Can you give me an example of when forgiving is not a good option?
Yes, and here are two examples. For example 1, the one who might forgive realizes that there really was no injustice. There was, instead, a misunderstanding between two people. Under this condition, forgiving is not a good option. For example 2, the person truly was treated unjustly by another, but this happened very recently. The one considering forgiving is not ready and needs some time to work through the anger. In this case, it may be best to wait, process the anger, and then decide if forgiving is the way to go now. Forgiving is a free will choice and sometimes we need time to process what happened and to examine our inner world before starting to forgive.
