Borderlines vs Narcissists (difference) - Prof. Sam Vaknin

"Borderline’s good object is compensatory: her misbehaviors and dysregulation belie it. Uses external regulation and fantasy to avoid the latter and thus affirm the former. Narcissist’s misbehaviors are compensatory, intended to belie his/her bad object. Uses external regulation to enhance the former and thus deny the latter." Prof. Sam Vaknin
