Pride per se is not bad unto it self but what you take pride in and how much you hold on to it, that is the difference.
Taking pride in a difficult accomplishment and allowing yourself to bask in the moment of success is very important, healthy and rewarding.
Holding onto that moment too long, and or taking pride in a simple things like a personal physical attribute is where pride becomes malignant and narcissistic
There is a positive and a negative to pride.
Unfortunately it is all too easy to fall on the negative side as it is with most things of this world
