I would object, obviously. It would be murder of a human. You have duplicated me; that doesn't give you the right to kill one of me. The original remains sentient, and I would quite possibly care for it more than I would care for other family. Analogy: impregnating a woman and (eventually) causing her to give birth - that is, "duplicating" her, although the copy is actually not very like her - doesn't give you the right to kill her. I'm fine with teleportation, if that's what you mean, but I go into that with the intention of the death of one of the copies. It's effective suicide, not externally-imposed murder.
