Actually, observationally I believe my definition of principle to be far more accurate. People self-report principles as being far more immutable than they behave like.

I have not yet met someone who rigidly adheres to theirs. Perhaps if I had met the Dalai Lama but nearly everyone else will find that the moral space is so fraught that they cannot adequately compress it into immutable laws.

Usually, should one demand such adherence one would find one met with accusations of “looking at the world in black and white” and “lacking nuance”.

Of course I don’t really intend to change your mind, but I do intend to transmit what I have observed.
