I've actually read this fairytale that shows the wolf in a more positive light. I'm telling you this because the description says that I should.
It's this Native American fairytale about a little girl who comes home from eel fishing with this big sack full of eels she caught and this starving wolf notices the sack of eels and follows her and tries to get her to feed him one. He tries howling to get the moon to show behind the clouds once they move away in the sky and the little girl explains that the moon always shows at night when the clouds clear up. However, she takes pity on him and feeds him an eel regardless. She decides to talk to the wolf on her way back home. Of course she is pretty close to home at this point and someone in her family (I believe her grandmother) notices she's home and asks her if the wolf tricked her out of one of her eels. The little girl instead tells her that the wolf just protected her and they reward him by feeding him another eel. The tale ends with the wolf falling asleep next to their shelter.
Aside from that story, there is a children's book called The True Story of the Three Little Pigs which theorizes that the "big bad wolf" as people call him came to their houses for a cup of sugar he needed to bake a cake for someone in his own family and that he only killed the pigs by accident when he sneezed their houses down from a really bad cold he had and ate their corpses so they don't just rot there. It wasn't as good as the last story, but the wolf wasn't evil and at least he didn't die.
