My vision of alignment chart:
Lawful good - Jadwiga, Gandhi
Neutral good - Pedro, Perycles, Gilgamesh, Pondmaker,
Chaotic good - Teddy, Tamar, Tomyris
Lawful neutral - Qin, Salah ud Din, Victoria
True neutral - Mvemba, Tokimune
Chaotic neutral - Cleopatra
Lawful evil - Philip, Chandragupta, Gorgo, Genghis
Neutral evil - Catherine, Harald, Alexander
Chaotic evil - Shaka, Moctezuma
Explanations
Lawful good - Jadwiga, Gandhi*
Jadwiga is young girl saint, most innocent character in the game
Gandhi is obvious with his moral philosophy, and go away nuke meme, I loathe it even more after realizing it overshadows IRL Gandhi's serious teachings.
Neutral good - Pedro, Gilgamesh, Perycles, Poundmaker
Those guys are either progressives or friendly and loyal, without "sanctity" of lawful good. Perycles maybe would be lawful good if not my memory of slavery and misogyny of ancient Athens
Chaotic good - Teddy, Tamar, Tomyris
Teddy is amazing as chaotic good character, crazy badass but also very sympathetic. Tomyris is prety much the archetype of "honorable barbarian".
Lawful neutral - Qin, Salah ud Din, Victoria
They want to strengthen their civilisations by following legal framework, but that legality may be occasionally unpleasant to their enemies.
True neutral - Mvemba, Tokimune
They just want to be left alone, maybe except merchants and missionaries.
Chaotic neutral - Cleopatra
Scheming, flirting wild card, with both personal and country agenda in mind.
Lawful evil - Philip, Chandragupta, Genghis Khan
Philip is man following laws and conventions but also somewhat arrogant and definitely fanatic and warlike. Chandragupta wants to create law and order by beating all nearby weaklings. Genghis somewhat respects law, order, loyalty and diplomacy, and then horribly murders those who do not and ravages their people.
Neutral evil - Catherine, Harald, Alexander
Those are egotic jerks. Catherine will betray anyone to get power for herself and maaaybe her realm, Harald is brute warrior, Alexander loves war for the sake of "glory".
Chaotic evil - Shaka, Moctezuma
They simply want war for the sake of war. Strong tramples weak, war is lulz, bloodshed is glorious, gods are pleased.
Gitarja, Jayavarman, Robert and somehow Traian I feel I know not enough about to rate.
