In the Narutoverse who is the most tragic Ninja story?

Itachi Uchiha

"he accepted disgrace in the place of honour...& hatred in place of love....and yet itachi still died with a smile on his face...."

I guess it would be Nagato. I mean where he grew up and losing his parents at a young age, and also losing his best friend.

i think itachi cause itachi sacrifices his own clan and his pride for saving his brother and most importantly the village and he should be considered the true hero he accepted hate in place of love and this is what it makes his story tragic

(Almost) everyone had a tragic childhood, but to me, none come close to Gaara's suffering.
It was just... so messed up beyond words. Being all alone and hated by everyone, living in fear of being assassinated any moment (though no one could even touch him cause he's so awesome >.>), and being betrayed by the only person he thought cared for him. And then having a hateful demon torture his mind every single day. That is one extremely screwed up childhood. ;-; I don't blame him AT ALL for turning psycho. V_V
I'm just.. so glad he finally found happiness now~ :')

Itachi would be 2nd on my list.
