According to the unspoken rules of politically correct videogame murder:
If someone is a soldier or criminal holding a weapon, it's completely OK to murder them in a videogame, but if they're an unarmed civilian it's not OK to murder them unless they're working for a corrupt organization. If they are working for a corrupt organization, feel free to murder away even if they're unarmed. If you are to murder unarmed civilians who are not working for a corrupt organization, make sure that you murder only adult males, since murdering women and children is much more terrible. Murdering anyone infected with a disease that causes them to behave violently, is OK, regardless of age, gender, or affiliation with corrupt organizations. Unless too many of them are black.
In games where the player character is a villain, it's generally OK to murder any male NPCs, especially soldier types, but generally murdering females is unacceptable unless they're not quite human or soldier types.
Clearly, this game has not done enough to qualify the murder as politically correct. May I suggest labeling the civilians as evil cultists of some sort?
