Probably the other kids from the warrior project, sold at the tener age of 5-6 so that their family could live as an honorary Marley, think of them as Kamikaze...or maybe some desperate soul who wanted their family to be taken care of in exchange of their sacrifice.

I doubt Marley would create a cure for the mindless titans if they want them as an ultimate weapon...and if they do it's probably secret and they wouldn't release it useless the shifters rebel aganist them.
