I think you raise a good point, and IIRC during WWI and WWII there was also the issues of some troops finding themselves unable to fire even at enemy soldiers.

I think you raise a good point, and IIRC during WWI and WWII there was also the issues of some troops finding themselves unable to fire even at enemy soldiers. I agree with you that this is a healthy reaction that should be furthered; but I just mention it because there is no need to fear the Godwin hammer (which is kind of a foam toy anyway). But on the other hand, for therapy, and to help overcome traumata and phobias, I find this interesting. It's another one of those tools that can be used for good and bad, unsurprisingly. I think that yes, killing should hurt, and it should mess people up. But this also goes for the fact that soldiers get messed up for the actions they were enticed or even forced to do by civilians who were mislead by politicians. This should also hurt, and it generally doesn't seem to. I know I did my fair share of blaming soldiers for showing up for wars, but it's just not that simple..
