I looked at Quinn's essay on 'Dangers of Compassion'.Morality is a subjective value and evaluation. It is that idea of how a consciousness affects another consciousness. Since all individual consciousnessses (which is the only form there is and probably only can be) is restricted from any absolute truth or single, final truth, all valuation and evaluation depends on the consciousness in question and it's subjective perception and assessment of itself and others (other conscious beings specifically).
I'm not sure if there is any conclusion to it. The ideal morality is fiction of the mind, perhaps possible, at least we try and most people claim we have made progress over the centuries and millennia. Any circumstance is uncertain, but in the face of this we must act and decide on possibilities.
What opens up is a possibility for non-referential compassion.
a nondual compassion.
a dual-mind compassion is a compassion with reference to a particular or particular sentient beings because the catch is an 'I' feeling compassion towards other as object of compassion who is perceived to be suffering.
a subject/object framework.
inside that frame untold difficulties are set in train.
a non referential compassion is compassion for all phenomena,
nondiscriminatory, unconditional.
