You know, the paladin code of ideals that are supposed to be embodied by those sworn to the light IS antithetical to Arthas’ actions. I had not considered that.

So perhaps one could say that the cold pragmatism of his choice would not have been wrong for an ordinary general to make, but was against his code, and betrayed a weakening or abandoning of his faith.

I still don’t think he was wrong broadly, but I think I agree with you that he was wrong with regards to being a paladin and a representative of what they are supposed to stand for.
