Apparently it was always "a good time" for killing humans
Humans are going to be resurrected. It doen't matter how many of them get killed. They are so fragile, killing them is so easy. Besides they get new life in the end. Spirit creatures are tougher, they are not so easy to bump off. First they have to have a few powers removed, like no more tranforming into humans, etc. Then their older brother has to get new powers. When that happens look out demons! War in heaven. Maybe this war takes 2000 years or so. In the mean time the puny humans think they have been abandoned by the Queso Grande and have wars of their own trying to kill each other off. When the war in heaven is won the bad demons are kicked down to earth. (Ya Like we need that!) And more humans get in the way and get killed off. But of course they should be happy about that. Lift your heads up and all.
It is so simple.
