I was watching "I Love You, Now Die: The Commonwealth Vs. Michelle Carter" last night and all this talk about mental illness talk makes me think of the extremity of nature vs nurture.  

If you are not familiar with the case, here is the wiki.

Any who, I know people who have been suicidal since their teen years and I am 44 now.  I have read quite a bit about suicide and even children commit suicide.  Suicide is definable but evil isn't really.  I am leaving that open to interpretation. The question I ask you and myself is can someone be born suicidal?  Can someone be born evil?

I think it's a case by case thing.

Sometimes you hear about the serial killer next door being the nicest guy ever that never showed any signs, and even the parents are shocked. Then the next time it happens it turns out the guy was a shut-in that never talked to anyone and his dad used to put out cigarettes on his face and watch him shower.

Same for suicidal people. Sometimes there's zero sign of anything wrong and everyone is shocked and other times it's because they're deeply depressed and couldn't get help or their parents beat them or they were bullied at school and couldn't cope or whatever.

How'd I miss this thread?

I think to a certain degree, some people are simply born evil. No one kills 6 million Jews, and isn't evil. Yet, culturally/historically we spent millennia killing, torturing, raping, pillaging and enslaving each other and committing one atrocity after the other and it's often accepted, forgiven or looked past in the name of king & country, imperialism, colonialism, religion. 

In a much more modern context, in hindsight though, there's often tell-tale signs someone is inherently evil ( usually after they've committed some awful crime, we can see it ) you know the feeling, that unease being around a certain person due to behavioural and personality traits, inflicting talk/acts of aggression, etc. Depending on where they are on the evil scale, they could simply be an arse-hole, or they could be mowing down children in a school yard. When it comes to mental health, we often don't associate/recognise the sociopaths and psychopaths as suffering from mental health problems until it's too late.
