I just finished chapter 2 and honestly, I no longer have the desire to continue reading this story. It was a combination of a lot of smaller things.
The unnecessarily long pacing and build-up to the murders take hours of characters basically going back and forth about nothing, I've been reading through this for most of 2 days and have only just got through chapter 2 with 1 conference per chapter, that's much to long.
The constant taunting and ridicule of the MC for completely reasonable things combined with characters randomly acting like completely different people at one point made me think there was some kind of mass chemical mental manipulation going on, induced by one character who causes the MC to go into a rage whenever he's around, half the time screaming nonsense and the other half is the only time he actually stops ignoring obvious issues and starts making sense. Now I think I was just reading into it too much and the story is just inconsistent.
The issue that ended it however is the incredibly strange morality and sense of "justice" of the characters. They seem to almost revel in the pain they cause the murderers after their revealed as such, everyone immediately says that the death of the murderer is deserved and a good thing. When the character known for being kind essentially told the woman who committed the murder, as she was breaking down about to be executed, that she was glad that she was being killed and that everyone hates her, I found it genuinely offputing. That wouldn't be an issue of course if the intent was to show these characters as crazy sadists, who think justice is about death and torture, but I got the impression that the game expected me to agree with them. It might seem like I'm being prudish or overblowing something but these things are difficult to express in text.
