This is reflected both in her not understanding why she would ever do what she did when you first give her the Endsinger-less and Meteion's report-less understanding of the future scenario, and the fact that whatever the "new life" was, Hydaelyn also chopped it up and effectively killed it all in the Sundering along with the Ancients.
For Venat herself, just like Athena (at least, the argument Athena put forth), the primary concern was indeed for her concept of "the greater good," and all forms of life around her were an acceptable sacrifice towards a future that would shape it.
