But temperament and things of that sort are still nature. A person's entire personality is NOT based on nurture, but a lot of it is also based on nature.

For example, dogs make good pets. For hundreds of years humans carefully selected the more obediant dogs and bred them to create a race of obediant pets. Most dogs, when you feed them, would never bite your hand. Most dogs wouldn't decide to maul their owner one day.

However, if one of us were to get a newly born lion cub, and raise it exactly as we would a dog, or a wild hyena pup, we would be fools to believe that we could safely feed it, or safely take it in public with us after it grows up. They have an inherent nature for violence, and you can't nurture that out of a creature.

It is very happy and nice to believe that people and creatures aren't born with parts of their personality decided, and anyone has a chance to be whatever their parents raising them want them to be, but it's naive. Part of a person's disposition and good nature are decided before they are born, as an element of their genetics. Sometimes 'good' families raise a 'bad' child, and sometimes 'bad' families raise a 'good' child.
