War has nothing to do with it.You don't understand war.
Obito Grew up in a time of war, So did kakashi, So did Itachi and many more. Obito should stop acting like a Brat and understand life is full of heartache and pain, Deal with it and move on
Itachis life is Far far far worse than Obito's, And he still loved his village and died a hero Twice.
