Indirectly Itachi still...

[USSJ Future Trunks]

by that logic hasnt obito INDIRECTLY saved the world by uniting them together into one alliance?
didnt sakura INDIRECTLY save the world by saving naruto in the beginning of part 2?
didnt rikudo sennin INDIRECTLY cause every single bad event to happen and is thus the worst villain?

he does plays out on more than one level. Itachi is the NV god.
Itachi is like Aizen from Bleach: Back up plans for back up plans and stuff

itachi is like renji from bleach. arrogant cocky and stupid. his supposed "plans" were vague and repeatedly failed
