So basically satan kills off all the humans for a better view of the sky. Not like a bloodthirsty unreasoning demon is going to appreciate the "better view", they might appreciate the prey though. So it's kind of hard to figure that Satan killed off the humans for the demons.
Notice that the comic treats demons like spirits, but talks about them like a race. The combining with humans sounds alot like possessing, and it talks about teleporting demons as a excuse for why you don't see them enter the body (guess they teleport right in) but even the suicidal demons didn't show themselves. All high end demons with teleport? Not like you can get abilities like that from merging with anything.
And what's with all the possesed mothers etc? It says you have to completely abandon reason to be possessed, so what, mothers don't think?
And with Satan having so much power, why did he even bother with getting humans to turn on one another.
