Even though I planned on killing way more people in my second playthrough, I find myself actually not killing anyone. Aside from the deserters and traitors in the first mission I haven't killed anyone yet.
Especially as Emily the game hands you so many powers and tools to kill people, and yet it feels "wrong". It doesn't fit Emily and it doesn't fit the narrative. I have no reason to brutally kill guard #56 just because he happens to patrol the Dust District. I guess it's the same reason I don't kill enemy soldiers in MGS games, or why I prefer the stun gun in Watchdogs 2 when fighting cops.
Wouldn't even a yes/no be a spoiler?
Not really, as it's been stated by Arkane that the Low Chaos ending is the canon one.
