This study aims to examine the psychopathological profile of non-homicidal sexual offenders (NHSOs) and homicidal sexual offenders (HSOs). Using an incarcerated sample of 96 NHSOs and 74 HSOs in a federal penitentiary in Canada, these offenders are compared in terms of their offending process, maladaptive personality traits, and paraphilic behaviors. A number of cross-tabular and sequential logistic regression analyses are performed. Relative to their counterpart, findings indicate that a higher percentage of HSOs select a victim of choice, report deviant sexual fantasies, mutilate their victim, and admit to their offense upon apprehension, whereas a higher percentage of NHSOs select victims with distinctive characteristics. In addition, a higher percentage of HSOs manifest paranoid, schizotypal, borderline, histrionic, narcissistic, obsessive-compulsive, and impulsive personality traits, and overall odd and eccentric personality traits compared with NHSOs. Similarly, a higher percentage of HSOs engage in exhibitionism, fetishism, frotteurism, homosexual pedophilia, sexual masochism, and partialism compared with NHSO. These findings are discussed with their implications for offender profiling.
