A Dilemma For Solution.

The two calamities on the Origin gods reduced their numbers in the plane significantly and helped the Vampires to establish themselves quickly. The Vampires prospered in the absence of the ghouls after weakening the resistance of the plane, but they might need the Origin gods now.

On one hand, they could kill one Origin god to help Emperiti advance. On the other hand, they need the help of the Origin gods, and killing them while asking for help is unlikely to help them gain the support of the Origin gods. 

The circumstances created a dilemma. They can help Emperiti, but if it doesn't work, then they will not have any chance with the Origin gods. It is a serious decision to make considering that the Origin gods will certainly be able to seal the ghouls if they choose to help and hunting Origin gods is not easy at all.
