No, you missed my point. I didn't say it was actually going to be different. With determinism that's impossible. What I am saying is that it would have been different had he turned out to be a different individual given different circumstances.
The reason why it's different from the hydrogen molecules is because in the case of the criminal, he doesn't need to be a completely different person, only a few things needed to be different for him to lead a good life, but in the case of the hydrogen molecule, the very essence of its nature compels it to act the way it does.
So, if you can theoretically go back in time and change a few circumstances, that person would have never become a criminal. But no matter what you do, this change cannot be possible with hydrogen molecules because their very nature is unchangable.
The point of determinism is not that the outcome is always the same no matter what. The point of it is to say, that depending on the varying social conditions of the individual, he may have no choice to act completely freely. At least it is the point I am trying to make. That his actions depend on pre-conditions that he had no control of. That is not to say that the pre-conditions could not have been different.
