Holy War, Just War 
Exploring the Moral Meaning of Religious Violence

Holy War, Just War explores the "dark side" in Christianity, Islam, and Judaism by examining how the concept of ultimate value contributes to religious violence. The book states that religion has within its own conceptual tools the resources to understand its own dark side and that religious people must subject their religion to a moral vision of goodness and constrain those parts that make for violence and hatred.
