This 100% you cannot compare Nathanos to Nazgrim in anyway. First off, Nazgrim wasn't a pathetic self insert of a dev who had a hardon for one of the lore characters. Cough Steve Danuser Cough
But like he said, Nazgrim believed in things like honor, nobility, duty. All Nathanos cares for is serving a wicked ***** who he knows is evil but doesn't care. His entire character is "how do I make my waifu happy!" His writing is terrible, his plot armor is terrible, he is terrible. I can only pray we off both him and the Simp Queen in Shadowlands.
