While this is true, not everybody is at the same point in their development to take this action. Those wounded words are a cry for help even if they are aimed in the wrong direction. I don't subscribe to it being selfish afterall, it is coming from the subconscious which is largely beyond our voluntary control. As compassionate, loving people, I believe we are more able to see unhealed hurts in others than ourselves. We tend to play our own pain down - part of the natural instinct to present ourselves in the best light (often referred to as ego). It is a choice to see yourself as you really are, not a responsibility. It requires a level of growth to be in a position where you are ready and able to take on the task of viewing your woundedness and then set about the healing process. In some cases, this might never happen because those wounds are there to aid your learning and shape your experiences here on Earth.
