Just finding one human among these monsters are already difficult. Especially since some of the monsters are humanoid. Though I wonder why they modified a goblin into a human? Seeing them wearing loincloth and lifting a wooden club is embarrassing as a human race.
But seriously, did the cult turns a human into a monster by injecting the monsters' gene into human's body? Just how low can they be?
And why is the stupid Evil God wants to destroy the world? What kind of grudge does he has? At least if he's trying to conquer the world, I can understand that. Wanting to be the one above everyone. Becoming a real god in the end.
A way for someone to be recognized as a god by the people is simple. Even I know that. They just need to have the power to decide people's lives. Conquering the world is also one way to be recognized as a god. Though I don't know if there are real gods or not, a human being recognized as a god is quite simple. Though the method is difficult.
