I think it is even more complicated, because I don't think it is all that clear who or what is on each side. In my opinion I think you have to add a layer of gray areas or what Harry likes to call "cat's paws." Take the Red Court Vamps, yeah bad actors but were they any worse than the White Court Vamps or the Jade Court Vamps?
It depends on your metric. It's kind of like asking whether Marcone is better or worse than his less competent predecessors in the criminal world. If you measure by the level of direct violence, especially against kids and vulnerable people, he's better. OTOH, he makes crime pay well, and the drugs and vice and other trouble he traffics in makes life in general worse, from that POV he's worse than his predecessors
because he's more efficient. If you're a street cop you're less likely to lose a fellow officer to violence with Marcone running stuff. If you're a drug enforcement man, it's far worse and you're more overloaded than before.
The vampires are like that. The White Court is easier to battle than the Red. The Reds are more physically and immediately dangerous, and they can convert you into one of them. The Reds can reproduce far faster, one Red can become hundreds quickly. WCVs need just as long as we do to increase their numbers, and are relatively much easier to kill. Lara in a nasty mood might tear through a SWAT team, but she won't make them into WCVs, and if they keep their head they may take her down.
The Black Court is worse on every metric, except that their weaknesses are so well known.
What finally brought about the downfall of the Red Court, wasn't so much that they were evil, but that they were being used by the Enemy towards a goal.. Now one could argue that they miscalculated, Bianca's actions triggers a series of events which led to a premature war against the White Council, etc, etc, which finally led to Harry's reverse family curse that wiped out the Reds..
It wasn't Bianca's actions. She was a pawn on the board, even for her own people. Bianca wasn't the sharpest tool in the box.
But was it a miscalculation? The Fomor have now stepped in to fill the vacuum left by the Red Court, in some ways they seem to be more powerful and much more clever than the Red Court ever was..
Now
that is a very good question, actually. I don't down that Somebody was using the Red Court as a pawn on the board. Some of them might even have realized it, but I think the Red King was so caught up in his own wonderfulness that he never suspected. I'm not at all sure who that Someone was, though.
I'm also not sure that things worked out just exactly as that Somebody intended. Whoever it was may have intended to destroy the Court. But the chain of events that led to
Changes is so contingent that it's hard to imagine it being planned out in detail. It requires Maggie, who stems from that ill-advised sexual indulgence back in
Death Masks. But that requires Harry's unbreakable shield, the magic rope, them being trapped there under those circumstances, etc. There are about 194,348 ways that situation could have played out differently: no Maggie.
I simply don't believe that every detail of everything that's happening is planned out years ahead of time by the villain. Not even Mab can do that. Instead, I think the villain(s) are really really good at improvising as they go along, they have a plan, yes, and they have a lot of foresight and contingencies worked out, but they still have to wait and see like everybody else. There are just too many ways things could go sour for it all to be One Big Plan.
For ex, imagine if back in
Summer Knight, when he escaped Aurora's quicksand trap, instead of ending in the tree, Harry had slammed head-first into the trunk...and was instantly killed. It could easily have worked out that way.
Suppose on Demonreach, Karrin's bullet simply blasted through Maeve's body non-lethally, leaving her wounded and helpless but alive. The whole subsequent sequence of events changes. Or suppose Karrin's gun jammed. Etc.
The enemy is powerful, knowledgeable, and obviously superhuman in some ways. They have access to broad sources of information, but I don't believe that they can plan every detail ahead of time.
So what if the down fall of the Red Court was no more than a "sacrifice fly" for the Enemy designed to advance the on base runners, even scoring a run..
I think it may have been more or less that. Whether they planned the Fomor, or just figured that the vacuum would be filled by 'someone' and they'd play it as it lay is a good question.
