I would not feel guilty, yes the subject matter is powerful..but then that should mean a much better job was done at least on the presentation. There really is no reason for the prints to be pulling away from the mount and as to the quality of the exposure/image...do you think it was any more difficult than what the guys during WWII went through or the other pj who have brought back so many Good images (and some of them were just trying to stay alive). I would think that at the very least a strong effort with the presentation should have been made..based on you description that was not the case.
