If killing women and children is a sense of Justice then fuk the so call Will Of Fire.Fancy answer: They're cursed, that's why. Though, Itachi and Shisui each broke their curse with their overwhelming will and sense of justice.
Real answer: Idk, Kishi just made em that way.
Pure Uchiha as to what?....Itachi is no boss his a little punk who killed his own mother and that makes him lower than anything while Sasuke on the other hand is a true boss who will never attack his own mother and raped Danzo now that's a boss.Itachi is the only pure Uchiha, he's was a true boss. I think he's even more boss than Madara.
*sighs* Here we go again.....If killing women and children is a sense of Justice then fuk the so call Will Of Fire.
Where is your proof that Obito killed the Women and Children?*sighs* Here we go again.....
For all we know, Obito helped Itachi is the massacre, so he could've been the one to do the extreme dirty work. Even if Itachi did kill women and children, I'm sure he did it so quickly that they wouldn't have felt pain even for an instant. Itachi saved thousands, maybe millions by killing hundreds.
