This phenonemon has a name, my friend! We call it Narcissistic Personality Disorder. I am realizing today they are in every corner and that so many toxic manifestations the humanity has been enduring for so long are correlated to this disorder without us having been aware of it.

And is the kind souls don't do the effort to get knowledgeable about it (the reliable sources on YouTube--real experts-- are numerous; many books are also exploring the topic), the chances are high they would suffer tremendously and never stop questioning their sanity, given that this education is unlikely to be available in the official programs.

It simply doesn't serve the decision-makers who belong to this troubled group for their majority!

P.S. The most dangerous type of narcissists is the malignant narcissist. Many experts like to call it the "Saddistic Psychopath". They litterally feed on others' suffering. They are delusional and believe they're gods on a mission: getting rid of the "weak" folks, to be read the kind souls who have all the virtues they can't even dream of! They're the real human predators!
