Beware of bias
If you believe meta-stats on these things (and I kinda do, with caution) most of these offences are not reported at all (social and family pressure, there's a whole lot of litterature on that). Statistics (should) only look at closed cases with a conviction (to avoid unfounded witch-hunts).
It follows that the only people monitored for that kind of offences are prior offenders. The aforementionned social pressure also makes it much easier for victims to report abuse once the offender has been outed by another victim.
So of course the rate of recidivism will appear high, compared to the mostly unreported "Primo-offenders". That's just basic math. It's also quite sad. Still no reason to think that " it is highly unlikely that they will stop.", as you put it.
