The lamb spends all its time worrying about the wolf and ends up being eaten by the shepherd.— Unknown
I think one could look at this from several perspectives or through different lenses.
We worry about the wrong things.
At some level, this is about trust.
We trust the wrong people. Those whom we most entrust do us in. But I feel this is contextual.
One might feel this shepherd is Capitalism or the State or organised religion. Perhaps it’s culture or identity cohorts. Or all or these or none of these.
On another level, it recalls the inevitability of death. This shepherd reaper is always waiting in the wings whether or not one worries.
In the words of RATM, Know Your Enemy.
