A variant of PTSD....

CONTEXT:
"Post Traumatic Stress Disorder (PTSD) has entered the lexicon of the average North American citizen since the Vietnam war. A new variant, “Perpetration-Induced Traumatic Stress (PITS)” entered the scientific literature in 2002 when it was clearly identified that American veterans of the Vietnam war who actually killed humans or believed their actions resulted in human death, were significantly more likely to experience PTSD than matched individuals who had not directly participated in human killing but only witnessed such violence."
