Mercy
noun /ˈmɜːsi/ — Compassionate treatment of someone in one's power — the choice not to punish when punishment would be justified.
Definition
Compassion or forgiveness shown toward someone whom it is within one's power to punish or harm; an act of kindness, compassion, or favor.
Beyond the definition
Mercy is the active choice not to use the power you have — it requires that you could punish and that you don't. This is what makes it different from kindness (which makes no such calculation). Mercy is exercised from strength, not weakness.
Origin & history
From Old French merci — reward, pity (from Latin merces: reward, from merx: goods). From 'payment' to 'kindness' — mercy as the gift beyond what was owed.
