Psalm 5:9-13 is a bible verse in the New International Version. It says: "Not a word from their mouth can be trusted; their heart is filled with malice. Their throat is an open grave; with their tongues they tell lies."
It was an alright game. There were some jumpscares that land and others were a miss. And if I have to guess on the premise based on the title and how your character looked, I'd say that he was one of those religious psychopaths who slays those whom he thinks offended God... and he's one of the offender, which is why he also punishes himself.
