I don't have any problem killing any on the poll. The only exception from my wrath is when I am playing a game where you aren't supposed to kill innocents, such as playing as a "good" character in Fable or Fallout. I wasn't bothered by killing the dogs in Call of Duty 4 because they would kill me if I didn't kill them, although the snapping of their necks was a little brutal... at first. Also, in Oblivion I don't kill innocent bystanders because I don't need to get a bounty on my and spend my hard earned looting money.
EDIT: I wanted to kill the children in Fallout 3 SO BADLY! Those little bastards in Little Lamplight deserve to be hit with experimental Fatboy that launches 7 or 8 mini nukes!
