Criminaloids refers to a term used by Cesare Lombroso to describe occasional criminals who were pulled into criminality primarily by environmental influences.
They are individuals who have engaged in criminal behavior, but who may not have a long-term pattern of criminal activity. These individuals may have been influenced by factors in their environment, such as a lack of economic opportunity, exposure to criminal peers, or other negative social influences. They may have been drawn into criminal behavior as a result of these environmental factors, but may not necessarily have a strong inclination towards criminal activity. Occasional criminals may be more likely to be motivated by immediate needs or incentives, rather than a long-term commitment to criminal activity.
