We could assume that Vermouth's words:
"We can be both of God and the Devil. Since we're trying to raise the dead against the stream of time."
meant reviving Renya, the true Anokata. But since he was a bitch, and Vermouth knows that pretty well, she's against the idea of reviving him, and that's why she sided with Conan and his BO's destruction plan.
My dad’s a soldier blue I’ll be a soldier, too
When I grow older you will see me rescue you
I’ll teach you this old song so you can sing along
When I am dead and gone the day won’t be so long.
