Maybe a bit harsh. But I have to agree. The only person on the show that is shown to be immortal is Rumple, and even he acknowledges his mortality (he can be killed with the Dagger, and as we saw, he can eventually succomb to the darkness that builds up inside).

However, in saying that, what we are seeing in Emma's vision is not the normal ending of life, but events that lead to a premature termination. (that's assuming that her vision actually ends in her death, something that I am still not 100% convinced is fact). It's one thing to die of natural causes (something that we have really not seen on this show). It's something totally different when an outside agent intervenes to cause the death of someone. And that is the type of vision that we are seeing, which is introducing some (trumped-up) tension into the story. It does, however, raise the question of whether Emma will be able to prevent the circumstances of her pre-mature death so that she is able to survive until her natural death.
