Confidence is what allows people to overcome their inhibitions and fears, and giving them initiative to take action. Sometimes, this is not always the best thing. When it comes to altercations or arguments, empowering someone can cause them to take things too far. For example, in an argument, not arguing back and just being positive may serve to both irritate and empower the other party at the same time.
This causes them to think that they are correct and they will yap even more rather than just dropping it. When you make someone feel high and mighty, they feel as though they can do nothing, and will at times not let things go to further fuel their egos.
