Seems to me Bethesda failed the evil overlord test.
The no 1 rule of the evil overlord list should be:
After years of fighting the rebels and finally capturing the rebel leader with much bloodshed and death, I will execute him FIRST, before any random, unimportant hirelings. Problem solved.
It's a small thing admittedly, but everytime I see that anonymous stormcloak being dragged to the block while Ulfric watches I cringe.
PS I tried to link to the wikipedia page to explain about the Overlords list for those who have never heard of it but it wouldn't allow me to. Apologies

) I have to watch the execution again. And every time I wonder what the hell is Tulluis thinking? You got the rebel in your clutches and you don't execute him first? Having said that if evil overlords really stuck to the rules there wouldn't be any hero's left alive in any story.
