The ending was pretty unexpected, all in all the villagers are actually pretty chill, they just accepted MC killing Mizuki and thus getting his position as town judge. They also accepted his proposal to lower the severity of the punishments with no drama, but with the caveat that the punishments now cover more offences and thus take place even more frequently than before. I wonder if that was the villagers' condition to lower the severity of the punishments or was something the MC propositioned as a sneaky way to take some revenge on the townspeople lol.
I thought this story was going to involve the supernatural, but it's just about several people doing what they think is righteous and clashing with each other over it. Pretty decent read IMO.
