Playing through the game trying to get clean hands trophy (kill no one), and i've already run into something that could be a problem on the second mission. I was getting rid of the gentlemen callers in front of granny rags house, but when i went to strangle the 2/3 guy, the 3rd guy turned around and used his blow fire move and while i was strangling the 2nd guy, he died either during the strangle or when he hit the ground. I was wondering if anyone knows if this will count as a kill against me. I know if you do kill someone in the game, you have to play through that chapter and all chapters after to get clean hands. Thats why im asking, chapter 2 is like the beginning of the game and i dont want to have to do it all over again. Thanks in advance.

also, does posioning the bottle street gangs elixer count as killing?

I'm pretty sure if someone dies after you've interacted with that person it will count as a kill. As in unconscious body gets eaten by rats or rolling into water, or lying too close to a fire etc. Same goes for deaths while you are interacting with a person. If your actions led to death (either direct or as a later, unintended consequence) it will count as a kill.

On the other hand, the game doesn't count it as a kill if you free a pack of rats and they kill someone as long as you didn't interact/hurt that NPC.

In your specific case, although it is probably quite the extreme example, I would believe that if the person died while you choked him, even if the "killing blow" was not delivered by you, the game will probably not be able to differentiate between that. You did something to someone, that person died = kill.

i knock someone out and they get killed for any reason and it counts against me? that svcks.
