The nature vs nurture argument is not going to be settled by one book. I can see if you raised some shitty kids how the "it's mostly nature" theory would be attractive. I believe it's a combination of both nature and nurture.
However, nature feeds into nurture and not the other way around.
Is you tried raising a disabled child or one with extreme variant of personality you would know that such conditions tend to enact sets of behaviour in the environment and parents. Generally not conducive to proper upbringing one way or another.
