Three axis alignment, revisited

I have seen a couple different suggestions for adding a third axis to alignment. One suggestion is to add an active/passive axis for how militantly a character pursues their alignment. Another suggestion is to split the lawful/chaotic axis into two axes for internal and external attitudes: a chaotic/orderly axis for a character's behavior and a lawful/lawless axis for whether a character respects the laws of society.

City of Titans is a example of this: their alignment matrix has three axes of peaceful/violent, honorable/pragmatic, and lawful/lawless. This is independent of whether a character is a hero or a villain.

The Radical Re-Alignment supplement by Plot Device takes this to its logical extreme by including no less than six axes for alignment to give characters much more nuanced approaches. None of these strictly equate to "good" or "evil."
