What if I think that a person does not deserve to be forgiven? Should I then not go ahead with forgiveness?
There is a difference between your belief that a person does not deserve forgiveness and your willingness to go ahead or not with forgiving. I would say that all people are worthy of being forgiven because all people possess inherent worth. All people are special, unique, and irreplaceable. Yet, forgiveness can take time and so if you are not ready to forgive, this is your choice. I would say that your not going ahead with forgiving has more to do with your own inner world (your willingness to forgive) than it has to do with who this other person is as a person, worthy of forgiveness.
