Almost every Disney movie have the childrens parents being killed, the Swedish childrens author Astrid Lindgren (very popular in Europe, I don’t know about the US) wrote a story called The Brothers Lionheart where the young brother is dying from an incurable respiratory disease and (spoilers) his brother dies saving him from a house fire. The he dies from the respiratory disease.

My point is that children are being told stories that we wouldn’t consider for children all the time. And that isn’t even considering fairytales.
