"I certainly condemn the killing of innocent civilians". No you don't. That's BS you're telling yourself so you can feel unconflicted about what should be a simple moral calculus.
I am not sure what certifies your moral; God or logic or whatever that tells you that how you live your life is justified.
I do know that I have morals, though.
"Don't murder people" is pretty easy for me to justify categorically.
If you have to put a big [*] next to that which says "if my boss tells me to kill someone, it's okay", then you really don't have any morals.
That math is easy for most folks to do.
The thing that probably keeps you from being able to do that math is some relative certainty that you personally will never have to be on the "risk/benefit analysis" board for these kinds of murderers.
But that's an error.
