The life even of the most useful man, of the best citizen, is not to be hoarded if there be need to spend it.

Context

“I freely sent the men for whom I cared most, to where death might smite them; and death often smote them—as it did the two best officers in my regiment, Allyn Capron and Bucky O'Neil. My men would not have respected me had I acted otherwise. Their creed was my creed. The life even of the most useful man, of the best citizen, is not to be hoarded if there be need to spend it. I felt, and feel, this about others; and of course also about myself. This is one reason why I have always felt impatient contempt for the effort to abolish the death penalty on account of sympathy with criminals.” source
