At the end of a mission, the mission stats will state how many 'hostiles', and how many 'civilians' you killed.
Which NPCs are considered hostiles, and which are considered civilians? Is there any easy way to know if an NPC is considered a hostile or a civilian? Also, does killing a civilian add more to chaos, compared to killing a hostile?
Instances where it is unclear whether an NPC is a hostile or a civilian:
(where they don't attack unless provoked)
He will fight you in a duel, if you do an optional mission objective.
- The Scavenger at the Royal Physican mission
She'll fight you if you choose to do an optional mission objective.
