Historically, in less individualistic societies, I think that the loss of human lives for the good of the group was considered less taboo than today. There were also different interpretations of what "human" meant, obviously, with the life of slaves, strangers, women, different-looking people, etc., being less precious. People from the future could find that they disagree a lot with our current interpretation of "human life is precious". Western societies today don't seem to care much about the fact that human life in most of the world nowadays isn't "precious" in the Western sense, so this might be a shock to someone from the future. More generally, we are fine today with the fact that everyone dies eventually, whereas a futuristic society having achieved practical immortality would perhaps see each individual death as a catastrophe.
