This was due to a bug, but I throughout enjoyed it.
I was attacking Rolff Stone-Fist in Windhelm again and again due to him being a racist bastard, and on one of my quickloads he attacked me first! So, he got the guards after him. Who got him down. Only for him to arise and start all over. I had a good laugh from that, until they chased him into the Temple of Thalos. They didn't want to follow him in there, so I did.
As I kicked him around in there, the 2 priests noticed and acted rather surprised that I was beating him good. But after a few fights they just started looking at the fight, and one of them even said "My money's on the big one", so I figured they enjoyed the sight.
When I got bored of him in the end, I set him to be unessential, and ended his miserable, ignorant life with a killscene shot of me piercing my sword through his stomach.
By far the most pleasurable fight I've had in Skyrim so far.

Oh, and rest assured, even though he died with a sword in his hands, Alduin will make sure that he never makes it to Sovngarde. I haven't finished Main Quest on this character yet.
