More that they weren't devoid of choice. They could choose to give in, or they could choose to fight it. the fighting it, if it really is a natural devolution, is a stark choice to make to me.
I think it boils down to the idea that they only get that Choice the once, specifically at the point where they Kill; after that they are just dealing with the fallout and consequences of that Choice. Changling style, to my mind.
Relevant to the denarian topic, I think Susan could wield the Sword as a half-ramp but would not be able to after the change even setting aside the Rampire issues with articles of Faith....WAIT A MINUTE!
Would a Denarian Coin count as an Item of Faith against creatures with that Catch like Ramps and Blamps, like some sort of evil Holy Water?
Not everything on the mortal plain possesses a human soul, but that doesn't mean they have nothing. Tera being a relevant oddity, Did she not make choices and adapt at times? She choose to make the Alpha's yes? Granted I think she's totally a bad guy in FM, but that's just my crazy idea's lol.
This is where the Free Will conversations usually get bogged down, as it falls into the long-established philosophic pit of divergent definitions and/or levels of Free Will as opposed to Setting specific issues. So, take all the following as just the best DV fit Ive seen, but not anything like a settled answer (easier to find bigfoot riding a unicorn
)
The distinction comes down to the idea of Philospohic
Agency, as compared to the DV style Free Will. Mab and Bob and Tera and anything soulless can freely Act and interact and make day to day choices in response to their environment. But they will always act and respond according to the same script (ie Nature); they are on the
Deterministic side of the AI debate. Mab can plot and scheme, and can react quickly and out-think most things that exist, but she will always react the same way given the exact same history and circumstances. Mab is more rigid that some because of the additionally rigid nature of Winter, as opposed to Summer whose nature is to try new things and see what sticks rather than plot a glacier course (This is why I think Mother Summer retires but Mother Winter does not, fwiw).
The best example was to compare Mab to Lucifer. Both crazy powerful and entrusted with specific cosmic Purposes. Lucifer was given a Job and (presumably) a specifically designed personality to accomplish that Purpose. But he also had a Soul, thus Free Will and thus a (single, shitty) Choice: he could either stay On-Script, or else Fall and ever-after be able to exercise some amount of Free Will (since any Act of Free Will by an angel is by definition rebellion). Popular theology is that this was never part of The Plan, but Lucifer could and Did Choose the Left Hand path, and the Universe had to deal with the consequences. By comparison Mab physically Could Not choose to go Off-script in the first place.
