Selfish. In a word she is selfish
But...but...she values “intellect, precision, hardiness...and most of all...’planetary repair’.
Everyone is. Some are worse than others.
The people who have kids because they want them, and the people who decide not to have kids, are both doing so because of selfish reasons. Both do what they want to do.
Everyone does what they do or dont do out of motivated self interest.
