I agree with you that people hearing voices does not necessarily mean they are violent or dangerous. The majority of people who hear voices have never and will never hurt anyone.

Jehanne d’Arc technically never took a human life directly…but she’s famous for being a rallying symbol of France and strategic wartime leader. That doesn’t exactly make her hands clean even if she never technically killed anyone. Shes also reported as having had a pretty vicious temper that lead to her doing things like chasing prostitutes with a sword which isn’t exactly the epitome of peaceful and undangerous.
