"Surely people with no criminal record will be the most effected by harsh punishments?"
Yes, on an individual basis, after the fact. What I'm asking is what is most effective as a *preventative* measure. If you agree that the typical rapist isn't aware he's committing a crime (you might not, and we should talk about that, then), then you should also agree that the stiffness of the penalty would have no bearing at all on whether he chooses to go through with it.

"A rapist, by definition, is both a sociopath and mentally deficient."
With respect to your pedantic nature sir: no, it isn't. A rapist is, by every definition I know of, one who has committed rape.
"....every study I've read to date indicates that rapists *do* have a different mind set, typically a sociopathic disconnect..."
That's an interesting claim, Draugnar. Can you tell me which studies have said this? That definitely goes against my understanding. I'd very much like to hear what the professionals you have read have to say about the mental state of the typical rapist.
