I keep meaning to post a lenghtly discussion about alignment, but I keep getting too busy. Basically it goes like this: Alignment only works in d&D because the character have an external control, namely the players, that know what they think is lawful, or evil, or good, etc.
I think a D&D game can be set up where the LG types still slaughter the orphaned kobold chidren and still be LG.
Further, imho, people will act differently based upon different situations, a person that is normally LG might to a very evil act in the correct situation. Given that I think it would be very very hard to find nine people to fill the slots.
But, here goes anyway:
LG - boy scouts, well, ideal boy scouts. George Washington.
LN - Any competent career enlisted (non-officer) soldier in a modern Western army. IDEAL judges.
LE - Ambulance chasing lawyers
NG - The Amish
NN - ???
NE - Stalin, Saddam Hussein
CG - Johnny Appleseed.
CN - Hell's Angels
CE - Jeffery Dahmer
