Indeed. Paralyzing your foe that they cannot even bite off their own tongue to end their suffering is the best revenge. They'll be locked in their own head, unable to walk in the sunshine, to play with a dog, to pet a kitten sleeping in their lap, never again to have birthday cake with a loved one, never to help make Christmas dinner, to never embrace a lover, to never know release until their life support fails.
That... is revenge.
