Saying that we can predict what a person will do in
most situations is to acknowledge that perfect prediction is impossible. And if that's the case, then it's because either (1) everyone has free will, or (2) a person's actions are determined, but a person is so complex that it is not possible to make an accurate prediction in all cases.
On the other hand, to say that we can make reasonably accurate predictions because we know "the person's strongest drives" doesn't actually
mean anything in terms of free will. To illustrate, let's take an example that
JLNobody used (in a post that, sadly, was lost in the last server crash): I am lying in bed half-asleep. I can either get up or I can continue sleeping. If I understood
JLN correctly, my decision is dictated by my stronger drive -- the drive to get up or the drive to sleep. But how do we know which drive is stronger? Well, apparently we know by viewing the result: if I get up, then my drive to get up was stonger; if I sleep, then my drive to sleep was stronger. This, however, leads us to an empty tautology: I get up because I got up, and I sleep because I slept.
As I have explained
elsewhere, we can, at best, accurately
retrodict events, but we cannot accurately predict them. To explain events by retrodicting on the basis of human "drives," however, does nothing but involve us in a tautology. Meanwhile, if we cannot
predict human actions, then we must either acknowledge that humans have free will or that humans are so complex that we can never know enough to know what they will do beforehand. And if the latter is true, then it is difficult to see how, in practical terms, that belief is any different from a belief in perfect free will.

While I see nothing wrong with that the guy who raped the girl did it because he couldn't resist the urge to do something he loves to do, just like I sometimes write a letter to a friend. It his inability to contain that desire that we punish. But the guy has to live supressing his true self, hiding from the law or living behind bars.
There have been many attempts to justify a system of morality in the absence of free will. This, I must say, is not one of the best.
We cannot say that a person rapes because he has no free will while simultaneously asserting that we are justified in punishing him because he "couldn't resist the urge" to rape. If he had absolutely no free will, then any notion of "resisting an urge" is nonsensical, since such "resistance" would depend upon free will. If a person is truly determined in his actions, then any kind of legal system must be based upon punishing people for doing what they do, rather than failing to do what they should have done. The former is a deterministic standard, the latter is a free will standard.
