A person who enjoys making others feel bad and never feels guilt is often described as having traits associated with various personality disorders or negative behavioral patterns. Here are a few terms that may be used to describe such an individual:
Psychopath: A psychopath is someone who lacks empathy, guilt, and remorse. They may enjoy manipulating and harming others without feeling any sense of guilt or empathy for their actions.
Sociopath: Similar to a psychopath, a sociopath also lacks empathy and may engage in harmful behaviors without remorse. The terms "psychopath" and "sociopath" are sometimes used interchangeably, but there are some nuanced differences between the two.
Sadist: A sadist is someone who derives pleasure from inflicting pain or suffering on others. They may enjoy causing emotional or physical harm and may not feel guilt or remorse for their actions.
Narcissist: A narcissist is someone with an excessive sense of self-importance and a lack of empathy for others. They may enjoy manipulating and demeaning others to boost their own ego and may not feel guilt about their actions.
It's important to note that diagnosing someone with a specific personality disorder requires a comprehensive evaluation by a qualified mental health professional. Additionally, some of these terms can be used loosely or inappropriately in everyday language, so caution should be exercised in applying them to individuals without proper assessment.
If you believe someone you know may be exhibiting harmful behaviors and lack of empathy, it's essential to encourage them to seek professional help from a qualified therapist or counselor.
