The internet is now ablaze with videos and articles explaining "narcissism". We realize that, as human-beings, we cannot read other peoples' hearts. Some narcissists, who now seem incorrigible, may actually someday change from being narcissists to being decent human beings. But this may take them a thousand years. For now, within our current life-expectancy, we just can't afford to "wait around", PINNING OUR HOPES on them making this change-for-the-better sooner rather than later. For now, we must recognize a narcissist whenever we encounter one, and take the necessary precautions to avoid being harmed by him.
Here's a short quote from a good article:

"6. Professional Power over Others
Narcissists seek positions where they have power over people in need. Thats why you can find many of them in fields like teaching, self-help, religion, politics, law, mental health, medical care, and so on. They prey on people who are in need. They abuse and perpetuate systemic and institutional issues to do that, too.
By being in a position of authority, legitimately or not, they can be perceived as moral, noble, caring, giving, competent and feel better than others. But it doesnt matter to them that they hurt other people, because, after all, others are just objects to serve their needs."
