I use to view pride as sinful. It is after all one of the seven deadly sins. But I have come to view it as a virtue. It is the golden mean between undue humility and vanity. Both are opposite extremes of pride - one being deficient and the other in excess.
A properly proud person has an accurate assessment of their own worth, neither boasting about achievements nor downplaying genuine accomplishments.
It never sat right with me to view pride purely as sinful. The thought always came back to me as I watched DBZ in my younger days with the prideful Vegeta. His pride wasn’t always something I considered bad.
