I also like Oscar Wilde’s The Happy Prince, which has a good moral to it yet doesn’t preach. You draw the conclusions yourself (which is always a sign of a well crafted story).
When I was in the mood for gruesome justice being doled out to those deserving it, The Three Little Pigs as originally written was the story for me.
The great thing about writing is you should read as well to help feed that writing. And in what other activity would you scrutinize a character and understand how they “tick” before go on to write your own?
So write away, analyse the characters you love reading about and hopefully create yours knowing your love of reading is the answer.
