Any particular reason someone can offer why these rapists deserve to live?
I know in our PC/multicultural/celebrate diversity era it is impolitic to state the obvious, but here goes: These are not men. They are animals. They need to be put down just like dangerous wild beasts.
I got a much better form of punishment. Put them in a large cell-complex with a lot of big inmates who will ask them nicely 'to pick up the soap that was just dropped' many times a day. Tape it and show it to their fellow 'Leb-stylers' so they will be not tempted to do it too.
