Well, I don't want to make out anyone was trying to really stop her, or not that I recall. It wasn't a big moral stance, there was just no reason they really needed to die.
But you're not at all wrong that she's always been a better person by far than she's in the habit of understanding herself to be, and it has been something of a project of mine in the decade or so since her retirement to amend this regrettable flaw in her normally incisive perception, as and when I'm able. So thank you, in advance on her behalf and right now on mine, for the compliment! I confide she'll appreciate it, when I pass it on in our next talk. (I'm also looking forward to her take on the article, if indeed I decide on reading it that it suffices to merit her attention. Neither she nor I appreciates having her time wasted, after all.)
