Uh, no, not at all. There is a difference between what Danzou is and a terrorist who believes he is fighting a holy war. You are way off there.
Not really. I just used Osama bin Laden as an example of that type evil leadership. Stalin was the same type leader, just using a non religious ruthless ideology- a ruthless ideology is a ruthless ideology. I only used Osama bin Laden as my example rather than Stalin because Stalin's been dead for a number years and even to my generation was kind of a vague historical figure. But if it makes the comparison I'm making clearer, without muddying the image with religious contexts, Stalin makes a good comparison. I'm not talking about the totally crazy evil type dictators like Pol Pot or Idi Amin- the monstrously evil leaders that were the center of news coverage when I was growing up- but a leader true to a ruthless ideology capable of swaying a population to enthusiastically follow that ideology. It's a much scarier evil because of that- it's not so crazy that most people outright reject it, but sways many to follow it. But those that vocally reject that ideology are eliminated in the same ruthless way that Pol Pot or Idi Amin used on the entire population of their countries, scaring others that disagree with the ruthless ideology into silence. This is what Stalin did in the Soviet Union. Danzo has done something as ruthless with Root members with that curse seal on their tongues and making them believe they must have no emotions, no bonds with others. (Note as well how Danzo looks suspiciously at Sai when he only asks a question of him- definitely makes me think of some of the stories I heard about Stalin.)
Hashirama was a generation older than Danzo, Koharu and Homura. Also look back to the founder of the ninjas, the beliefs that Hashirama passed down were quite close to his. What Kishimoto has set up is two competing ways, the way of the Rikudou Sennin which the Senju clan tried to follow, and that of the Uchiha which is of the same ruthless ideology that Danzo follows (I still wonder if Danzo wasn't Madara's student since they use much the same tactics) so Hashirama's way is actually more "old school" than Madara's or Danzo's. Hiruzen improved on Hashirama and Tobirama's way, and Tsunade improved on Hiruzen's, each step bringing them closer to the Rikudou Sennin's ideal. But yes, we've heard from Jiraiya, Nagato and Minato that the ninja system itself has to end for real peace to happen, and we know Naruto will be the one who does this.
I believe I understand your conclusions though, and you make good points- shows me where I need to try to clarify my points. I'm not that great at debating like you are.

Have you had classes on how to debate? I didn't because I have a strong personal dislike for conflict- I became a fan of John Lennon and Yoko Ono when I was 12 because they shared my dreams and ideals, and consider them my mentors. I'm passionate in my beliefs like they were/are, but like them I ultimately believe conflict is pointless. (so of course I totally love this concept is playing a strong role in part 2 of the manga.)
I definitely did like your strong stand against Sasuke being with anyone because of the type person he is- even before this latest chapter sent shockwaves through the fandom. I wasn't quite as strong on that point, but when you posted, it made me wonder silently if Kishimoto wasn't going to make sasukarin a plotline about how it's not a good thing for a girl stay with a destructive minded guy, even if he does have some small attraction to her. This chapter seems to answer that question. I wonder if he'll have Karin make a break with Sasuke- if she is still alive, or will he continue the pattern like it sadly happens all too often in real life, and she'll stay with him because she's in love with him. Will she break free or will she become a tragic figure that truly dooms herself? What do you think?
