Since ethics isn't fixed, then what watermark do you suggest to define a universal ethics. It's like euthanasia, is it ethical for a doctor to commit murder if it's to stop terrible suffering? It was ethical to own slaves, but not ethical to have them work on a Sunday. Nowadays, having staff work Sundays is ethical (although your probably a jerk) though it's no longer ethical for them to be slaves.
