On the other hand I am not quite sure what these people told their kids and if one can apply the same standards. I think people used to be more cruel than they are now, for example public executions were drawing huge crowds. Also mortality was higher and people died at a younger age, especially child mortality used to be much higher. The concept and meaning of childhood was probably not exactly the same as today, child labor was quite common. As a result I don't quite know how to read the cruelty in original folk tales.

In addition to that you can't tell exactly if the Grimm brother weren't doing some editing on their own behalf.
