double dyed donkey

this is in Henry James’ THE GOLDEN BOWL
there is no documentation of it on any of my favourite etymology or slang websites.
i wonder what it means
anyone know?
here is the context:

“There were beautiful intentions all round. The Prince’s and Charlotte’s were beautiful — of that i had my faith. They were — I’d go to the stake. Otherwise,” she added, “I should have been a wretch. And I’ve not been a wretch. I’ve only been a double-dyed donkey.”

i think i know what it means and i think i have been one myself recently
in the complex interstices of love
who hasn’t been, really?

pat has a cat scratch and we went on a brunch date

the bloody mary kind of is gross near that short fatty ketchup, huh?

we took lots of photos of this bizarre little dude trying to poo

he couldn’t do it
his butt was too cold from being ingloriously shaved

this is pat’s dirty butt from going to a Dead Moon show in New Jersey and falling down a lot

we biked to LIC to see THE OPEN before it came down!

they were setting up an event so there was a lotta junk kind of ruining the views

bad place for a trash bin. puts the idea in your head you know what i mean?
