Richard is a bit maligned though no doubt a bad man
And likely did have his dear nephews killed in the Tower
And not his only crimes
I believe he was not actually a hunchback but suffered from scoliosis
Surprised AP would not distinguish

There is a defend Richard culture in the UK to refute some of Shakespeare’s descriptions and charges that were embellishment
Of course, if Henry VII had killed them, it would have been very unwise indeed for Shakespeare to write a play about Henry VII's murder of the princes, even if he had known it to be true.
Elizabeth I would have had Shakespeare rendered to Richard Topcliffe to have his gonads removed.
IIRC Shakespeare based his play on the official Tudor version of history. This incorporated Bishop Morton's vicious polemic against the dead Richard III. We can't treat Shakespeare's play as impartial evidence.
There is no evidence Richard killed his nephews. They did disappear from sight under his rule. Some people think they were escaped to Europe. Check out the Perkin Warbeck story. The children were declared illegitimate after it became clear that their father was a bigamist. No way would Richard (as protector of the realm) have allowed a “bastard” to assume the throne. That’s just the way medieval royal minds worked.
Richard instituted bail into England so that commoners would not lose their homes and farms while under arrest (usually arrested by corrupt nobles, btw). He was an outstanding soldier, well-liked by his troops, who stampeded Henry VII at Bosworth while that gentlemen hid behind a tree.
He deeply mourned the loss of his young boy and wife.
He had scoliosis - curvature of the spine; no hunchback. No withered arm, either.
Thomas More made all this stuff up because he grew up in the house of Thomas Morton - Richard’s mortal enemy.
