strange twist comming up: Madara will be responsible for bringing peace to the world
I know this title sounds strange (and it ended to be a long tekst to )but just bear with me for a moment.
this story is all about breaking the cicle of hate, now in a normal shinobi war there are 2 or more sides with shinobi from the villages and country's involved. they all have their names, history's and reasons for fighting. in turn this means that when a shinobi kills another shinobi then the people that loved him will most likly (according to the cicle of hate) start hating that shinobi and want to take revenge. at the end of a normal war people are left in suffering on both sides, and on both sides there are survivors that start hating the other side for the murders that happend.
now to show why it's different from this war that madara started. and a quick look at madara's army should make it clear. it consits of plant clones made by zetsu and was added by dead shinobi from the past by kabuto. so basicly this is a 3 man army. madara, zetsu and kabuto are facing the world. and madara alwais intended it this way (at least himself and zetsu, he got lucky with kabuto joining him, for now)
now it might not have been his intention but this means that the focus of all the hatred that comes from the result of this war will be directed to madara, zetsu and kabuto. lets have a look at these three:
1) we know madara is ancient and has no family anymore, also he is seen as a major criminal, no one in his own village still cares for him. there is no one to hate the killer if madara gets killed
2) zetsu is a plant, we don't know his origins but I suspect that he aswel is an ancient person that managed to survive thanks to madara and the experiments with the firsts cells. I belive that madara actualy made zetsu by transforming one of his allies with the firsts cells. if this is so then zetsu also has no one who cares for him. he is big in numbers but weak, so I suspect he is going to be killed also. and with no one to care for him the hate also ends there.
3) last one, kabuto. kabuto's origins are also unknown, he was addopted into the leaf but deflected, he has become a major criminal and now by resurecting dead shinobi for the war has also attracted hatred from the shinobi world for discrasing the dead. he only had orochimaru as someone who might have cared for him, this is unsure since both oro and kabuto have always hidden their true feelings. so with kabuto dead that's also a cirlce of hate that comes to a conclusion.
since the army is built up of these three people with this kind of background, if they get defeated that will be the end of the hatred. so as I said, madara never intended to attain peace in this way (he wants to use his moon eye plan) but his actions caused the shinobi world to unite and focus their hatred on his 3 man army. with that small army defeated it's the end of hatred and a united shinobi world is what remains, all focusing on the hero that defeated madara.
yes, I know I didn't include sasuke, but we didn't see him partake in this war yet. even if he does the hate that comes from his death will end, since it's the people that care for him that will take him down.
