BUT THEN
(a little backstory. I almost never, ever kill non hostile creatures. I will rob your a.. but I won't kill you. so it took me awhile to get bothered)
I started running into essential NPCs.
My first essential NPC was Ulfric. Because after reading that he tortured women (fellow nords even!!) and murdered every official (really>? the guy in charge of the horse tax? you murdered every minor official?)
I decided to get my Murder on. I went and TRIED to kill. I wish he was not essential. I wish that his guards stripped you of weapons when you met him and that he was always at least level 30 but NOT ESSENTIAL. Cause I woulda gacked him.
but HEY....I tell myself, he is a MAJOR NPC. MAJOR. so I was not really bothered.
I decided to help the empire, and just got like 4th quest. I decided on the way I would murder me some of those racist stormcloaks who slaughtered the descendents of brteon people at Markath.
But some piss ant no name named Sun killer is "essential" WHAT? I never even heard of him, and am like 90% sure that upon his death they could easily have assigned his part to another. that is how life works. your plumber dies, you get new plumber.
what TAKES THE CAKE...is that if I walk into their stormcloak camp...I get to kill all the stormcloaks BUT AM LEFT FIGHTING AN ESSENTIAL NPC.
I am perturbed.
