Also this was a really good read:

Violence in Bipolar Disorder | Psychiatric Times

It goes into how violence in people with BP is usually not from the BP, but rather because so many people with BP have a history of childhood abuse / violent trauma, which exacerbates the mood disorder. However the tendency for violence when present is actually due to the comorbidity of childhood trauma and the mood disorder, not the mood disorder itself. So it touches both on how childhood trauma can exacerbate a mood disorder, as well as how this type of correlation is common enough to be worth noting, since the prevalence of violence among people with BP has almost nothing to do with the BP itself.
