There is no surefire way to know if you were born a psychopath, given that there is no specific scientific test to definitively diagnose the condition. However, some signs and symptoms associated with psychopathy can be present from birth or early childhood, such as a lack of empathy and remorse, callousness, and a disregard for social norms and expectations. If you notice any of these traits in yourself or in someone you know, it is advisable to speak to a medical professional for further evaluation. Additionally, there are tools and tests which can be used to assess psychopathy, such as the Psychopathy Checklist Revised (PCL-R).
