{ABSTRACT} The casualties of war are numerous and widespread. Two types are most familiar to the general population of Americans: deaths and serious bodily injuries. However, there are other serious psychological effects of war, such as resentment, anger, and hatred that remain at the margins of the healthcare radar. Uncontrolled and unmanaged resentment, anger, and hatred can have destructive consequences for veterans and their families. One solution for overcoming and dealing with these vindictive passions is learning to forgive.
