I think she was a victim - however wealthy and privileged her background, she had only one purpose from the moment of her birth and that was to marry well and produce heirs. For a woman of intelligence and character that must have been suffocating, even in a relatively happy marriage. But to be married off at 17 to a man who did not appear to care for her, who had numerous affairs and moved in his mistress (also Georgiana's friend, it must be acknowledged) was never going to make for a happy ending. She was definitely a victim of a society where children were the property of their father causing her to suffer exile from her children with the Duke and the forced relinquishing of her baby by her lover. The Duke meanwhile kept all his children, including the illegitimate ones, within his family. Ultimately it was all these children who were the biggest victims.
