Yeah and they also are REEING how Kruger and Grisha are helping. At first it makes no sense but then you remember that the former didn't want any of his own race to die while Eren is killing everyone outside of the island including other Eldians and the latter was told to save Mikasa and Armin who Eren is being a cunt to and even without that Mikasa is his daughter who Eren is trying to kill.
Kruger and Grisha's goals aren't particularly different-- it's just that Grisha had to explain to Eren what he needed to do in a high-pressure situation (he lost his wife to his Titanized compatriots and got goaded into murdering a whole family by his son from the future because Karl was such a
kuck cuck that he made his cuckoldry a feature of the Founding Titan).
Your explanation otherwise makes sense, though Kruger is made a hypocrite through it because he sacrificed scores of Eldians because he believed in his beleaguered mind that he was doing it for the sake of Eldia. In Grisha's case, you'd think he'd have understood that Eren's somewhat trying to do that, to the point that Armin is detained rather than killed outright-- not to mention that they came and put themselves in that danger.
They also act like Eren is free despite the fact Eren is literally a slave to his future memories and his genocidal tendencies are no different from how he wanted to kill all titans when he was a kid.
I disagree; when he was a kid, the Titans were a malevolent
concept that ruined his life and killed a lot of people he held dear. Everyone would have thought differently of them if they had known that Titans were transformed humans living a hazy nightmare desperately and instinctively searching for a Titan shifter so they can return to human form, and they ended up thinking differently of them after they discovered that reality.
Eren as an adult actively struggles with his plan to genocide the world outside Paradis,
because he can't make abstract the existence of that world. He moved and lived among them, realized the outside world wasn't drastically different than the one in which he grew up in, and now became aware of some of the people he'd be trampling over. It's practically a reversal of his arc regarding his understanding of the Titans-- starting out wanting to kill the Titans as though they were feral animals (and they effectively were), he becomes sympathetic regarding the Titans because he realizes that they're humans trapped in a waking nightmare. In contrast, recognizing the humanity of the world that opposes the existence of Eldia, he
dehumanizes them all to a generalized threat (and for all intents and purposes,
they were-- diplomatic and humanitarian appeals didn't work because their fears were justified, and the Eldians of other nations couldn't but look after themselves) because he can't find a positive solution wherein he can do otherwise.
Regarding Eren's "freedom", I think you're right. Kenny said that everyone's a slave to something, and there's been no argument posed against it-- only Eren's declaration that he found it.
