If I Ruled The World...

...rapists would be castrated. But before castration, they would be buried neck-deep beside an ant hill, their manhood coated with honey and sugar*. Then the rape victim would have the honor of chopping the organ off, and feeding it to the rapist.

*Of course, this is just one of many pre-castration treatments - or PCT. Another version of PCT would be to tie the rapist up, naked, and lightly cut his skin in the region of the groin. Then add rats for fun, a la The Bone Collector. The only thing I'm worried about is that the rapist wouldn't be able to survive the rats long enough for his male organ to be cut off and fed to him.

If anyone has any other bright, painful suggestions, feel free to comment.
