I like to see that here we have demons not as nightmares to torture us but as another specie that was created and evolve in this world along with the human species. Since they have a humanoid look, they must have a common ancestor.
Kill all those humans and demons that discriminate against the other just because one thinks it is better than the other.
@Drake98 for the majority of the people yeah because the masses are ignorant and just fear everything but there are a few people in there that know what was going on in the church or institutions that were doing the experiment but didn't know the results or who "would get the benefits" of the research since they were not part of the church. For those people, it is eye-opening to know how wrong they were.
