there was no widely recognized psychological or sociological concept known as the "borderline empathy paradox." It's possible that this term has emerged or gained significance , or it might be a term used in a specific context or by a particular group.
If it has been introduced as a new concept, I apologize for not having information on it. To better understand the "borderline empathy paradox," I recommend searching for more recent sources or academic articles that might discuss this term in detail. Online databases, psychology journals, or books on empathy and related topics could potentially shed light on this concept.
