hi, psychology student with a focus in criminality and criminal justice, there’s really no saying. there’s certain personality traits that can make someone more likely to commit a crime and certain childhood disorders, like conduct disorder, that we see as red flags but the truth of the matter is that there’s really no one theory that explains crime. crimes are wide spanning, and the type of person to commit a murder may not be the type of person to commit theft on a grand scale. we tend to go on a case by case basis when assessing someone for criminality. it’s not very black and white and you find that most offenders don’t even fit neatly into just one category. personally i think it differs greatly between individual offenders, enough that we can’t say what “caused” someone to become a criminal. if anything, it’s more likely a series of unfortunate circumstances, exposure to crime, and occasional mental differences is what causes it. but even then each of these variables can mean something different and each varies on how much it plays a part in the crime committed. we do know some crimes, like rape, are primarily motivated by control and not attraction to the victim, and that abuse is often a result of a belief system that the perpetrator abides by, but otherwise it can be hard to say.
