You know...of all the concepts D&D has used...I personally believe that
Alignment is the worst...In every D&D game I run...I generally ignore
alignment...because the whole concept is somewhat silly...because whether it
is subjective or objective alignments...they make no sense...if I had to use
alignments...I bust out a copy of the Palladium RPG...because when they
wrote their alignments...they gave specific guidlines on each as to what a
person with that alignment is like...and I would never ever try to classify
an entire country/species as a specific alignment...I would just play them
how I felt they needed to be played...and to deal with spells and effects
which matter by alignment...If a paladin (who by the way...may not actually
be Lawful good...an example of this might be Solomon Kane from Robert E.
Howard)...encountered something whose purposes where evil from his
perspective...then I'd treat it as if it was evil...but that doesn't make it
evil...and if you try to deal with alignments as if they are objective
things where there is a way that all LG people will act...then I would
assume that every nation existing was Neutral...with tendencies...I don't
believe there is a nation in the world that you can point to that has never
done something which could be viewed as evil in some way....

Just my opinion
