I think this is an excellent question, but it's one of those that tends to ignite people's passions. For me, the question boils down to a legal issue more than anything else. Under the law, if you wrong someone, you are liable for damages.
Imagine that I take a whip to my next-door neighbor, tell him he's my slave, hold him hostage in my house and make him do a bunch of chores. A week later he escapes and calls the cops. I'm going to find myself in all kinds of hot water and liable for all kinds of damages (battery, false imprisonment, etc.). If my neighbor keels over and dies before he can collect the judgment, it will go to his heirs.
In short, I believe a legal wrong has been committed. There have been tearful apologies, but I don't think you get out of compensating people for that wrong just because doing so - i.e, figuring out who should get what - might be difficult. Doing the right thing is rarely ever easy, but you're either committed to doing it or not. And when we start saying it's too much trouble to do the right thing, then we're really in trouble.
As the old saying goes, "All that's necessary for evil to triumph, is for good men to do nothing."
