User blog comment:Miskos3/Fairy Tail Episode 180: Garou Knights, Review/@comment-24257713-20140506183830/@comment-7418318-20140507082247

The guy who died in the tunnels with all the magazines doesn't really have a connection with the Garou Knights.

At least in the manga I got the feeling that they only killed those criminals that got too close to the exit. And with the massive size of Hell's Palace, it only makes sense. They would need hours to scour the entire place, so better to just sit at the only exit and wait of someone comes to you.

That guy just never got into their cordon of death and thus was left to rot by himself.

Or the Garou Knights were away to execute an enemy wizard on the outside for a while. I doubt they only exist to barr the way out of that place.
