To be fair, the Disney of old DID actually try to adhere to classic notions of Good and Evil, and even the Dark Age and the very beginning of the Renaissance, ie, The Little Mermaid, STILL attempted to stay with that classical notion as well (in fact, The Little Mermaid arguably had a pretty neat takedown of radical feminism in the form of Ursula, who actually did state the kind of thing you’d expect to hear from a Gender Studies course regarding how men viewed women, and she was treated negatively and it was made clear to all be lies). It was around the time of Beauty and the Beast where things REALLY started going down the crapper, and even then it wasn’t until Iger got in that things REALLY took a turn to the worse.
Besides, WB’s arguably much worse on that front.
Heck, Lucas himself has a very poor sense of discernment towards evil, considering he pretty much had Obi-Wan engaging in nihilistic stuff in ROTJ and ROTS, not to mention, you know, modeling the Rebels on the Vietcong.
I remember reading an article some time ago which pointed out the subliminal messages in Disney productions over the years including the Little Mermaid.
