surely it's a case of priority(?) take care of the living then tend to the dead they would want us to. you are right.
for arguements sake we shall say that ghosts exsist. you have just been killed and 2 of your' friends are badly wounded would YOU want to be buried first or for someone to save your friends lives then come back for you?

i know which i would choose.

that is the nature of sacrifice.
putting the bigger picture before yourself, and that is why we must never forget the bravery and selflessness(?)that these soldiers showed.

it is just as disrespectful to blame ones action on being in the military and to think that you have priority over everyone else.
