Zeneta, Did you watch the doc? I find that many are still in denial on this subject. You seem to be one. No one is saying all are involved. It is human nature to be good.
Actually, no. The entire Western Civ understanding is that all are born in sin and that the world is a fallen place, in need of a Savior. No one can live a sinless life, hard as they may try. Our Founders recognized this reality and it informed their construction of "checks and balances" in our government, because no one group with power could be trusted to operate according to purpose without others exerting a check on power. And that's also why there are three branches, not two; so there would always be a tiebreaker.
