It is quite interesting to learn about the deterrence curve and how it flattens out quickly when the most egregious comes are involved because most people are already really likely to shun away from those crimes due to social norms and moral issues. This actually reminds me of something I learned about forensic psychology, so if the suspect is mentally ill and not able to control his/her own behavior, then the forensic psychologist would make a psychiatric assessment of that person to make sure it is the case, then he/she would just be sent to a mental hospital instead of being incarcerated. In other words, this is indirectly blaming their crimes on their inherited mental abnormality, rather than on those individuals. It is as if to say those people were born with genes to commit crimes, and their brains are hardwired differently so they are incapable of monitoring their own behaviors and adjusting to the social norms. And a lot of studies about stigma associated with mentally ill people have shown similar outcomes. Although the public is becoming more and more lenient towards people with inborn mental illnesses, they still more or less show discrimination against them in terms of job hiring, school acceptance etc because deep inside their minds, they think those people are incurable. On the other hand, there are some extremely evil criminals who would try to escape from justice by faking a mental illness, which sometimes could be hard to detect. I guess my question is whether or not we should treat those criminals equally, regardless of their mental states.
