BTW I am fully aware that Marley themselves are a horrible regime and would likely have no problem with wiping out all life on Paradis and taking their territory/resources once the main objective of securing the founder was complete. But despite their racist attitude towards eldians, they didn't actually wipe out the eldians within their reach on the mainland. They could have just killed them all and only kept enough alive for their warrior program if they so desired, but they didn't. They are allowed to live, albeit as second class citizens.

So I doubt they would actually want to commit genocide on the present paradis eldians once their innocence due to Fritz's brainwashing became apparent. They would likely be treated just like all the marleyan subjects of ymir rather than being exterminated.
