As one does these days, I asked an LLM to help me detect if I had a bowdlerized version, and while I'm sure the stories were already softened in translation, they're still far more 'rowdy' than stories you can easily find today. In the old folk tales, things just happen. Fairness isn't guaranteed; and sometimes a guy makes a deal and gets eaten anyway; and sometimes someone dies for no reason.
I wonder if the changing narrative structure of modern stories is a result of our improved civilization. In a world where you're probably reaching adulthood with your brothers and sisters without encountering any sibling death, a story with 'unfair' death and destruction probably feels out of place. Nonetheless, I sometimes am saddened when I read people talk about stories in media and how they 'glorify' bad behaviour or 'send the wrong message'. A thing I really treasure from childhood is the breadth of storytelling: not all stories were an Aesop's fable.
But perhaps that's not true. I suspect the truth is that with lowered barriers to publishing there are just more stories told. The ones from the past that we know are twice selected: once for cultural value, and once because the writer himself was selected. Today, anyone can write, so it's the same problem as we encounter when we look at personal websites today. Sampled randomly in 2004 you would get interesting ones easily. Today, that is not so easy.
This is most easily visible with foreign media. The Chinese stories I've read are alien and strange and interesting; and the Japanese ones take unexpected turns. But they're going through that selection process as well. So it's probably just a boring selection effect.
Still, I've got the old Grimms. I'm keeping that one as an heirloom.
