This is coming slow because I'm having to think about it. I can only approach this on another tack (sailing again Praise).
In some sense the human condition may be brought about by the smallest preferntial desire to teke care of one's own children before others. There is a selfishness to all of us but (to my mind) it is not necessarily born from the "enemy of evil" but can be generated by preferential love. I'm not trying to raise flames here but to go very gently. It is natural for a parent to want the best for their children, and the result of children that grow up lacking this love are clearly evident everwhere, but this very gentle preferential pressure becomes the syndrome known, I suspect, as the selfish gene or the original sin. Once selfishness in some degree is accepted as natural then the offspring is something of the problem to which you refer.
I can't for the moment put any more of this down, but we are all human, it's not a perfect world, and sometimes the listening stick will be required. To be honest may require that we forgive ourselves more freely than we have been used to for a failing that was never a failing but something that was thrust upon us for survival.
