A brain dump has a history, and we ascribe meaning to the past. As mentioned the thread here has mentioned forced prison labor as a form of socially acceptable slavery, and society could convince itself that a given brain dump deserves its fate, even that it is a form of atonement.

Artifical life on the other hand is presumably "pure at birth".

Of course it's not that easy. You could discuss whether individual instances have unique sets of human rights, and value potential futures over pasts.
