The point is not whether it's okay to look at someone's private documents after they're dead. The point is whether you should honor the wishes of someone you care about who has died, after they've told you their wishes while still alive. Do you have any obligation to your friends or family after they have died, and what does your answer to this say about you? I think it's a different question, and a different answer, and that's the actual case we should be talking about.

Personally, I think only an absolute bastard would agree to what a dying person asked them to do—or not to do, in this case—and then go back on it after they died.
