It's honestly just weird to have a justice system that is entirely based on rousing the emotions of the jury for a verdict when you have gods who actively watch over the world, know all the facts, but don't do anything when people lie under oath to those very gods. And it's even stranger that adventurers can just waltz into a monster's home, attempt to kill them to steal their possessions, fail because the monster fought back and won, and then put on a witch trial to essentially just have them crucified by the gods because the adventurers were too weak to win on their own and were piss babies about it. Especially in a world with a tangible level system that lets you accurately assess something's strength and danger. It's like if a knight charged at a tank, lost, and then the King was allowed to call the tank to stand trial for "murder".
The worldbuilding is so inconsistent with the ideal of "justice" that is seemingly brought about by the gods and their intervention, yet it is completely opposite what they want, abusable, and basically just a vehicle for human oppression of the rest of the world. The consistency in what is divinely enforced is absolutely wishy-washy, because if they can enforce appearance in the court to even Dragons who are bound from their very birth to a cave to defend treasure, then they can at least enforce honest testimony by swearing the oath, especially if they're also the ones divvying out "divine punishment".
