Is it "good" to have altruistic, moral compulsions?
In terms of an evolutionarily successful development, apparently yes. Despite any cold, pragmatic biological reasons for their presence, we can only experience altruistic "compulsions" as feelings, ie, emotionally. If we are sensible about it, we will suspend our knowledge of the origins of the feelings and go with our emotional motivation and consider it a good thing.
Is it "bad" instead to...say, practice "survival of the fittest"
We don't practice "survival of the fittest" we are a product of it.
and let the weak and elderly die?
I only have personal experience of the case in my own country where there is a national health service which allocates considerable resources at great financial expense to keeping the weak and old breathing. As far as I'm aware, the NHS is not a religious institution.
And how do we know which of these is genuinely "Darwinian" and "adaptive"?
Does it matter?
Darwin plugged more for the latter than the former, it seems to me.
Natural selection is what it is, regardless of what Darwin "plugged for".
But even if we claim altruism is "good," how do we know that?
Because, hopefully most of us, find it emotionally satisfying.
Absent a meta-scheme of morality that covers both and tells us what he moral value of each of the two alternatives is, which one is "good" and which is "bad"?
I don't know what you mean by this. Perhaps if you rephrase it,
absenting any attempt to sound clever and paying more attention to your spelling, I would be more able to give you an answer.
