Madara, Sasuke, or Obito?
Madara- lost Izuna & hope for reality
Sasuke- lost itachi & parents
Obito- lost Rin, Uchiha clan
, Deidara & hope for reality
Obito = He never have a chance for getting a happiness in his whole life after being save from the boulder incident event.
But glad finally he really getting what he want although it actually in afterlife not a living world.
It quite sad
Sasuke is not so sad because the incident he is trough is involving his own brother
Even in one point he had a hatred toward his own brother.
And want to kill him
And it did, although Itachi actually wanted to ending his life from his own younger brother hand.
But not much emotion of sadness I can feel toward him, even he don't look sad at all.
He just full of himself
How I'm able to feel his feeling
Peace
