Probably just autistic, I mean as far as I know he hasn't been diagnosed but he's checking a lot of the boxes. And the way he views the world and basing conclusions on those views make sense to me in that context.

He's just more rigid and extreme in approaching the world from that frame of mind than most people are. Thus sometimes leading to "bad" takes where his intentions are probably not terrible in the way people think they are.

I really enjoyed Paradise Killer, a fun murder mystery game with a really solid soundtrack and neat visuals. I had a great time exploring the island uncovering its secrets and getting to know the remaining characters, and when I finished the game I was done. No loose ends or unanswered questions left, just a nice experience to remember (and a soundtrack to occasionally revisit)
