Show mercy is an act of kindness and compassion towards someone who has wronged you or done something that deserves punishment. Sparing someone means to not punish them for their actions, relenting means to give up on punishing them, and forgiving means to let go of any resentment or anger towards them. Showing mercy is a way of showing understanding and compassion towards someone who has done wrong, and it is often seen as a sign of strength and maturity.
