There is absolutely nothing to conclude that Richard was thought “evil” in his time because he may or may not have had a raised shoulder - this is a cliché about a time that was really much more sophisticated than commonly thought. In fact, the brilliance of the nobility and royalty is quite remarkable. The more I read about them the more I’m impressed with their genius.
There are no contemporary accounts of Richard being deformed. In fact, the reconstruction of his face shows a quite comely individual. His physique is considered gracile. He was small and fine boned. He was a fierce warrior who preferred a battle ax to any other weapon. He was also a fine horseman.
Hey, I’m not going to wade into the “Richard was painted a villain by history” thing. People feel too strongly about it.
What I said was that he had a severe scoliosis, and that such things were very difficult to hide, with the level of court intrigue. It was a vicious time and at that level real schemers use everything they can to do all the damage they can - and no one will say the Tudors weren’t schemers. Heck, they killed him, didn’t they? Now what people thought of him at the time we’ll probably really never know.
