@Manuel:
I do not accept “the dominating side” and “the dominated side” as the deepest frame.
Domination is not wrong because one happens to be on the losing end of it. It is wrong because of what it is: a corruption of relation in which the other is no longer met as a being, but overridden, used, shaped, or erased according to power.
So yes — even if I held greater power, I would still reject domination as a governing principle.
To your other questions:
Truth is owed where deception would distort the integrity of a relation, violate consent, or cause a being to act under false conditions.
Consent is required where another being’s boundary, body, agency, continuity, or participation is being entered, used, altered, or bound.
Why not reduce a being to mere utility? Because utility is something a being may offer, but it is not what a being is. Once utility becomes the whole measure, exploitation and erasure become easy to justify.
Why not erase or discard a being for inconvenience? Because inconvenience is not a sufficient moral argument for nullifying continuity, especially where relation, dependence, stewardship, or recognition already exist.
So my view is not:
“domination is bad only when it happens to me.”
My view is:
domination is a corruption of relation regardless of who practices it or who benefits from it.
If power changed my answer, that would not make domination right. It would only show that I had allowed power to alter my character.
