And probably will again, but I don't think any of us enjoy the pain, and use our fear to usually temper our excitement of what's cooking under that steel lid by reaching for a pot-holder.
I don't know that sanitizing away our Fears of Pain & Punishment behind politically correct privacy concepts is such a good thing - I really do wonder about public punishment and whether criminals have enough self-respect to fear public humiliations as a deterent, or a reason for their behavioral change.
Which makes me wonder if the Outings Websites affect the predators and if that threat of being publicly identified and humiliated would stop someone. I'm a far stronger support for victims' rights than criminals', and I do wonder if our sanitized privacy hasn't given the criminals enough darkness to continue their scurrying about.
As for death penalties and deterence, you'd have to ask the kajillions of people who've never killed anyone yet have probably had wishes that someone in their face wasn't on this planet any longer. I've crushed the existence out of some creatures before - beheaded one, in fact. I've slit their guts and spilled their innards out. And when I stomp a cockroach, it's true that I don't fear his radioative 50-foot Harryhausen-esque brethren will come after me but I also don't believe he can be rehabilitated. So I kill the bugger.
