Read a really interesting article in the independent today about Simon Baron Cohen's theories about empathy. He looks at the effect of testosterone overload on a embryo and believes it can lead to a zero empathy negative or zero empathy positive mind. The zero empathy positives are people with aspergers or autism who entirely lack empathy but tend not to deviate from moral/social rules and so are no danger to others. Zero empathy negatives are the people who hurt others, rape, murder etc.
I thought it was fascinating because it seems to imply that those who do "evil" acts are genetically incapable of moral choice.
This got me thinking about A Clockwork Orange where the question of "woodness or goodness" is raised. If we could prevent this zero empathy negative condition should we?
