The ethics of respecting someone's final wishes

Your closest friend has recently passed away after a long illness. She was a prolific writer throughout her lifetime, but she never sought to have her work published and had supported herself by way of paid employment. Your friend had never allowed you or any of her other acquaintances to read her work.

Before her death your friend made it very clear to you that she wished you to destroy all of her writing.

However, as you are clearing out her possessions you start to read the various manuscripts piled up around her home. You realise that your friend was actually an incredibly talented writer.

As someone who has worked in publishing for many years, you feel that her works may have the potential to be regarded as important works of literature for generations to come.
