It's dumb to portray anyone who wants to skin puppies in a positive light. You can look at the time period and go "well I suppose that's a thing that happened for the time period." But that is not what is being done.
Disney isn't making a period piece; they're dressing up actors in period wear (in most cases... probably not) and then somehow trying to humanize a woman who was willing to break laws in order to murder puppies. She literally hires two thieves to steal and kill/skin the puppies after the owners won't sell, and then tries to ram them with her car. She's literally a psychotic villain.
I have no idea how maleficent became a thing people cared for; she was a jealous witch with overwhelming power that destroyed a kingdom because they didn't invite her, a witch with overwhelming powers, to their daughter's birthday?
Why are we trying to make inhuman characters human? I ask this in a void because I honestly don't think it's because they have some weird agenda to make Muslim suicide bombings noble. It's just a f'n weird quirk and I don't get it. It's shitty kids with bad parenting growing up with bad schooling who think them being stupid/weird is somehow a super power. It's dumb.
