The "humanists" in here really need to lighten up. Seriously in Silent Hunter III you could make the case that you were sinking unarmed merchants and you were supporting Hitler and the holocaust. Of course that isn't true. The point of simulations isn't to become another person but to do things you wouldn't normally do, i.e. COMMAND A SUBMARINE! Thus in real life I do not command a submarine and thus do not shoot survivors of vessels during WWII. However if I am playing a game I would like to have both of these options open to me as they are things I don't do in real life but would like to do in a fictional patrol where no harm is done to anyone.
