I'd prefer useful, peaceful coexistence, but that almost never seems to happen.
Observe the microcosm of human interaction right here: it's almost entirely about unnecessary conflict for the sole purpose of displaying the appearance of intelligence. Those who do it, see it everywhere, whether or not it exists.
In the real desert-island, scenario, the crow would share what it knows, for no other reason than that it knows it. It wouldn't do that if it wished death for the others. Nor if what it wanted was distance. After all, it has wings.
But crows - real crows - are the most misunderstood of creatures. Closely followed by raccoons and foxes.
Yet those creatures have no use at all for humans, other than to scavenge from the mountains of useable waste that humans produce. Humans would much rather their waste remained waste, than allow other creatures to make use of it.
Scavengers! They cry. As if that were some terrible thing.
While they scavenge among the accumulated wealth of preceding generations, putting nothing back while removing all they can.
Humans will vanish, by and by, while crows, raccoons and foxes continue to do what they have always done:
Making a modest living from the bounty of nature, neither adding to it, nor harming it.
And intellect be damned.
