Mikulas Black-Blade
The Cave Bear
First, Torygg was challenged and he lost. Call it what you will, but that's what happened. Now, The killing of Torygg was not to scare people, it was to set an example and to send a message. That message being "If the High King can't protect himself how can he protect a kingdom?"YES you did you so freakin did. Ulfric killed Torygg to make an example out of him, Ulfric took Whiterun for same reason.
That is TERROR.
Second, And again for the third time, Balgruuf had a choice and he chose poorly. He chose the comfort of the Empire over the soul of Skyrim. That's why we took Whiterun.
