The negotiation will be more beneficial with a scale, based on traded info, that more resembles:
"Your life is over"
"Your life is over until you are retirement age"
"Your life is over until after you go through menopause"
"Your life can restart before you're 30"
Or, you know, just hang tough and get no dirt.
Truly beneficial scale would simply be: "You can return to regular society with restrictions after you have been rehabilitated, and you can return to regular life after your victims have been compensated."
The other thing that's bothersome about these showy sentencing standards is that it provides good cover to the regulators and legislators who should be auditing their past actions with respect to this enterprise and should be holding honest hearings on how the legislation failed to protect consumers.
