Itachi had absolutely no justification for killing every single member of the clan.
I alrady gave you plenty of it.
He could have simply done what he did to Sasuke on the rest of them, let them focus their hate on him.
Right, because it would be believable that he allowed them all to live to "test his power"? Because Danzo did not give him the ultimatum on who to kill? Because Danzo did not already told Itachi what the deal is to keep Sasuke alive? Because Danzo and the elders would allow them to live when it took so much to allow even Sasuke to live (aside for the deal Itachi also had to threaten Danzo and beg Sarutobi to protect him).
Not all members of the Uchiha clan were in on the coup, surely the children and those without the sharingan were not going to participate in anything.
Sasuke was not in it as he was to young. Anybody old enough, sharingan or not would be in it.
We don't even know how many and if any children Sasuke's age were around.
Tell me, how many kids did the story implied were around? How many were showed? I know it would be freaky to be the only Uchiha at that age but who knows.
You say that those children and women would have been killed anyway... No, they would have been murdered anyway by Danzou and co. You cannot indiscriminately wipe out an entire community of people and justify it as doing it for the greater good by murdering potential enemies. It is absurd.
Murdered, killed or whatever you want to call it. Point is they would be put down and if Itachi did not follow his order not even Sasuke would be left alive. How good this system is... Well its besides the point, we are arguing Itachi's fault in it.
Now I do not agree to genocide and I would not do what he did. Point is he saved so much people its incalculable by his actions. Kill 10 kids that were going to die anyway to save hundreds or thousands from death, starvation and so on? You know Nagato's story right? That is what he saved, those type of kids growing up with no parents or flat out die.
I am telling you that murder IS SUBJECTIVE. Murder is applied in the context of the rules set by the government and the society one lives in. You applying your laws and your moral to this is not right. This village is set something like feudal Japan.
Now read here who even Hashirama would not forgive:

The children where a future danger to the village, perfect example is Sasuke once he found out the truth. I am sure Hashirama would not kill the kids but someone like Danzo and the elders will. Also take note its not those who harmed, who would try to harm, even the attempt is sufficient.
To the Naruto world Itachi was not a murderer, he was a hero that saved Konoha and stopped a world war before it even started.
Stop throwing around the definition of the word murder, everyone knows the difference. You are the one who refuses to consider or even acknowledge the existence of innocent civilians within the Uchiha clan. Again, Itachi may have killed those involved in the coup or those planning it but he murdered the rest. Even what the elders would have done was going to be murder.
I am the only one who looks at this with no bias. You people are not. Did the Uchiha clan consider the innocent civilians that would die by the thousands because they would attack Konoha when they refused all the attempts Sarutobi made for peace? The same village they swore to protect.
The genocide happened when diplomacy failed and they about to attack. What was left was a civil war, world war or wiping out the Uchiha. The choice was made for the lesser evil. A village needs to protect itself.
Its obvious you have never been in a position of power and its a good thing. If you have 3 civilians under you who would kill 1000 if you do not kill them and you do not kill them... Well you are a horrible leader. Those leader need to consider the majority, they need to consider the safety of the village as a hole. Its easy to scream murderer when you do not need to take this actions OR have to sacrifice everything like Itachi did. Yes, I would not be a good leader just as well since I would not sacrifice those people to, think is sometimes thinks can be justifiable when you save lives by taking out the dangerous element.
And wait, are you seriously trying to differentiate between Tobi and Obito as if they are two completely different people? No. Obito was not suffering from MPD... He did not have an alter ego. He made those decisions and even acknowledged doing them. Obito suffered a psychotic episode when he saw Kakashi kill Rin. After that, he made conscious decisions and was aware of what he was doing, who he was and where he was headed. He saw loss and chose to turn that loss into something dark and twisted.
If you did not get what I meant by Obito and Tobi... Tobi was the one who was full of hate the other one full of love who helped people. Think of Vader from SW. After Naruto saved Obito from himself and got him back to the one ready to sacrifice everything for the village he acknowledge him as "the coolest guy" since Naruto and Obito share the same principals and ideals at that point. That is who Obito really was before Madara's manipulation. You really have no clue what manipulation on that level can do to a person at the age Obito was.
