I was taking German in Jr High and the German teacher decided a good exercise was for us to translate the original Grimm’s fairy tales. HOKEY SMOKE, I can see why Disney sanitized them. Those things are serious, kids getting their thumbs cut off and all kinds of nastiness. Quite the shock to a brain that had been raised on the Disney versions. Of course she was from Germany, she grew up on the real thing.
There was usually a reason though, for the violence. It was usually the end result of children doing something they shouldn’t have been doing. The world was a more dangerous place for kids when they were written, and the stories warned the kids of that fact.
Think of the Fairy Tale as the pre-1850 version of Sci-Fi
