I did and even gave how to role play the difference.
Ideal: I will defend the weak.
Bond: My king.
Flaw: Lack of humility.
Both paladin, twins if you want and one evil the other is not. I clearly shown how alignment will help differentiate both characters in their approach and yet, to "justify" that I am wrong, I am told that I twist the ideal and bond to no end... A LE is already twisted. I did nothing out of the ordinary and yet those against alignment do want to acknowledge that I did do it.
To quote myself
This exemple is a RP of two characters with exactly the same ideal, bonds and flaw. They are twins. One is good the other is evil. This is on the sheet, the only difference. Yet, the alignment gives a nice twist to the second that opponents to alignement refuse to acknowledge. If that is not enough for you nothing ever will.
I cannot see the second Paladin as "defending the weak." That might be how they
wish to view it, but by that definition, the personal armed forces of every dictator in history could call themselves "people who wanted to defend the weak." You've strained "defend the weak" until it means whatever you want it to mean.
I can certainly grant loyalty to the monarch and a lack of humility. The former has no inherent moral character (or, rather, it depends on whether the king is moral himself), while the latter only touches on morality incidentally in most cases (it's more a cause of being rude and inappropriate, not morally bankrupt per se). But I cannot accept "defend the weak" as an
Evil motive.
"Punish the wicked"? Sure, that's Neutral at best. "Destroy the destroyers and despoil the despoilers"? Almost certainly Evil. But those are different from "Defend the weak." As soon as you get into "defend the weak" being used as a justification to attack or torture or deal harm, it's not about DEFENDING anything anymore, it's about punishing or attacking or harming. That is exactly what MAKES one value different from another.
Unless you want to tell me that "we had to destroy the village to save it" counts as a form of "defending"...which, again, looks like straining the meaning of a word until you've pretzel'd it into whatever balloon-animal shape you want.
(Incidentally, the fact that I can point to this and say, "but even if you punish the wicked so that the righteous but weak can feel safe, that's clearly different from just defending the weak" is exactly WHY I don't find alignment very useful. There is a clear behavioral difference between "person who hunts down the wicked" and "person who gives protection to the Least." It is possible for a single person to do both things at turns, but it is also quite possible for them to be forced to choose between protecting a few innocents and punishing a few of the wicked...and that's exactly the situation that will show which of those values is stronger in them. Video games love those kinds of conundrums; the Mass Effect Paragon/Renegade divide could literally be summarized with "save the colonists, I don't care if the mastermind escapes" vs "damn the colonists, I won't let this bastard hurt anyone else ever again." Both in some sense heroic...but the latter pretty clearly values defending the colonists less than punishing and eliminating threats, since it MEANS choosing to let more victims die
now so that the sequence will end with them. That's a
different Ideal, even if they're related.)
