Yeah, as horrific as that sort of thing is...it isn't something common with Garlemald's army and it's something that happens within Eorzea as well. In fact, there's a lot of forced slavery that goes on within Eorzea. Ishgardian's often abuse their lofty positions to have their way with those that catch their eye. (I believe the DRK quests heavily touch upon that) and in the ROG quests it's revealed that there's a lot of unrest, murder and crime going on within Limsa's streets.
