CMV: Psychopaths aren't evil, they are unwell

Poorly-managed psychopathy can cause some people to behave in terrible, evil ways. However, not every person who is diagnosably psychopathic is evil- in fact, most of them are much like everyone else, they just have brains that are wired differently in a way that is understood for a lot of other illnesses. Psychopathy, recently re-labelled as anti-social personality disorder, is a disregard for social norms and difficulty empathizing with others- this can lead to harmful behaviour but more often leads to avoidant or apathetic behaviour, and psychopathy is a lot like depression in this regard. People mistake empathy (feeling what others feel) for compassion (wishing others well)- a psychopath is not empathic but can be compassionate, and it's ultimately compassion which is more important.   


There are evil psychopaths. But in general, most psychopaths are not evil- they have an illness that, if treated, needn't prevent them from living a fairly normal and ethical life.

The problem with this type of thinking is that it means that nobody is responsible for anything.  Everyone is always acting in accordance with the electrochemical machinery of their brain.  Anyone doing ANYTHING evil would just be doing it because of how their brain is wired.

Have someone who is a "good guy"?  Maybe their brain is just wired to enjoy other's happiness more so you can't give him credit for doing selfless act because he is just acting in his own interest.

Mental health diagnosis is pretty rudimentary and is almost entirely symptom based (it'd be like giving everyone that had a cough the same diagnosis without understanding the underlying conditions) and then putting everyone with that symptom or combination of symptoms into categories.  As we learn to actually understand more and more of the brain, we could get to the point where we could understand any action by anyone.  But just because we can label it and understand why their brain worked in an anti-social way in that particular instance doesn't remove responsibility unless you're prepared to say that nobody is responsible for anything.
