Hi doma,
Darwin contemplated cooperation and selfishness. Really he did. And this is a major theme of the folks who represent him now.
Survival is borne not of selfishness but of whatever works best. eg Bees cooperate.
You are not so far from the mainstream in this regard.
I should also note that your idea conforms with my competing forces principle. Except that I don't assign a moral element as you do.
For me, individualism isn't bad and cooperation isn't good. They are forces which describe our existence. They exert a negative influence only as they exclude one another.
