What i use to do when i want raiders to have a mood debuff, is to have a dumping site for corpses.
And to 'force' them to walk throu the dumping site is to have it 'open'. And all other ways to the base closed by doors.
It seems like they follow the easy way, not the shortes way.
And to have yor prisoners in check, well remove the legs? kinda disturbing, but you seem like a guy who likes that
