What makes 'confidence schemes' ethically problematic for ethically sensitive persons?

Cruelty to persons around the world and throughout natural history is pretty awful.

Aesthetically, that makes ANY kind of metaphysical confidence pretty darn difficult for us mere mortals.

Even if some observable PROGRESS - moral progress, not merely technical improvements in methods and mechanisms - devices and dynamics - could be evident, the needless suffering and victimization make 'lipservice' to prior conceptualizations seem pretty unethical to sensitive folks like us.

But then, who really knows?

LOVE CHANGES EVERYTHING

Love, love changes everything
Hands and faces, earth and sky
Love, love changes everything
How you live and how you die
Love, can make the summer fly
Or a night seem like a lifetime
Yes love, love changes everything
Now I tremble at your name
Nothing in the world will ever be the same

Love, love changes everything
Days are longer, words mean more
Love, love changes everything
Pain is deeper than before
Love will turn your world around
And that world will last forever
Yes love, love changes everything
Brings you glory, brings you shame
Nothing in the world will ever be the same

Off into the world we go
Planning futures, shaping years
Love (comes in) and suddenly all our wisdom disappears
Love makes fools of everyone
All the rules we made are broken
Yes love, love changes everyone
Live or perish in its flame
Love will never never let you be the same
Love will never never let you be the same
