You expressed your opinion. I'm responding with mine. If you just want to lecture me about morality, please say so, but I'm not under any obligation to sit here saying "You're right, I agree with the things you're saying about the morality of my actions." A conversation means the other person gets to talk too, buddy.

By your own logic, none of you are actually under any obligation to kill each other - after all duress isn't an excuse for murder, right? I came down here to try to keep people from killing each other in an exercise the guy who saved my life was going to be running, something I was told was a perfectly valid result in that experiment, and now the board has shifted and I don't have my next step yet. You don't have to give a shit as much as I don't have to give a shit about what you're saying, but I'm trying to talk to you. But please, sit around complaining about my phrasing some more and then insisting you don't care what I do, it's really productive.
