Hi TNX
Whilst I may not have answerd your question it is important to note that on numerouse occassions in the watchtower literature you quoted it was stated Adam was created perfect.
The scriptures you quoted to prove Adam was created perfect was based on Watchtowe interpretation. The watchtower could change their interpretation tommorrow and as Witnesses we would accept it.
We belived Jehover would bring the Wicked system to an end before the generation of 1914 passed away. We belived Jehover promised it and we backed up our beliefs from scripture. But Jehover didnt promise it and the Bible made no such statement. YOU quoted Deuteronomy to me. Could I suggest you read Deuteronomy 18v20-
I mention these points because if you wish to have your answer answerd to your satisfaction from the Bible, then you need to realise that the Bible does not always say what religiouse organisations claim it says.
