But even if you accept that children's lives back then were particularly brutal and this was in fact meant as a children's book: there is no evidence to suggest that exposing children to brutality in books will somehow help them function in a brutal world. If anything, I would think that such children especially need something "beautiful" in their lives: the fairy who comes with good advice, the dragon slain in the end, the lost child who finds their way home. A bit of hope.
But I'm not a pedagogue, just a dad.
Did they prepare me better for life? Nobody can answer that without time machine. For certain they didnt instill any trauma, you need real world for that and not fantasy. Dont treat kids like some fragile porcelaine dumb beings, they grok most of real world fast, see all the bad parts and can handle it way better than overprotective parents like to admit. They often cant express their thinking effectively but they see, hear and understand most of the adult world well.
I certainly read those stories too to my kids.
And I've read gorier stories from damn Catholic journals for late aged kids in the 50's -from my parents, as they had tons of distinct books- will full depiction of beheadings from God's will in Africal trives and whatnot that would set a straight +18 sign in the cover today.
So a 14 year old in the 1960 could one-hit KO a current 18yo kid from today in the spot because they had drastic hormonal and physical changes due to the hard work. OFC when they hit 30 they almost looked like 50 yo's from today.
I always laugh at some old soccer trading cards from the 80's where tons of players being at 19 look like men in their 40's. Yes, tons of them smoked like chimeneys and drank like pirates.
