I wonder how much this manga's rating would drop if it didn't meet the expectations of people wanting a good MC. If he doesn't kill them, the character development is even worse. He should kill them. Not because it's right of wrong, but because that's how his character has been depicted from the beginning. Else, is it a naruto thing you guys want, a pretty girl says it's wrong then everything someone has gone through gets suddenly erased and guy radically changes his opinion ? Such would be a massive writing hole. Well, writing has been quite garbage in this one anyway, so I don't expect much. Still have no idea where author wants to lead us, characters have zero reasoning behind their actions.
On the other hand, art is fcking amazing. Maybe there's potential in a world exploration.
