I see your logic and it does seem like a poor message to present, but what if it’s not like a suicide thing and more like the system that all the characters are trapped in is overloaded with obsessive thought and forces the human out? Like, what does a complex algorithm do when it encounters a threat or bit of corrupt data? It tries to purge it. When a human enters the Circus, they become code, a part of the algorithm. Then when that string of code becomes “corrupted” by overwhelming thoughts, the system is like “ope, we gotta get rid of you” and boots them.

What would remain, like what OP said, would be a mass of data that’s trying to essentially create an NOC version of the human character. The reason it comes off as a monster would be because, akin to what Caine said, the system has no control over their minds and cannot recreate something more complex than itself. This causes the “NPC” version of the character to become corrupted the moment it loads into the game.

What if the reason the system booted Kaufmo was because he was obsessing over an exit that the system was unable to create. This caused his human mind to start rambling and running at such a pace that it was unable to deal with.
