psycho/socio

I'm currently working on one of my many papers and I've decided to write abour child killers. Not the lightest of subjects but anything strange and abnormal always grabs my attention. Part have my research has me showing the difference between a sociopath, which is a clinical disorder where a person shows no remorse or feelings towards others and their actions, and a psychopath, who knows what they do is unacceptable, but they need to rebel against it. I've found some interesting materials on children who have killed in the past, but so far I haven't found a strong enough case to help my argument for my paper. It is fascinating to read though. Makes me think of the idea of original sin, the idea that people are born evil, it seems unfair and judgemental.
