On Killing
The Psychological Cost of Learning to Kill in War and Society
The good news is that most soldiers are loath to kill. But armies have developed sophisticated ways of overcoming this instinctive aversion. And contemporary civilian society, particularly the media, replicates the army's conditioning techniques, and, according to Lt. Col. Dave Grossman's thesis, is responsible for our rising rate of murder among the young. Upon its initial publication, On Killing was hailed as a landmark study of the techniques the military uses to overcome the powerful reluctance to kill, of how killing affects soldiers, and of the societal implications of escalating violence. Now, Grossman has updated this classic work to include information on 21st-century military conflicts, recent trends in crime, suicide bombings, school shootings, and more. - Publisher.
Beyond its central premise, the book can be read through the connected lenses of Nonfiction. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.

A more thoughtful way into this book
This guide uses the edition details and category signals above to help you choose deliberately. It does not replace the author's work or a full review.
A comfortable full-length choice for steady daily reading.
Begin with its place in Nonfiction, then notice where the book resists that label.
Read for connection, not completion.
Mark one passage that sharpens the book's central concern and one that complicates it. That tension often reveals more than a quick summary.
Three questions to carry with you
- Whose perspective organizes the story, and whose perspective remains outside it?
- Which sources or lived experiences carry the author’s central argument?
- How does the book change the way you understand its larger subject?
