I am merely using it as an example. The Nazis used fear effectively also. It really doesn't matter timewise because its simply human nature. As for violent resistances to the queue policy, well you can see which side is the clear winner. If you feel that 0 resistance is the only measure of success of a policy then I concede the argument.
The structures you deal with in-game are very different with what you field as examples. The general population will obviously be influenced by fear, but counts and dukes, who are able to field their own armies, will be less likely to tremble with fear because some poor soul has been decapitated. And even normal peasants will at one point change their approach to intimidation, as soon as they feel they don't have anything left to lose, I suspect.
