Then it fails at what @pemerton says is the goal of ideals. You can't tell whether that person has any particular moral compass direction. Worthless ideal.
I'm sorry, but how do you figure?
@Helldritch point is that you can use the same two ideals and differentiate them only by alignment. Therefore:
"Hunting down and killing every foe who ever raises a sword against the weak and salting the earth behind you," LG
Would be different than
"Hunting down and killing every foe who ever raises a sword against the weak and salting the earth behind you," LE
However, I can find no functional difference between these two points. They are doing the exact same thing. @pemerton 's point is that looking just at the ideal (you know, the hunting, killing, and salting) tells you about the persons moral compass. Which it does. It tells us far more about this person than we ever get from writing LG/LE next to the their name.
Unless you can somehow show me how LG differs from LE in this manner of hunting, killing and salting.
That might be because it wasn't a defense of alignment.
You seemed to be putting it forth as a bandage for serial killer paladins, because "Gygax Said" as though that somehow makes him right about how we treat things in the modern day.
Aaaaaaaand you've also made my point. If you have to go beyond the ideal to figure it out, it has failed as an ideal to show anything to do with the PC's morals.
It is not a worthless ideal, because it would be attached to a character whom the information we are asking about would be automatically provided. In a non-white room situation, the character's faith is a known factor.
Additionally, knowing their alignment does not neccesarily tell us everything about how they will go about achieving their goal. And, like I said, even providing their alignment without their faith is incomplete, Banites are very different from the followers of Wee-Jas.
