Proof? I only came with theories.
If you bothered to read u could see that the name was only a little part of the assumptions.
I know fully well that Obito was not abondoned and that he was a good guy. I have all the books so I have read it quite a lot. Do u really mean someone who is nice can't get evil? What about Sasuke?
This is a manga series not a reality, so anything can happen.
The last you said I can't answer. It is a loop hole indeed but not something Kishi couldn't have explained.
It would be nice if you also commented the other theories and not only the one u find loopholes in!
And please quit the though tone. Bashing someone because you can't understand or don't believe in their theories, only make u seem immature.
I still like the Deidara "hmmm?" you are writing after a question.
