I don't know if I'd consider WHM "good." Lore-wise, I'd put them rigidly at Lawful Neutral.

Also worth noting:
WHM and BLM are fundamentally similar. White magic caused the an Umbral Era just as much as Black Magic did, White Magic has been used more destructively in the past, just as much so as Black Magic. There's a reason it's banned.

True. In reply to your first argument, however, as stated before, that does not judge good vs evil; that judges lawful vs chaotic. They are lawful, but their obedience to authority does not make them evil. Additionally, WHM and BLM are similar because they are complete opposites, which would further strengthen them as being Lawful good and Chaotic Evil. Plus, good and evil and chaotic and lawful is not a matter of what is good and what is bad, but what is moral in accordance with their ideologies and parallels.
