The main difference between Mercy and Compassion is that the Mercy is a broad term that refers to benevolence, forgiveness, and kindness and Compassion is a love.
Mercy (Middle English, from Anglo-French merci, from Medieval Latin merced-, merces, from Latin, “price paid, wages”, from merc-, merxi “merchandise”) is benevolence, forgiveness, and kindness in a variety of ethical, religious, social, and legal contexts.
The concept of a merciful God appears in various religions, including Hinduism, Christianity, Judaism and Islam. Performing acts of mercy as a component of religious beliefs is also emphasized through actions such as the giving of alms, and care for the sick and Works of Mercy.
In the social and legal context, mercy may refer both to compassionate behavior on the part of those in power (e.g. mercy shown by a judge toward a convict), or on the part of a humanitarian third party, e.g., a mission of mercy aiming to treat war victims.
Compassion motivates people to go out of their way to help the physical, mental or emotional pains of another and themselves. Compassion is often regarded as having sensitivity, an emotional aspect to suffering, though when based on cerebral notions such as fairness, justice, and interdependence, it may be considered rational in nature and its application understood as an activity also based on sound judgment. There is also an aspect of equal dimension, such that individual’s compassion is often given a property of “depth”, “vigour”, or “passion”. The etymology of “compassion” is Latin, meaning “co-suffering.” Compassion involves “feeling for another” and is a precursor to empathy, the “feeling as another” capacity for better person centered acts of active compassion; in common parlance active compassion is the desire to alleviate another’s suffering.
Compassion involves allowing ourselves to be moved by suffering, and experiencing the motivation to help alleviate and prevent it. An act of compassion is defined by its helpfulness. Qualities of compassion are patience and wisdom; kindness and perseverance; warmth and resolve. It is often, though not inevitably, the key component in what manifests in the social context as altruism. Expression of compassion is prone to be hierarchical, paternalistic and controlling in responses. Difference between sympathy and compassion is that the former responds to suffering with sorrow and concern while the latter responds with warmth and care.
The English noun compassion, meaning to love together with, comes from Latin. Its prefix com- comes directly from com, an archaic version of the Latin preposition and affix cum (= with); the -passion segment is derived from passus, past participle of the deponent verb patior, patī, passus sum. Compassion is thus related in origin, form and meaning to the English noun patient (= one who suffers), from patiens, present participle of the same patior, and is akin to the Greek verb πάσχειν (= paskhein, to suffer) and to its cognate noun πάθος (= pathos). Ranked a great virtue in numerous philosophies, compassion is considered in almost all the major religious traditions as among the greatest of virtues.
