I would think the person to suggest this completely bonkers...until Dragonborn

I'm gonna have to go with no. Sorry bud. I think that if Ulfric really wanted to impress people, he'd just go along with the story and say he shouted him apart. But he told us that his feat wasn't quite as impressive, and I don't see any reason for him to lie and give me a lamer version of the story. If one was to say Mora's influence, I'd be inclined to disagree, as I'd think Beth would give us a hint to this or something.

So what if he is? Mora isn't evil, or anything.

People need to get rid of the idea that the Daedric Princes are all devils or something. They're amoral. Just like the Aedra. Only difference is they're not influenced by mortal belief, so they don't have to give two [censored] about the people on Nirn. The original Aedra were disgusted by creation.

Maybe go into Dragonborn section? I know it's about Ulfric and all but....eh.

He's not evil...
Just a complete [censored] that tends to impale people with tentacles

Doubt it. Unless you think the Greybeards worshiped Mora too.

Oh god, it all makes sense! Mora created the Dragonborn!!oen1/!

*Face filled with utter shock*
It does make sense...

Maybe not technically, but from a mortal's point of view he would be, depending who the mortal was. From the Skaal's perspective, he's definitely evil. Thats all evil is. A point of view.

Well they have a good reason for it,

Then it doesn't exist, thus he's not evil.

Not really, haha.
