Look, Nobody understands the pain Itachi has went through. I can sympathize with him... You have to realize that Itachi has done all of this for the good of Konoha.... Here's the thing, I get it, ok? It may seem like Itachi was a bad guy, but I would probably do the same thing if I was him. I'd be able to handle it, because Itachi has sacrificed so much for our industry...
He's bottled up all of his feelings, and the fact he hates war is a reason why he chose to destroy his clan and become a villian. He's seen it all, and done it all in this business. You know I heard a saying when I was a kid..:
"A wise man once said, words are nothing more than empty expressions, floating, in a sea of deeper meanings"
and I didn't understand what it meant at the time, but now I do. It means we can't always see what is in front of us, we have to see the bigger picture. Itachi has been through so much, He's definately a future Naruto hall of famer, for sure.
