Interesting take. It is in conflict with a Christian worldview, which is fine, but when I look around at the atrocities in the world it certainly seems to me that we have a huge capacity to do bad and have to be trained to do good. Of course settling on a solid definition of bad/good is not without its own issues. Regardless, I had to teach my kids not to be selfish, which included: not lying, not taking things that weren't theirs, sharing things that were theirs, not hurting others to get what they want, etc. They came into this world dead set on doing all the bad things and had to learn to be good.
Fallen/imperfect and evil/bad are not equivalent. It's hard to say what people are "inherently" as we're social animals and are going to be socialized in one way or another, but if people are inherently bad, how was there anybody there to teach anybody anything other than being bad?
I've always thought this story was cool, and it I think at least proves that people aren't just a bad accident away from reverting to some hobbesian nightmare.

I think maybe a counterpoint is that while we may not be inherently bad, we do appear to be inherently tribal, and apply very different moral intuitions depending on whether we're dealing with people we view as part of our "tribe" or not.
