Wretched Gods

Usually, people would think of gods as a kind existence. They care about life and are without prejudice, it's the people who interpret it wrongly. But what if a god asks you to eliminate the enemies? Ones which did nothing wrong? Suspicious, right?I have been summoned (cliche) to another world by gods of the humanity, and their request was for me to eliminate the beasts and demons of that world. But, I'm the one who decides what I do. I'll follow what they say for now, and see what's around me with my own eyes.
