Psychopathy is a mental disorder characterized by a lack of empathy and remorse, shallow emotions, and a tendency to be callous, manipulative, and ruthless. Some people believe that psychopaths do not feel their own pain; however, there is evidence to suggest that this is not the case.
Anatomical Evidence
Studies have found that the brains of psychopaths show a decreased response to pain when compared to the brains of non-psychopaths. This suggests that psychopaths may have a reduced ability to feel their own pain.
Behavioral Evidence
Despite the anatomical evidence, some researchers have argued that psychopaths may still be capable of feeling pain. They point to the fact that psychopaths often display behaviors that indicate they may be feeling pain, such as wincing when injured or avoiding activities that could cause them pain.
Conclusion
Overall, the evidence suggests that psychopaths are capable of feeling their own pain, although it may be reduced in comparison to non-psychopaths. It is important to note, however, that more research is needed to better understand the extent to which psychopaths experience pain.
