Lol. Isai just wants to become Raikage and lead the Republic. That totally isn't world domination or that different than Naruto wanting to be hokage, right? Besides, Isai has zombies. So we should all just let it happen for the sake of Zombie Ninja Apocalypse. :3

The way I've set up my Raikage it wouldn't be out of character to kill him as well as it wouldn't be out of character to just banish him. It was a threat that Atlas's character has to live up on or otherwise he will be considered weak. So since it doesn't break character in both scenario's then there is no point in killing Isai as a character but there is no way that he isn't getting banished if that office isn't clean. I don't understand why he doesn't get one of his Zombies to do it but whatever. I'm sure he can get strong enough as a missing nin provided he keeps training. That is my take on it, if it is in character to kill and or to spare then spare the character because it is just as important as your own.
