Possible to intentionally kill without "intention"?

The 5 criteria of killing 1) There is life present 2) The person knows "there is life present" 3) Intention to take away the life 4) Action or speech that causes "life is taken away" 5) Life is taken away Is it possible for a person to fulfil criteria 1, 2, 4 and 5 but not 3? For example, a person orders me to kill and I did it unwillingly. Many times, I've heard people insisting that it's not counted as killing because the intention to kill is absent. But I kind of disagree thus posting this question for advice. Perhaps, to explain my understanding. You know an action will cause life to be taken away but chooses to act upon it. That choice itself is the intention.
