Hehe. These are tough questions. I had a specific scope in mind. But to answer your questions.
> Is 'good for the social structure' the metric to use for defining good?
No.
> Should we be serving the social structure to be 'good'?
Yes.
Does that make sense? :-)
It makes sense.
But, imagine the case where I do not think serving the social structure is good. And I make what sound like cynical jokes about serving the social structure. For those that believe in serving the social structure, that cynicism only had negative connotations. But for those who don't believe all that, the bitter joke might accurately reflect their understanding according to reality.
