OK, lets assume that its possible to simulate a human mind well enough that the difference is indistinguishable (this is a very familiar idea in a lot of sci-fi, uploading consciousness and all that sort of thing). If you accept that assumption, things very quickly get complicated. Would it be OK to kill a virtual copy of a person? If so, on what basis? That people running in biological brains are somehow more real than digital ones? Why? How do you know you're not running in a simulation right now, etc etc.
