Is it possible that an edo can be killed by AMA ? I'm talking about an edo with no way to escape it like shinra tensei . What would really have happened to Nagato if he didn't shinra it off . Why would he even need to shinra it off if he knew he was an edo ? Does this mean that the
Black flames will eventually somehow burn forever and kill the edo ? Or does this mean that they would simply be in an infinite burn and an infinite healin process ?
