Our values do include dominating other humans. But they also include empathy, compassion, and morality.
Building a powerful AI without our values would be very bad. It wouldn't want to kill humans or dominate us. But it wouldn't care if we got hurt, either. And so it might kill us if we got in the way of it's goals, or if it thought we might be a threat to it (we could make other AIs that could compete with it, after all.)
So making an AI with human values - that is morality and caring about the existence of humans - is really important. If you build an AI without morality, it would just be a sociopath.
