If someone told me that talking about other people behind their back makes you a bad person, I would say that discussing others behind their back can be seen as a negative behavior, depending on the context and intent of the conversation. Engaging in gossip, spreading rumors, or saying hurtful things about someone without their knowledge or consent can be harmful and reflect poorly on the person engaging in such behavior.
However, it's essential to consider the reasons behind such conversations. Sometimes, people might share concerns or seek advice about a situation involving someone else. If the intention is constructive and not meant to harm or degrade the individual, it may not necessarily make someone a bad person.
In general, it's important to practice empathy and respect towards others, treating them as we would like to be treated ourselves. Openly communicating with individuals involved in a situation is often the most ethical and effective way to address any concerns or conflicts.
