Ok guys calm down. I guess the point is clear. Arvin, with your last couple of comments you are agreeing that he is pretty emotionless. And in turn you are agreeing that he isn't some kind of fighter for justice (which is why its still being debated here).
In your own words, 47 is neither good nor evil. He does what he has to do. Not for justice, but simply because its what he does.
-I'm almost finished with the first novel now (Enemy within). Its a surprising good read. If you haven't read it yet I recommend it.
