If i think someone's trying to destroy me then i can get triggered into wanting to destroy them...i've never hit or hurt anyone like that but i have damaged certain family members cars, been emotionally/verbally abusive towards them etc. But this has always been a reaction to how they've treated me. Not that that excuses such behaviour or means i've abducated responsibility, but i'm not sure i would have even developed a personality disorder had i just grown up around normal people...
