I think everyone's capable of killing, given sufficient duress, even the most defiant of pacifists could be brought around to kill.
However, whether one can kill or not is neither here nor there. The question(s) you should ask is: how would you react after you have killed another human? How would you react after a week? How would you react after a month? How would you react after a year? Or rather, how do you deal with the emotional maelstrom that comes with knowledge that you've ended a human life (from your own volition or otherwise)?
And unless the answer is: I honestly don't know (to any of them), then the person's either a fucking liar or a bloody idiot (selected military/law-enforcement personnel, murderers, perpetrators of manslaughter etc. notwithstanding).
So to answer, yes, I'm perfectly capable of killing and would do so if circumstances necessitated it without contradicting my belief of how I should live my life.
How I'd be living after the event is purely up for conjecture, but I can tell you that I'd probably be in the gutter for at least a few years.
