No, I phrased myself incorrectly.

It would be ethically debatable to resurrect a species so closely related to us not having grown up and fitting within the modern environment and world. Their immune systems aren't built for it. What I alluded to with my comment is the fact that as the species responsible for their extinction it would put us above them in a social order, in which regard the question is why we would resurrect them, because of the problematic relationship this gives us to them while we are keeping our own ethics in mind.

Think of the analogy of how people from African countries like Congo were kept in "watch zoos" in countries like Belgium in the 20th century, in which case we are dealing with the same species as they were homo sapiens, but treated in an inhuman way in a system in which one group of humans dominated another in an unjust way. It creates ethical concerns to resurrect a species like Neanderthals because we wouldn't get similar situations where a dominant group like us starts to dominate them, and governments with a proper law system might not do this, but this would be so tricky that they will have serious ethical concerns on this.
