The main goal is to increase diversity. The one thing that is bad for society is low diversity. This is true for culture or evolution, for species and also for whole societies. If you become a monoculture, you are at great risk of perishing.
I have faith that science is a good thing. Seriously, I'd say that I am very much in awe of nature. In fact, I think to some extent, "awe" was a word that was almost invented for scientists.
This is a whole new era where we're moving beyond little edits on single genes to being able to write whatever we want throughout the genome. The goal is to be able to change it as radically as our understanding permits.
A poet sees a flower and can go on and on about how beautiful the colors are. But what the poet doesn't see is the xylem and the phloem and the pollen and the thousands of generations of breeding and the billions of years before that. All of that is only available to the scientists.
Faith is a very powerful force in the history of humanity. So I greatly respect different kinds of faith. Just as I think diversity is a really good thing genetically, it's also a good thing societally.
The recreation of Neanderthals would be mainly a question of societal risk avoidance.
Neanderthals might think differently than we do. We know that they had a larger cranial size. They could even be more intelligent than us. When the time comes to deal with an epidemic or getting off the planet or whatever, it's conceivable that their way of thinking could be beneficial.
