Frankenstein’s “Monster” was blind to what would happen if he threw the girl in the pond. It isn’t his fault, but then the villagers went and burned him. What a way to go man, what a way to go - Just being animated in a body that was formed from corpses around the town then being tormented by someone (Fritts) out of no fault of his own (And eventually killing Fritts) and then getting out of the castle, meeting a nice little girl and smiling that she’s so friendly (The only character in the whole movie who was nice to the “Monster”, in fact!) then throwing her in the pond without realizing she wouldn’t float like the flowers, much like a toddler in a 30-year-old-body (or whatever adult age) may do - Then the villagers just went like “BURN YOUR HOUSE DOWN!”
 
Really, OUCH. There’s reason why to not kick a blind man because he is blind, and the villagers were hopefully blind to the fact - or else they were being nasty and the “Monster” is blind and innocent due to not having ability to understand.

You’d want stories that end up well, at least.
 
Given the class sensitivities of the ponies in Canterlot, Jane Austen would probably work for ponification quite well.
 
The lighter Shakespeare. Misdummer Night’s Dream, Tempest.

“The scarlet cutie mark” but still better than the movie XD
