I believe that normal distribution curve applies to any profession and any community. NL killed six people, but in no way was it premeditated. (Still, horrible). The nurse that stays in my mind is KK (K.Lee) from Kelsey Berreth case. That situation was premeditated, and prompts the question, “what the hell was she thinking?” (And professionally, she was good!)
But such situations are outliers. Most nurses are dealing with the same issues that we all are, money, living conditions, dating, marriages, kid issues. We can’t hold people to the highest personal standards because lives are not easy, and stressors are many. People make mistakes, but they are usually average mistakes. Same with doctors - once in a blue moon, we’d read about a doctor who killed his wife, but most people are average, and have normal lives, with “normal” mistakes and achievements. JMO.
