If it makes you feel any better just do like I did think of it this way you're not killing the same guys you killed during the campaign these are their replacements the names are the same because all these groups are military based so technically it's not a name it's a rank and you're basically killing them so the queen stay at the top of the food chain by showing her dominance by showing anyone else that could have that rank that she could easily have them killed so play nice. If you think about it like that it kinda fits but I dont know
