Not really. Ransomware works by creating an encrypted copy of your data and then deleting the original data. The direct harm comes from deleting the original. Where would the harm be if all they did was create an encrypted copy without deleting the original?
And the same attack works if instead of encrypting your data they upload a copy of it to their servers before deleting it. Albeit less efficiently, so we're back to indirect harms.
