What I found funny was in the end Tobirama was proven right. He was right in a sense to not trust the Uchiha. They were segregated somewhat yes, but they weren't openly ostracized. They weren't slaves or outcasts or exiled by the village. They didn't have the power or say they wanted when it came to village politics and protocols so they to planned a coup. So why am I supposed to feel sorry for them? They were the ones willing to risk civil war just for more power in Konoha. It was that choice that gave Danzo the opening he needed to deal with them. It's one of the few times in this manga you see a choice lead to devastating consequences.
I've always believed that you must take responsibility for your choices and accept the consequences of those choices whether good or bad. While I don't like Itachi's character I never really disliked it either because he was shown to be willing to suffer the consequences of his choices. He chose the safety of his little brother over his entire clan. The safety of Konoha I always felt was secondary. But he was willing to take on the consequences anyhow.
Hiruzen Sarutobi was also shown to be someone who knew that one day he would have to answer for the choices he made, and answer he did. However these seem to be the exceptions to the rule in this manga. Forgiveness and redemption without consequence became the norm. The hokages, the counsel and the village itself became the excuses for Kishi to use to try and pull that ideal off. Once Kishi decided that he was truly going to focus on the redemption of certain characters rather than the change and justice that was supposed to be brought on by others, the story was ruined. So instead of the heroic tale of Naruto Uzumaki, we got the redemptive tale of Sasuke and the Uchiha clan.
You're not supposed to feel sorry for them but you're supposed to understand that konha had a part to blame too
And Tobirama was proven right because of his own actions, his fear and distrust generated anger and hate within the clan
