Forgiveness doesn't mean that you deny the other person's responsibility for hurting you, and it doesn't minimize or justify the wrong. You can forgive the person without excusing the act. Depending on the degree and circumstance of the offense, (typically, in assault and murder), the victim can forgive without the need of the offender's interaction or permission. The offender should never ask for forgiveness if there is any possibility of hurting the victim any further. Forgiveness is the process of ceasing to feel resentment, indignation or anger for a perceived offense, difference or mistake, or ceasing to demand punishment or restitution. This definition, however, is subject to much philosophical critique. Forgiveness may be considered simply in terms of the person who forgives, in terms of the person forgiven and/or in terms of the relationship between the forgiver and the person forgiven. In some contexts, it may be granted without any expectation of compensation, and without any response on the part of the offender (for example, one may forgive a person who is dead). In practical terms, it may be necessary for the offender to offer some form of acknowledgment, apology, and/or restitution, or even just ask for forgiveness, in order for the wronged person to believe they are able to forgive. Most world religions include teachings on the nature of forgiveness, and many of these teachings provide an underlying basis for many varying modern day traditions and practices of forgiveness. However, throughout the ages, philosophers have studied forgiveness apart from religion. In addition, as in other areas of human inquiry, science is beginning to question religious concepts of forgiveness. Psychology, sociology and medicine are among the scientific disciplines researching forgiveness or aspects of forgiveness. The Prodigal Son is a well known instance of such teaching and practice of forgiveness. Some religious doctrines or philosophies place greater emphasis on the need for humans to find some sort of divine forgiveness for their own shortcomings, others place greater emphasis on the need for humans to practice forgiveness between one another, yet others make little or no distinction between human and/or divine forgiveness.
