No, I am not, but I am also not into letting people take a lesser punishment than deserved. Death is just that, they die and that's it, but putting them through the same thing they inflicted would force them to suffer exactly what they forced on others and would not end in one instant. The elves didn't just die the second they were enslaved, they were put through much hardship and pain, sometimes just physically, but often sexually as well. They suffered worse than death, so their assailant deserves the same.
