The same feeling can be either appropriate or inappropriate, functional or dysfunctional, healthy or unhealthy. It is important to understand the difference Hurt can be very functional. We can learn from it. Healthy anger is good. We should feel angry when faced with racism, bigotry and inhumanity.
Guilt can be appropriate.
There are some things that have been done we should be ashamed about individually and corporately. Expressing grief can be an act of healing at times. On the other hand when we blame others for our hurt we become victims rather than victors. Raging at others makes us out rather than in control. Carrying unwarranted guilt causes us to become powerless rather than powerful.
