I disagree with this:
To destroy is human
Every being destroy something when eating, since we are the most complex and intelligent species on Earth, our capacity for destruction is higher, but the same can be said for creation.
I think a better phrase would be "to create is human", thanks to technology. Perhaps in the future we will be able to bring back to live some species that are extinct right now.
I guess Hayden got overwhelmed by the moment and could not come to terms that this sub-species is about to go into extinction. I see your point though. Glad to have you on my wall.
