@Smileyrius,
The text says what it says.
It doesn't say "Because you have done this thing, you are the cursed one out of all of the spiritual beings". It doesn't say, "A spiritual being put words in the mouth of the most cautious of all the animals". It doesn't say anything about a spiritual being putting words in the mouth of anyone.
It could of said any of these things. It didn't.
You have to think about the person who wrote down this story, and the people it was intended for. These people understood this as a story about a serpent who deceived Adam and Eve. They would have understood the story equally well if the story said that a Spritual being deceiving Adam and Eve, after all Genesis talks about God and Angels which they understood perfectly well.
And you keep bringing in John and Revelations, books that were not read by the original readers of Genesis because they would not be written for a thousand years.
The text clearly says it was a snake who deceived Adam and Eve. It goes so far to mention twice that this snake was one of the "Beasts of the Field".
This is how it would have been intended by a writer in the bronze age, and this is how it would have been understood by the people it was written for.
If you don't want to accept the biblical text, then fine. But the rest of this "explanation" is just stuff you are making up with no basis in the text or logic considering how and for whom it was written.
