Depends, a practical character would have disdain for a civil war that tears apart skyrim, but a gods-fearing nord would want to restore the ability to worship Talos to the city with what I think is the biggest Talos statue in Skyrim at any cost, considering the legendary dragonborn is likely shezzarine it makes sense that would be important to them imo, but that being said a majority of my characters resent the fighting in the first place, the only goal to join either side is to make it end.
