True. The quote by Harry Emerson Fosdick, an American clergyman and author, is true. The tragedy of war is that it often co-opts the noblest qualities of men - their courage, selflessness, and sense of duty - to do the worst things that human beings are capable of, such as killing, destruction, and injuring others. War brings out the best and worst qualities in men, and unfortunately, the worst qualities often overshadow the best. Thus, Fosdick's quote is an accurate description of the paradoxical nature of war and its impact on human beings.
