Poor poor rapist. I can't stand bleeding hearts who waste compassion on the scummiest people in society.
If you have been raped, had any close relative raped it doesn't matter why the perpetrator raped you/them, you just want them off the streets so they don't destroy the lives of other people. This guy gave the world a gift when he eliminated himself from society.
As usual, you show your amazing talent of being unbelievably slow. From the Department of Justice:
The average sentence for criminals convicted of rape in the United States (and released in 1992) is 117 months. The average time served is 65 months, which equates to 56 percent of the actual sentence served.
Old data, but likely still in the same ball park. The point is, most rapists are out of prison and back "on the streets" in 5 to 6 years. So, during those 5 to 6 years, you would rather have them be miserable, hate life, and get macked in the rear, right? As for me, I'd rather we focus on fixing whatever issues that person has, if possible, and try to mold him into a normal citizen who contributes to society. Tell you what, I'll take the second option as a neighbor. You can keep your option for your neighbor. Good luck. (although, you're so damn ugly I'm pretty sure if they threw you onto an island full of rapists who have had nothing but sodomy on the menu for a few months, they'd probably opt for the brown-round surprise.)
