I’m sorry, are we trying to humanize Cruella de Vil? Give her a Maleficent-style “redemptive arc”? Because as I remember the story, she was a dog-murdering monster who was gleefully and determinedly trying to steal and skin puppies to make a coat. I don’t feel like there’s a lot of “redemption” available for a character like that.
Y’know, some villains don’t qualify for redemption.
