The Source/Cause of the Infection!

[ZombieNick]

As to what is the cause of the infection, I think the unmapped area in the hospital clearly points toward man's interference into God's realm. We have tread on to holy ground and are paying the consequences. My guess for who's to blame, my working theory (Well, that's until the next chapter comes along and changes everything.) is that the corporation that conducted the experiments and they are no longer in control and the Zombie King, reins supreme. (King Ink the First, anyone?)
