I was listening to a song (perturbator) about an Ai apocalypse kinda deal, and noticed that the motivations were about the orderly harmony of all parts involved, and realized this as Lawful.
This is also how things like Ants and other hive minds work; complete harmony with one another as part of a giant machine; which is essentially what Bureaucracy and laws are meant to do in the grand scheme of things.
Any thoughts on whether these hive mind style organisms should in general be treated as Lawful instead, given their orderly societies?
Seems to me that having an alignment implies a concious ethical decision. Ants aren't orderly because they believe in order, they're instinctively orderly.
Yes. An Int score of 3 or higher is required for self-determining your own alignment. Otherwise, you will have to rely on alignment subtypes, like native ant creatures from a plane of Law.
