement and schizophrenia. Results. Initial empirical research into moral cognition in schizophrenia did not fully account for the basic-and social-cognitive deficits now known to characterise schizophrenia. Importantly, research into moral cognition in autism and psychopathy, disorders in part characterised by social cognitive impairments indicates subtle patterns of difference to the moral cognition of control participants. Recent neuroeconomic studies of moral cognition in schizophrenia have indicated that individuals with schizophrenia display subtle dysfunction in their fairness-related behaviours, but not in their propensity to engage in altruistic punishment. Conclusions. Further research has the potential to broaden our understanding of what is intact and what is impaired in moral cognition in schizophrenia and also to inform our theories of the structures subserving moral judgement in the general population. Furthermore, a more thorough understanding of moral cognitive impairments in schizophrenia may have implications for both legal process and psychosocial rehabilitation.

Schizophrenia disorders, substance abuse and prior offending in a sequential series of 435 homicides

Abstract: The association between homicidal violence and having a schizophrenia disorder cannot be explained away simply on the basis of either comorbid substance abuse or prior criminal offending.
