But I wanted a place where I could keep Thalmor, hurt them, deprive them of food, prevent them from sleeping, drive them insane, Make it where all they can do is say "hail Talos," and kick them out to wander Skyrim and show the other Thalmor that there is a price for religious persecution. The price is higher than they want to pay.
A) nobody likes the Thalmor. Not even most High Elves.
B )Children should be taught that some things are necessary and good. Some people need to be subjected to torment for the things they have done. The Thalmor are at the top of that list. Now, I'm not saying children should be taught the art of inflicting pain, but they should know that some times it has to be done.
C) The tortures would be a message to the Thalmor that if they don't stop their religious persecution than whoever it is wont stop hurting them as a hobby.
Cut the stinking Thalmor's tongue out and you won't hear him/her screaming.

No, he'll still be able to say "WWWWAAAAAAAUUUUUUUUUHHHHHHHHH!".
Gag that stinking inebriated, slimy, milk-drinking Thalmor troll!
QUOTE: Yeah you can still scream without a tongue, you just wouldn't be able to from words properly.
Right. And I think the point of the exercise was to make them say, "hail Talos."
"Aaaaaauuuuurrrrggggghhhhhhh" wouldn't be nearly as satisfying.
"Hawuh Aawos". You could always make him incise the words on his flesh, that would really teach him and leave a permanent reminder.
By Ysmir, you have all become the very thing you despise!
