I agree with your analogy, and it indicates the right thing to do here. Give the refund and ask people to delete the ebook themselves.
The doctor wouldn't break into your house and take the pills out of the medicine cabinet.

Perhaps I don't have the same feelings regarding owning a copy of somebody else's work. I don't feel ownership towards ebooks. I feel ownership towards the money I spend, but if I get that back I wouldn't be mad at what Amazon did. That's a minority opinion, and I think it would be worth debating somewhere that's not here.
This of course implies that the doctor would be within his rights if he caused no disorder. "I wouldn't trust a doctor to...". You didn't trust Amazon to either -- they just went in and did it, at someone's request.
Hmm.. why does this prescription bottle have an antenna on it...
