“At least one out of the three will gladly and willingly trade herself for security.”
I detect a certain judgmentalism about that hypothetical “one out of three.”
That survival strategy is the natural order of things throughout the animal kingdom, and throughout the history of humans, who are a subset of that kingdom.
If the other two do not follow that strategy when society breaks down, whether gladly and willingly or not, they will not contribute to the gene pool, and their contribution to the biosphere, except as nutrients to be recycled, will terminate as well.
I would not judge them.
My comment was somewhat tongue-in-cheek because the pictures are animations of the same girl.
As far as the gene pool is concerned .... welll ... MY father told us (6) boys, "A stiff dick has no conscience" .
You learn all that societal stuff waaayyy later in life ... after kids have been born and etc.
