I say creatures, beasts and monsters because that's what they are. When you participate in the gang rape of a 15 year old girl you are no longer human. Perhaps I shouldn't say beast, either. An animal doesn't understand the significance of its actions. These creatures do--hell, even if they don't, you still put a mad dog down. As such, I don't feel that torturing a rapist or a murderer is the same. They aren't human. They aren't animal . They are monster. What happens to monsters in the movies? Eventually someone corners it and destroys it violently. The vampire is staked to the Earth and left to fry in sunlight. The werewolf is shot with a sliver bullet. The zombie is decapitated.
By extension, let's begin eliminated the pedophile monsters, the serial killer monsters, the gangbanger monsters and so on. If we haven't the guts to eliminate them, let us at least keep them under lock and key for the rest of their lives.
Why the innocent women? Why not punish their tormentors in such a way that future crimes are greatly discouraged? Yeah, you can't take back what happened to those women, but you can prevent it from happening the next generation by setting a clear example that this behavior will NOT be tolerated.
