Virtue (the victims)

Does the highlighted sentence say that "the real virtue of war is the victims of war, therefore the virtue of war has nothing good"? Does "virtue" here mean the opposite of "vice"?

Context:

Callot’s prints, numbered sequentially, form a visual narrative on the war’s human tragedies. The low-numbered prints depict recruitment and early battle experiences; the next ones, plunder, looting, and torture in farms, convents, homes, and churches; the final prints, brutal punishments and the resultant maiming and poverty. In total contrast, in the last plate, a general rewards his good and loyal troops. The moral is clear: crime disguised as virtue (the war) brings reward but virtue itself (the victims) brings nothing good. The quantity of plates devoted to the bad and the ugly suggests that the artist saw little room for good in war.
