Whether they're dead or not doesn't matter. The people specifically responsible must pay we can both agree, but what happened at large should be revealed. If Konoha suffers as a result, it'll most likely stop what happened from happening again. I mean come on, Konoha was discriminating against the Uchiha, and when it backfired, they cleaned them off the face of the Earth. What more protection does Konoha need?
Withholding the truth over and over again because you're afraid of the effects will just cause an endless cycle.
Punishing people who aren't responsible for any wrong doings will also cause an endless cycle. For all you know, those innocent people will feel wronged, and then maybe some of them might become rouge ninja out of anger and desperation (due to perhaps losing everything for reasons that they did not bring upon themselves). Next thing you know, they're killing the wrong guy or pissing off the wrong leader. Then 1, 2, 3, bam! We have a 5th great shinobi war! Perhaps we even have another genocide (if that desperate man was apart of some clan whose members backed him up on his stance)!
When it comes to corruption within a government, the proper protocol is to remove those officials from office, not to wreck the whole nation! When Bill Clinton's scandal was found out, what did we in the U.S do? We impeached Bill Clinton! We didn't destroy the whole U.S for it or send negative propaganda about the U.S to other countries, now did we? When Nixon was found to be involved with the water gate scandal, what happened? Nixon was ultimately pressured to resign! We didn't destroy the U.S or ruin our trade relations with China!
In the same way, the proper protocol in dealing with corrupt leaders like Danzou is to get rid of such people, and Sasuke already did just that (only his method was via chidori sharp spear instead of mere impeachment)! The protocol is not to attack Denki, rape Moegi, and crucify Himawari!
Honestly speaking, the details of the Uchiha massacre is nobody else's business at this point. That may sound harsh, but in the end think about this:
What good does it do to hurt babies who know nothing, and to punish everybody except for the actual villains? Furthermore, who actually has time for that now (20+ years after the tragedy)? Like I said before, all of the villages have their own current issues to deal with.
This was your statement:
"I mean come on, Konoha was discriminating against the Uchiha, and when it backfired, they cleaned them off the face of the Earth. What more protection does Konoha need?"
Here is a corrected version of your statement:
I mean come on, Danzou was discriminating against the Uchiha, and when it backfired, he cleaned them off the face of the Earth. What more protection does Danzou need?
Nobody is withholding any truth. Danzou was withholding the truth, but he and all associated people are dead, so now nobody is withholding any truth.
Naruto, Boruto, Sarada, Denki, Iwabe, Sumire, Udon, Moegi, etc... should all just be left out of it.
