The JIDA isn't trying to protect the humans. The JIDA is trying to gain more power. They just happen to believe in their own superiority and use human soldiers. A human that cannot become a useful experiment is no good to them. Although they kill the vampires, like on Shinoa Squad's first mission, they do not have any interest in saving the vulnerable human livestock once their vampire protectors are gone. This is one of the more crucial details the anime left out.

Of course, their hunger for power is one of the key causes of the Apocalypse in the first place. They did not care if the rest of humanity were killed off. The seventh volume of Catastrophe ought to clarify their involvement a little more.

Ferid is considered to be very abnormal among the vampires. The vampires typically desire blood and nothing else, but he goes and makes things "interesting."
