I was calling your text revisionist not because you were wrong, but because it was comming the very common and unfortunate error of revisioning the old wisdom ( that btw is probably wrong ) by not only coming out with new information, but primarily by tossing out the fact old wisdom used to shore it's case out just because. All you said was true, it's wasn't just not all of the Truth.

Yes , Wall Maria has fallen. Yes, people were planning on conquering Paradis island for resources, yes, Tybur said something akin on "Paradis must die because scary Titans ". And all of that was being taken in account by the governement that the Yeagerists took down and actions were being taken. Paradis was rearming itself with something more than Titans and was working with countries that hated Marley, like our resident not-Japanese of this chapter, besides the fact that Paradis has, due to ncessity, the best anti-titan weaponry of their world.
Eren decided, wrong or right, that all of those effort were for naught and decided to go to Marley and force History to go in one direction by making a nice display of what a Titan can do in a urban enviroment, justifying the warmongers in Marley to launch a full scale invasion to Paradis. In fact Eren just gave them the best excuse possible to do so
Now, point one, would Marley actually invade for resources if Eren had not intervened? No one knows, TBH, but the cooler heads in Marley were somewhat concerned about Paradis anti-Titan weaponry. The hotheads were surely pinning to bomb Ira ... Paradis, though, but it was probably not the full scale invasion we see happening in here that they wanted ... Marley has other enemies that are just bidding for a opportunity ( all of this is in the manga BTW ) and overcommiting to conquering Paradis would not be wise. And , as shown on how hard of a time the Marley forces were having when they actually invaded, anything besides a full scale assault from Marley would probably fail ...
Second, and the reason I called Eren emo, are Eren actions more borne out of necessity or of his own very human judgement? In other words, if you had put any other person in place of Eren, would he consider the actions Eren took as the rational way of doing things, something that had to be done, regrettably or not? And in there even the mangaka says that no, it did not had to be this way ... hence the whole Zeke arc ... not that Zeke idea not was also harebrained IMO, but it proves that Eren proposed path was not universally acepted by someone that knew as much as him, that is my point after all .
And let's be honest, Eren, since the wall fell and his mother died, was always a barely contained ball of anger and not exactly the more rational guy around ... we would call it PTSD if was in our world. His whole worldview since Wall Maria fell was always that someone had to pay for it, Titans, Marley, God, it didn't mattered which, .... and for some reason, the mangaka decided to flip his "Must kill Titans" switch 180º around during the time skip. You can argue the flip is justifiable , maybe it actually was ( I don't think it was , but that is a opinion ), but pretending that Eren badly resolved emotions did not had anything to what he did and that what he did was a rational and calm decision anyone would take is disingenious.
