I can not even count how many times I have been adventuring and NPC's start killing each other at random. If I lived in Skyrim I wouldn't leave the house with out a mercenary lol. Have you guys also noticed a lot of random NPC's killing each other?

It's essentially kill or be killed once you leave the walls. I see bandits fighting soldiers, Imperials fighting Stormcloaks, Thalmor executing Stormcloaks, vampires eating Vigilants of Stendarr, etc. Everyone in Skyrim wants you dead, and everyone else dead, too.

Well the Vigilants were dead, it was night time, and the Vampires were crouched over them. I just assumed!

Yeah well its the survival of the fittest. Kill everybody you see, and they cant kill you. I usually murder every [censored] in the big towns FOR FUN

Essentially yes. Exactly that.

I was coming north to the road along Lake Ilinalta, just west of the big ambush rock formation, when I saw a Thalmor Justiciar loitering. I engaged her in conversation (having my mace out, ready to rumble) and thought she was alone. Well, after a mounted hunter ambled by giving us a wondering look, she declared I should die a heretic's death and started swinging.

Almost immediately her partner showed up (how had I overlooked him?!) but then something funny happened. I mentioned the "ambush rock formation." Those of you who have traveled this road will be familiar with the many scenarios played out at this location. As the two Thalmor attacked, one became wreathed in flames while a large shape loomed behind the other. It was the "Imperial" orc and his two buddies! They ground the two justiciars into a pink mist, then turned about and strolled back across the road, taking no notice of me.
