I bring down the wicked, but may bring down the good if misused. Sometimes my requirements are harsh. Some make their living seeking me, some by commiting crimes against me, some purely for their own benefit, and some pretend to seek me but really thwart me. Mercy may restrain me, but I can never be escaped in one’s mind or before the Final Judge. Equity and the sword are my strong companions. I sometimes leave everyone touched by me unhappy evem when I am performed perfectly. What am I?
