I'll get back to the rest of that post later... but that left me sputtering in shock. Mab's ready made built in to know she logically can't go too far without invoking Titania's doomsday device. If she were the scorpion... the scorpion didn't wait or anything really, it just did what it does. So Mab would have already just tipped the scales and got drug into oblivion if that was her nature. The thing that changed was the fox, it gave the scorpion an opening despite it's knowing better. So she can't just 'go too far' without a precise change somewhere in that balancing act of the connected courts.
And the metaphor to the WC or RC is the consciousness and the demon which are also connected can't just change the dynamic of said balance without farther change, change in any creature implies choice. Reds already killed, if there were no farther changes then they'd all be as Susan, and never adapt into a more comfortable life with it. At the very least they keep what remains and must grip it tight to prevent the slow spiral into being just what they look like on the outside. Tangent over, I think lol.
No, lets stick with this, because this is the actual crux of the topic you are on.
In the Case of Whites, they are "half-born" and that's all they are. In the case of Mab, oh my no she could, and Would, Absolutely murpder every single human being on the planet if she deemed it necessary to fulfill her duties. That is entirely within her Nature. What would require a Change on the order you are imagining would be, per the WOJ that started this whole issue, "She /can't/ show up and suddenly be merciful, generous, patient and kind." She can absolutely remain a cold-hearted bitch that would slaughter millions, the only thing stopping her is that doing so would hamper the defense of the Gates by long-term attrition or by the disruption while the new Lady came up to speed; but if either of those two external forces were to go away and she thought it was worth it she could end the human race and sleep well that night (barring other/outside opposition of course).
Now where were we..See above for part of that. But again, that would say the 'being' known as the Red King basically resisted what he really was for over 3k years. Resisting what you already are by our 'slow decay to natural state' theorem implies he made a conscious decision to do so for all that time.
Wamps let something in, Ramps become something in body and Blamps are replaced entirely is how it looks to me.
There is a vast difference between Loosing your Mind and Gaining a Soul.
In the case of full Reds, they have been entirely transformed into a soulless creature, that basically just happens to use human beings as incubators; this isnt much different than the Black Court that are some sort of necromantically animated corpse. But their core Nature is that of a Predator, and that has not at all changed when one falls to being a Blood-slave. Had a Rampire attempted to go Vegan (somehow...?) or otherwise rejected their core nature, that might constitute a fundamental shift. But the core of a Rampire is just the predator, theirs nothing innate to Vampirism that says you have to be a /smart/ predator, which is the only difference between a normal controlled Rampire and a blood-slave.
The analogy my mind goes to is drug addiction (thank you Elementary binge): A Bloodslave is the equivalent of an Addict that has fully succumbed to their addiction and OD'd, whereas a normal Rampire is just an addict that is still trying to hang onto their Life (socially speaking) and hasnt yet hit Rock Bottom. Neither of those indicate the sort of fundamental /reversal/ required to actually overcome it.
Look at the other side of the line: Thomas actually exercised his Free Will for a while trying to entirely deny his Wampire Nature to the limits of physical survival. Lara has just built up an empire that makes Hunting Easier but will likely never even consider that she actually /shouldnt/ feed and even kill for any reason beyond the logistics involved. Meanwhile, per WOJ they have a sister locked in the attic that is "utterly bonkers" which I expect is a reasonable White Court equivalent to a Bloodslave.
*looks obliquely* now your just theorizing. On something disputed already btw(human or fae? no soul no choice?) we're still waiting on this one guy.
Have you read Cold Case? It's pretty directly shown there multiple times.
Bob's a full denizen of the mortal realm with his own mortal body? Extraneous details, not really sure what this is supposed to prove.
Im also not sure where this was going, but fwiw Bob is neither of those things.
