history
Cited in Feng Yuxiang's memoir 《我所认识的蒋介石》(The Chiang Kai-shek I Knew, ch. 71): '我们最好是宽大为怀，不为已甚' — 'we should be magnanimous and not press too far.' 怀 here means 'one's heart/breast.'
usage
Often a polite plea — asking someone in a position of power (a boss, judge, parent) to show leniency. Common in formal apologies and courtroom speeches.
