Yes and no

Yes insofar as the work really does stand alone - if it was suddenly revealed that Vincent van Gogh was a mass murderer, or a space alien, or a Labrador Retriever, or literally any other thing one might imagine, Starry Night would still look exactly the same.

And no insofar as I don't want my money going to a piece of shit, and to the degree that I can prevent that from happening, I do.
