Mercy

Mercy can refer to a compassionate behavior by those in power (for example, "mercy" shown by a judge toward a criminal by not punishing him (or her) as much as he (or she) might be punished). It may also mean compassionate action by a third party (e.g. a trip out of "mercy" trying to treat sick children in Africa). The word is very common in several religions (for example, the mercy of God).
