The Hauteville protagonist Bohemond would be an excellent candidate for Chaotic neutral. They were all selfish bastards, and most of their plots and schemes were heinous in their own right, but Bohemond merely wanted recognition and fame. He didn’t give a crap about the rest of his family, only that he got what he wanted. A truly mercenary mindset…
How about chaotic good for Jan Zizka, and chaotic neutral for Sforza?
That said, I don’t think the alignment axes make sense in the context of AoE2. Lawful according to which laws? Good according to whose moral code? Alignment only really makes sense in relation to a fixed frame of reference, but AoE2 has such a multicultural setting that there’s no clear choice of frame of reference.
I think it’s quite a misleading choice of terminology. Something like “lawless” would be better than “chaotic”. To me, “chaotic” sounds like someone who appears to act at random from other people’s points of view.
Anyone who deliberately breaks the law for a good cause is chaotic good, so for example, Harriet Tubman, Emily Davison.
