Political Correctness Again

This is Agatha Christie's top selling book, about ten people trapped on an island and condemned by a killer who executes them one by one.

It was published in the UK in 1939, but released in the US as Ten Little Indians. Even though this is from a nursery rhyme, even that was considered potentially offensive and changed to And Then There Were None the last line of the rhyme.

The rhyme, though, was still retained inside the book referring to Indians.

Now the question is: did the original composer of the rhyme come up with it out of meanness in the first place, black boys all dying one by one until they are all eradicated?
