Why do they say malignant narcissist like it is a bad thing?

**giggle**.I like this.. much better to hold yourself in high esteem than to think of yourself as unworthy or never-as-good as the next one..Narcissist started to be viewed as an illness when the overly bright Physiologist/Physiatrist had to give a name to someone that was happy with themselves!!..Like the old song says.'Be good to yoursefl..Nobody else will"..This is a jewel of brilliance..Thank you Shannon..
