Determinism

Not about should, about what one wants / intends to do.

will - intend, desire, or wish (something) to happen.

The jury’s out on whether it’s mistaken.

Not only is our will determined,
we have no real agency.
We contribute to the result,
only as much as one domino pushes another,
as it likewise itself was pushed - no meaningful agency.

I’ve yet to see any convincing argument as to how one’s will can be said to be within one’s (meaningful) control - at all.
i.e. that we have any freedom to direct it other than it was determined to unfold due to the chain of causality.
