I'm assuming that King Fritz has full control over the Wall Titans, so he would be able to command them to attack only Marley towns and spare the Eldians.

But  SkeletonTitan,  your point about the unique layout of the walls is a very interesting one. King Fritz appears to have planned the layout of the walls by taking the presence of the Titans outside them into consideration. Case in point: The presence of districts like Shiganshina in order to concentrate titan activity shows that he planned his utopia with these mindless titans in mind, the same mindless titans which Marley supplies to Paradis island.

Which got me thinking, what if, just maybe, 107 years ago, King Fritz made some sort of deal with the leaders of the Marley government? King Fritz would cede control over the continent to Marley, while Marley would in turn supply mindless Titans (Eldians who disagreed with King Fritz) to Paradis Island to help maintain the illusion of a world overrun by Titans to keep the people in line.
