Its a highly sensitive issue. The time of the 1st and 2nd world wars were very different.
The ordinary working people were much different than today. Those who signed up probably never had an inkling of what war was about. They joined up for a plethora of reasons. The Government of they day told them they needed to enlist, their friends and family were all doing it, they thought it was the only right thing to do. They would easily beat the Germans and it would all be sorted quickly. Few felt they could dissent.
Of course many were conscripted and had little choice in the matter.
In that era of course we didnt have war live on TV. All we had was fake Government propaganda.
Remember the Falklands war? we could see our own ships burning on the six o clock news ,people dying,casualties being rescued from the Sir Galahad as it was bombed by the Argentinians,,so far away and yet so real.
I have letters in my possession relating to the death of a young seaman aged 19 who lost his life on a /royal Navy ship bombed by the germans off the coast of Italy. After the war a memorial was built in plymouth i think . His mother who was poor wrote to the war office to ask if any help was available for train fare so she could attend the dedication ceremony as she lived in the far north of England. The reply said that no their wasnt. Those in power just used people as cannon fodder and claimed the glory for victory.
His body still lies on that ship in the depths of the Mediterranean sea along with his equally young friends.
I think it would be very different today.
