Free Will - Yes/No?

[robvalue]

I thought of (hopefully) a clearer way to show the free will fallacy I was talking about earlier. It was only ever an aside, but I seem to have confused some people.

Consider this argument. I'm not trying to make this argument myself, I'm simply examining it to see if it makes sense. I am spelling out in explicit detail what is being implied.

"If it is the case that all humans have no genuine decisions to make, I think it is morally correct to make the genuine decision not to punish any crimes."

I hope this makes it clearer that it's a malformed argument. It is trying to persuade the reader to do something that it has stated is impossible as a hypothetical premise. I'm saying that if someone puts forward an argument that is formulated like this, it should be dismissed as illogical and useless. And I have heard people try and use this kind of argument.
