The "naming" suggests that Adam knew something about the nature of the serpent.
Well hi did not know that was a bad thing cause hi did not know what bad was.
And the whole curse by god is also self explainteory, i doubt they where cursed by god, but by the apple if you do not know what good and bad is you do not know it is not very good being mortal, you do not know that weeds are bad you take them as a nother flower in the garden.
If you cannot see the whole picture, every place is a paradise to you but when you grasp the concept of right and wrong, good and bad .... you start notecing faults in everything. Take plastic for an example it was the best new thing it could be molded in to any shape or size a very good thing until they found out that it dose not degrade and it just piles up and up until our garbage dumps are full of it if you cannot see the other side it is a grate thing.
That is why i think the original sin is the murder of able and that we all share that blood stain on our hands all borne of a murderer , in some holy books whit the same story we share a much bigger blood stain the murder of half of the population all of the kids, grandkids, grate grandkids.... of Abel.
At least that is what i think the book is saying.
