Castration
That would be easy for them. Rapist who get away with their crime will soon rape another. Cut their penises and legs and arms and let them live if they can. Or the government can blind them but also provide them a rope if they want to hang themselves after it. I think this is a better punishment for such crime.
What a cruel punishmemt. I agre with castration. Once you cut it, its like ending their lives too. How can you live without it. That is one thing that makes them happy. This could be a substitute for death penalry. At least, they were given a chance to live.
