Robert Leckie said this quote

There was no feeling of dedication because it was absolutely involuntary. I do not doubt that if the Marines had asked for volunteers for an impossible campaign such as Guadalcanal, almost everyone now fighting would have stepped forward. But that is sacrifice; that is voluntary. Being expended robs you of the exultation, the self-abnegation, the absolute freedom of self-sacrifice. Being puts one in the role of victim rather than sacrificer, and there is always something begrudging in this. I doubt if Isaac would have accepted the knife of his father, Abraham, entirely without reproach; yet, for the same master, he would have gladly gone to his death a thousand times. The world is full of the sacrifice of heroes and martyrs, but there was only one Victim.
