There were some who didn't like doing it and didn't...some who didn't like it, but saw it as necessary, and I am sure, some who liked it very much.
It was accepted. War sure does suck.
I lived in Japan and the Philippines when I was a kid, and in the PI, the war seemed very real (in the sixties). As Boy Scouts, we hiked the path of the Bataan Death March, which has markers.
That is going to be my next adventure. I went to Europe a couple of years ago and the war is so much more real there too. I was fascinated by all the war material still around. In France and Italy you can still find Jerry cans rusting on the side of the road or being used as planter boxes. There are places in Belgium that the local police still have to go out and detonate unexploded artillery shells. What is really cool is that a lot of those artillery shells that didn't explode is because they were sabotaged by the Jewish and other slave laborers to make sure that they would never explode.
