As always, everything that happened is Rei fault too, albeit fault it's not exactly the best term.
There is something that i already noted more than once that Goddess Gold forgot.
She is Goddess Gold.
Facts are, for all her proud and pompous facade, she pretty much gave up on doing something.
When i said waiting for a miracle, i meant it.
You can see with her EXP, that she literally hoarded waiting to use it.
Waiting to improve, waiting for White, waiting for something.
She didn't believe she could change the situation and simply gave up on doing so.
And no, this isn't something "unavoidable", as Amanda for example kept fighting impossible odds and going after VIP target well after losing everyone.
Everything Rei suffered through?
Amanda went through worse.
Family killed? Yep
Someone important went of the deep end? Yep
Hell, Gold doesn't even have the "My best friends and pillar of mental stability were killed, and two of those were actually stapled together like a piece of modern art,
while being alive" thing under her bell, nor the "everyone i love and don't dies".
Red Rose was scarred, broken and everything in between regardless took an apprentice under her wing and decided to help a young magical girl knowing they would both die before her.
Did she magically healed from her problem? No, but she didn't roll over and waited for something to change but gritted her teeth kept fighting and fighting.
Let's ignore the "just after Hope" time where she could have stopped White.
If Gold decided to bring White back into the fold, with overwhelming firepower if necessary, she could have done it.
The Counter Force would have been more than happy to track down another Goddess desperately needed or Gaia would have leaped at the change to help her most successful children and at the same time crush Shiva plans.
Take back White, spank the everliving shit of her and Ni for everything and crush everyone in their way was possible even without Solid Core.
Easy? No, it could have easily failed.
But the EXP bank shows clearly how much she tried.
IIRC the worse starting point for the quest have all the goddesses dead, so this give you an idea of how things actually went without aside from doing nothing until someone killed her.(This is more for the other poster as, well, you know how the would go in the worse scenario for obvious reasons)
How i have no idea, considering Red is solidly in UD team.
Seriously, if she decided "Fuck it,let's go full White Kingdom and take back what's mine" she could have changed the war single handily without us.
She had ways, albeit it could have gone wrong.
I'm not saying she is in the wrong, the fact she is still fighting under such situations is big, and expecting one person to change the course of a war in such a way is simply unfair, because she is not anyone saviour.
Rei Mitsubishi is a goddamn person,not a shounen character and not Shirou.
But Gold, as many others, isn't simply a poor victim of the situation
Because yes, with great powers, everyone is your responsibility....but with great powers,
you have great powers.
Or as Rei would put it
So don't feel too bad, she isn't Sakura or Sayaka/Madoka, she's more like Homura.
You understand her, but she is still a
goddamn idiot sometimes.
