The study of crimes against human life is gaining space within the behavioral sciences and awakens the interest of government decision-makers, multilateral organizations and society. The different types and characteristics of these crimes are being investigated from biological, psychological, sociological and ecological approaches. The aim of this research is to determine the differentiating characteristics between the criminological profiles of the murderers. A qualitative, descriptive and applied methodology is used, through the review of literature and case studies. It is found that, beyond age, sex, and race, it is difficult to establish conclusive results in criminological studies. The main differentiating criterion of the serial killer is the emotional cooling time. Also, there is an outstanding similarity between mass murderers and terrorists; the main difference lies in ideological and political motivations.
