@Zetarion; if you don't want any part of this, just go away.

@Damon; no they are not, this chapter proved that so, the fact that Natsu is not dead proves that much, Zeref said that if he dies, then Natsu dies too, there is no other way around it. No one said anything about turning evil, but still END representing Killing Instinct is a personality of itself, does not mean they are the same mind, just sharing the same body. No, Natsu was enraged that led to END surfacing, it is not because of Zeref confusing his mind, there was no hint of that at the moment.

He was brought back by the Demon's Power and was given Dragon's power, that is how this works and worded.
