I think the homeland are the descendants of the original creators of the titan technology (but has lost much knowledge of it), they possess quite an understanding of human anatomy and biology and have advanced lab technology relative to the wall humans.

The technology's original purpose is unknown, but most probably, it was invented as an invincible bioweapon by a country/organization. It is hard to know what kind of titans were THE first titans, since the serum can indunce virtually ANY kind of titan, probably, the original scientists knew a whole lot more than even the most knowledgeable among the homeland. The "mindless" trait of most titans was probably intentional as is the capability of creating titans of any height, from colossal titans, to titans that are a little taller than tall humans. Its possible that both traits were originally unrelated, and were conjoined by design. Their desire to eat humans was also programmed.

The purpose of this, is to not have independent humans as titan soldiers, which would be the same as giving a nuke to each soldier in the military. Rather, have a bunch of unstoppable retards wreck havoc and ravage your enemies but have a single hive mind, able to control each and every one of them.

So then, the country/organization had researched the perfect weapon, unstoppable power and 100% unswerving obedience, accomplished through neurological and physiological bioengineering (of course adding the necessary magic).

So then, how did the so called "First King" enter the picture? he was probably 1 of the original scientists, or someone who stumbled across the whole thing, being a "captain" who was part of the lab personnel but didnt have clearance to know the full extent of the experiments being carried out, which were probably horrifying.

This whole thing was possibly why he calls humans "sinners", he snapped, being apalled by the horrors humans were capable of... all the "experimentation" and the ends of such research. So then, he stole the ultimate power (the coordinate) and used its full power to destroy the whole research as well as the organization, though some of them survived/fled and eventually became the present day homeland (though with far diminished power and knowledge). After that, fearing humanity could and would repeat such horrors and also fearing such knowledge could be researched by any other organization/country, he unleashed his full powers unto mankind, eventually leading to the world we all now love and know as "Attack on Titan".
