Alice Lynd & Staughton Lynd 
Moral Injury and Nonviolent Resistance [PDF ebook] 

When ordinary people have done, seen, or failed to prevent something that betrays their deeply held sense of right and wrong, it may shake their moral foundation. They may feel that what they did was unforgivable. In this thoughtful book culled from a wide range of experiences, Alice and Staughton Lynd introduce readers to what modern clinicians, philosophers, and theologians have attempted to describe as 'moral injury’. We can take heart from the exemplary actions by individuals and groups of individuals described in this book.
