well...it's a powerful tech, isn't it?
In the hands of a hokage it could come in real
handy. In times when the village is threatened by
a powerful enemy the hokage could use to summon a
dead more powerful hokage to help. It will
all be in the interest of the village.
For me the morally 'evil' aspect of
the Edo tensei is not the reviving of the dead but
the high price of human sacrifice it demands.
don't see it as a reason for him to create
the Edo Tensei...there must be some tragedy that
drive the 2nd Hokage to create the Edo Tensei...is
it been told in the manga?...maybe,I'm not
pay much attention...
he probably made it before the creation of the
village. back when they where contantly fighting.
the 2nd made alot of jutsu made the basis for the
4ths tech also. he was probably trying to compete
with his brother since he didnt have wood
possible though...but,why Edo Tensei?...it's
sounds fishy to me...you know,there must be
something that Tobirama wanted to do by using Edo
Tensei jutsu...it sounds something big to me...let
ask 1 more time,is it been told in the manga
already,why Tobirama create ET?...
