So you think if E.N.D. would literally stand for Evil/Etherious Natsu Dragneel is would NOT be stupid?

And if you really think so, why the other argument? You correctly pointed out that the Demons didn't struggle against Alegria, but Natsu did. Wouldn't that be more of a hint that Natsu is not one of them, rather than the opposite?
