Are people with borderline personality disorder (BPD) violent? The short answer is "no," most people with BPD are not violent. There is some research, however, that indicates that people who have been charged with violent crimes are more likely to be diagnosed with BPD than people who have not been charged with crimes.
Unfortunately, many people misinterpret this finding to argue that people with BPD are at a high risk of committing serious violent acts. This is just not the case, most people with BPD do not engage in serious violence, and many do not report any aggressive behavior. However, if you have BPD and are prone to physical aggression, or if you have a loved one with BPD who you have seen be aggressive, getting help early is your best bet.
