I think your making a distinction without a difference. I've never been in a philosophy class where the efficiency of an action is taken into account, and I don't know what you mean by "valid" if you don't mean efficient, To measure if something is valid you must first set a standard by which it is to be measured. When we are talking about human action, what you are talking about is the morality of an action. Things can be moral, amoral, or immoral. Giving money to a homeless person may be seen as moral, kicking them would be seen as immoral, and happening to sneeze after you pass them would be amoral.
So by what way are you using the world valid? If your talking about logic, then Obito fails on that account as well. His actions aren't logical they are based in a desire for vengeance, his actions are based on emotion not logic.
See this is why I don't know what your talking about. You seem to be using the word valid in a legal sense. In that sense his actions are even less correct. Going from the logical leap from "I'm sad the girl I love was killed by the man I asked to protect her." to "I will take away mankind's free will so nothing bad will happen again" is huge, and I don't think a case can be made that there is a logical set up to that chain of thought, there would be to many fallacies. It's an emotional response not a logical one.
Or are you meaning valid as in it aligns with his character in universe mindset? If that's the case I suppose you could say that since it's stated now that the Uchiha are basically so overly emotional to the point where they are illogical individuals. At which point the foolishness and leaps of logic would make sense because of his emotional makeup. That would still mean though that the morality, and logic of his actions are incorrect. Their entire plan is rooted in selfish emotions and desires.
Here's a little rant though:
The Uchiha can not deal with the realities of the world so they want to change the very nature of the natural world, and bend it to their own will, putting their own desires above anyone's free will because of their ability to bring mankind under their heel. In other words the only idea that appeal to is that might makes right, and sense they are strong they can force the world to change for them based on whatever they desire, even if it's based on simple emotionalism. Of course I don't think Kishimoto even understands that.
Hell the only reason Sasuke was "saved" is because Naruto can punch him just as hard as he can punch Naruto. Sasuke couldn't overcome Naruto, the same way Sasuke could overcome other peoples strength so he relented to Naruto's will. It's another reason this story is so thematically a mess, and just another reason the ending puts people in a foul mode. There is no moral victory for what's right... one persons might was just shown to be the equal of another so the negative force in the story stopped acting. Naruto didn't make Sasuke see that his actions were wrong... he just proved that he was to big of an obstacle for Sasuke to overcome so Sasuke stopped his plan.
By valid, I mean valuable, worthy of note, worthy of consideration, of equal merit, etc. Obito's actions were wrong, but that doesn't mean his reason didn't have any value to it (i.e. didn't have any validity). He is considered evil, not because of his reason, but by the way he chose to act on those reasons. If you stuck his reason for wanting to change the world inside a vacuum along with Jiraiya, Madara, Hashirama, Minato, and Hagoromo's reasons, you'll see that his reason for wanting the change is the same as all the latter mentioned. When you boil it down, they all hated the way the system worked. That sentiment by itself doesn't make any of them good or evil, what differentiates them is the way that they chose to pursue that change.
I agree with your rant though. I feel like Kishi tried to excuse Sasuke with that garbage curse of hatred nonsense, as if it only applied to the Uchiha. The only time he offered any real redemption to a character, ironically, was Obito. Sasuke got off way to easily.
