False dichotomy. If you start taking responsibility one step earlier, you realize it is your responsibility not to let yourself get put in that position, that is, to an extent, you chose to let him put that gun to your head.
Ostensibly, yes, but it was the other person's choice to produce the gun and raise it. To ensure total avoidance of such situations, you would have to make sure you never come into contact with any armed Pringles advertisers, and since you never know for sure who or where they are, you would have to live your life in complete physical solitude.
